The Game Exective's

A golf club is used in the sport of golf to hit a golf ball. Each club is composed of a shaft with a grip and a clubhead. Woods are mainly used for long-distance fairway or tee shots; irons, the most versatile class, are used for a variety of shots; Hybrids that combine design elements of woods and irons are becoming increasingly popular; putters are used mainly on the green to roll the ball into the cup. A standard set consists of 14 golf clubs, typically consisting of 3 or 4 woods, 7 or 8 irons, a wedge, and a putter.

An important variation in different clubs is loft, or the angle between the club's face and the vertical plane. It is loft that makes a golf ball leave the tee on an ascending trajectory, not the angle of swing; all swings contact the ball with a horizontal motion. The impact of the club compresses the ball, while grooves on the clubface give the ball backspin (which would appear as a clockwise spin on the ball when viewed from the standpoint of a right-swinging golfer, or as a counter-clockwise spin when viewed from the standpoint of a left-swinging golfer). Together, the compression and backspin create lift. The majority of woods and irons are labeled with a number; higher numbers indicate shorter shafts and higher lofts, which give the ball a higher and shorter trajectory.

History

In 1744, the rules were officially documented and golf started to gain popularity. Many of the original golf clubs had wooden shafts and steel heads[dubious ] until this time period. Whether the game was being played in Scotland, Belgium, or any other country the golf clubs did not differ in the materials. However in the middle of the 18th century, it had switched to wood and only two golf clubs did not have wooden heads, the “niblick and the “cleek.” The golf club has changed so much through time, with the ability to be adequately fit to a player’s shape, size, age, or sex. In the beginning stages of golf, those who played would play with cut branches from trees and now have been revolutionized. There is no specific or set standardization as the club now can be varied in many ways. Before, the golfers only had wooden shafts, mostly wooden heads and/or heavy steel heads and thus led to ineffective playing. The golf balls were made of leather and feathers, known as featheries until the gutta-percha was introduced in 1848. The gutta-percha made the golf balls round and smooth making the accuracy difficult to control. Rubber was later included in the balls the players realized balls with dents or creases easily helped with the accuracy. The size and weight of the golf ball varied for a long time until it was decided on 1.62 inches and ounces. This was until 1932 when the USGA (United States Golf Association) in 1990 decided on 1.68 inches but left it at 1.62 ounces. These became the international rules as well and have not changed since.

Materials

The shafts of the Golf club woods were made of different types of wood before taken over by hickory. The varieties of woods include ash, greenheart, purpleheart, lancewood, lemonwood, orangewood, and blue-mahoo. In the middle of the 19th century the shafts were then being replaced by hickory wood. Despite this strong wood being the primary material, the long-nose club of the mid nineteenth century was still prone to breaking at the top of the backswing. The club heads were often made from thorn, apple, pear, dogwood, beech in the early times until persimmon became the main material. Golf clubs have been developed and the shafts are now made of steel, titanium, carbon fiber, or other types of metals. The shaft is a tapered steel tube or a series of stepped steel tubes in telescopic fashion. This has helped the accuracy of golfers. The grips of the clubs are made from leather or rubber.

Club Types

Woods/Drivers

Woods are long-distance clubs, meant to drive the ball a great distance down the fairway towards the hole. They generally have a large head and a long shaft for maximum club speed. Historically woods were made from Persimmon wood although some manufacturers - notably Ping - developed laminated woods. In 1979, TaylorMade Golf introduced the first metal wood made of steel. Even more recently manufacturers have started using materials such as carbon fiber, titanium, or scandium. Even though most 'woods' are made from different metals, they are still called 'woods' to denote the general shape and their intended use on the golf course. Most woods made today have a graphite shaft and a titanium, composite, or steel head. Woods are the longest clubs and the most powerful of all the golf clubs. There are typically three to four woods in a set which are used off the tee box and, if on a long hole, possibly for the second or even third shot. The biggest wood, known as the driver, is often made of hollowed out titanium with feather light shafts. The length of the woods has been increasing in recent decades, and a typical driver with a graphite shaft is now 45.5 inches (115.6 cm) long. The woods may also have very large heads, up to 460 cm³ in volume. It has a greater weight in the head and sole than in any other point in the club. This is also the same in irons. The shafts range from regular to extra-stiff depending upon each player’s preference.

Irons

Irons are golf clubs with a flat angled face and a shorter shaft than a wood, designed for shots approaching the green or from more difficult lies such as the rough, through or over trees, or the base of hills. Irons are used during the middle of each hole off the roughs, fairways or sand traps. There are long irons, medium irons, and short irons all with flat heads. They are called irons because they were made of metal. As with woods, there are special types. Wedges, invented by Gene Sarazan are a special type of iron that took the place of the “niblick.” They are heavy and shorter than other irons, with a less flat face to loft the ball higher. As with woods, "irons" get their name because they were originally made from forged iron. The higher the number gets on the scale, the lower amount of angle difference from 90 degrees. Irons are often hybrid, cavity-back or muscle-back. A hybrid is any iron that features a head very similar to a fairway wood; hollow steel or titanium with a shallow, slightly convex face. A hybrid head is usually marginally shallower and does not extend backwards from the face as far as a comparable fairway wood. A Cavity-back iron is any iron in which a small to large amount of the metal across the back of the head is removed, allowing that weight to be re-positioned on the perimeter of the head, farther away from the head's center of gravity. A muscle-back iron is any iron in which there is no cavity on the back of the head, i.e., the weight is more evenly distributed across the back of the clubhead.

Wedges are irons with a higher loft than a 9 iron (excluding the 10 iron, a club rarely used or sold that fills the increased gap between a pitching wedge and a 9 iron), which is typically lofted at about 42 degrees. Wedges are used for a variety of short-distance, high-altitude, high-accuracy shots such as hitting the ball onto the green ("approach" shots), placing the ball accurately on the fairway for a better shot at the green ("lay-up" shots), or hitting the ball out of hazards or rough onto the green (chipping). There are usually six types of wedges with lofts ranging from 45° to 64°: ---pitching wedge (PW 48°),--- approach wedge (AW 50°),--- gap wedge (GW 52°),--- sand wedge (SW 56°),--- lob wedge (LW 60°),--- and ultra lob wedge (LW 64°) ---. the gap wedge is sometimes called an approach wedge or Utility Wedge and labeled with AW or UW respectively.

Hybrids

Hybrids are a cross between a wood and an iron, giving these clubs the wood's long distance with the iron's familiar swing. These clubs generally are used instead of high-numbered woods and/or low-numbered irons, though some manufacturers produce entire sets of hybrids or "iron replacements" that incorporate hybrid design to add distance and forgiveness to a player's entire set of irons from 1 to pitching wedge. Most hybrids take the place of an iron, but the hybrid is easier to hit than its respective iro These clubs are often referred to as "Rescues" because the TaylorMade Rescue was one of the first clubs to utilize this design, as well as the use of the clubs to get one out of a tricky position (to be in fact rescued by the club).

Putters

Putters are a special class of clubs with a loft not exceeding ten degrees (except chippers), designed primarily to roll the ball along the grass, generally from a point on the putting green towards the cup. Contrary to popular belief, putters do have a loft (often 5 degrees from truly perpendicular at impact) that helps to lift the ball from any indentation it has made. Newer putters also include grooves on the face to promote roll rather than a skid off the impact. This increases rolling distance and reduces bouncing over the turf. Also present in some golfers' bags is the "chipper" which is designed for low-speed swings to lift the ball a short distance about 25 yards/23 meters, onto the green. The club can be used in place of the pitching wedge with an abbreviated swing to accomplish the same end. This club is used only on the greens and is the finishing club for each hole. These clubs were originally made of wood but have also been developed to metals as well. These are the shortest clubs of the set.

Chippers

Another variation of the putter, called the chipper, has a similar look, feel and general construction as a "normal" putter, but with a much higher loft, often 30-45 degrees. It is used to lift the ball over or out of the rough or fringe and onto the green with a motion similar to a putt. It can also be used for "lagging" (a putt made on the green from long distance for the sole purpose of setting up the ball for an easier second putt). A putter used for this purpose would require a harder stroke and the rough or fringe could affect accuracy. A high-angle wedge could have similar accuracy issues and could also damage the turf on such a shot if made carelessly. However, its use is generally limited; it is best-suited for short-distance play from close-cut grass on a terrain level similar to that of the green, and as such most skilled golfers choose to use a low-bounce, wide-soled wedge with a putting motion to accomplish a similar effect and save the space the club would take for a more versatile club.

Construction

Shaft

Loft and lie of a golf club.

The shaft is a tapered tube made of metal (usually steel) or carbon fiber composite (referred to as graphite). The shaft is roughly 0.5 inches (13 mm) in diameter near the grip and from 34 to 48 inches (86 to 122 cm) in length. Shafts weigh from 45 to 150 grams (1.6 to 5.3 oz), depending on the material and length.

Shafts are quantified in a number of different ways. The most common is the shaft flex. Simply, the shaft flex is the amount that the shaft will bend when placed under a load. A stiffer shaft will not flex as much, which requires more power to flex and "whip" through the ball properly (which results in higher club speed at impact for more distance), while a more flexible shaft will whip with less power required for better distance on slower swings, but may torque and over-flex if swung with too much power causing the head not to be square at impact, resulting in lower accuracy. Most shaft makers offer a variety of flexes. The most common are: L (Lady), A (Soft Regular, Intermediate or Senior), R (Regular), S (Stiff), and X (Tour Stiff, Extra Stiff or Strong). A regular flex shaft is generally appropriate for those with an average head speed (80–94 mph (130–151 km/h)), while an A-Flex (or senior shaft) is for players with a slower swing speed (70–79 mph (110–127 km/h)), and the stiffer shafts, such as S-Flex and X-Flex (Stiff and Extra-Stiff shafts) are reserved only for those players with an above average swinging speed, usually above 100 mph (160 km/h). Some companies also offer a "stiff-regular" or "firm" flex for players whose club speed falls in the upper range of a Regular shaft (90–100 mph (140–160 km/h)), allowing golfers and clubmakers to fine-tune the flex for a stronger amateur-level player.

On off-center hits, the clubhead twists as a result of a torque, reducing accuracy as the face of the club is not square to the player's stance at impact. In recent years, many manufacturers have produced and marketed many low-torque shafts aimed at reducing the twisting of the clubhead at impact; however, these tend to be stiffer along their length as well. Most recently, many brands have introduced stiff-tip shafts. These shafts offer the same flex throughout most of the Shaft, in order to attain the "whip" required to propel the ball properly, but also include a stiffer tip, which cuts back drastically on the lateral torque acting on the head.

Widely overlooked as a part of the club, the shaft is considered by many to be the engine of the modern clubhead. Shafts range in price from a mere US$20 to over US$1200. Current graphite shafts weigh considerably less than their steel counterparts (sometimes weighing less than 50 grams (1.8 oz) for a driver shaft), allowing for lighter clubs that can be swung at greater speed. Within the last ten years[when?], performance shafts have been integrated into the clubmaking process. Performance shafts are designed to address specific criteria, such as to launch the ball higher or lower or to adjust for the timing of a player's swing to load and unload the shaft at the correct moments of the swing for maximum power. Whereas in the past each club could come with only one shaft, today's clubheads can be fitted with dozens of different shafts, creating the potential for a much better fit for the average golfer.

Grip

In modern times, the grip has undergone a number of iterations. The large variety of models makes it far easier than in the past for a discriminating golfer to find a comfortable model.

Grip rules

According to the rules of golf, all club grips, with the exception of the putter, must have a circular cross-section. The putter may have any cross section that is symmetrical along the length of the grip through at least one plane. Grips may taper from thick to thin along their length (and virtually all do), but they are not allowed to have any waisting (a thinner section of the grip surrounded by thicker sections above and below it) or bulges (thicker sections of the grip surrounded by thinner sections). Minor variations in surface texture (such as the natural variation of a "wrap"-style grip) are not counted unless significant.

Regripping

Advances in materials have resulted in more durable, longer-lasting soft grips, but nevertheless grips do eventually dry out, harden, or are otherwise damaged and must be replaced. Replacement grips sold as do-it-yourself kits are generally inexpensive and of high quality, although custom grips that are larger, softer, or textured differently from the everyday "wrap"-style grip are generally bought and installed by a clubsmith.

Regripping used to require toxic, flammable solvents to soften and activate the adhesive, and a vise to hold the club steady while the grip was forced on. The newest replacement kits, however, use double-sided tape with a water-activated adhesive that is slippery when first activated, allowing easier installation. Once the adhesive cures, it creates a very strong bond between grip and shaft and the grip is usually impossible to remove without cutting it off. Note that the grip is sometimes lubed for easier removal.

Hosel

The hosel is the portion of the clubhead to which the shaft attaches. Though largely ignored by players, hosel design is integral to the balance, feel and power of a club. Modern hosels are designed to place as little mass as possible over the top of the striking face of the club, which lowers the center of gravity of the club for better distance.

Clubhead

Each head has one face which contacts the ball during the stroke. Putters may have two striking faces, as long as they are identical and symmetrical. Some chippers have two faces, but are not legal. Page 135 of the 2009 USGA rules of golf states:

"The clubhead must have only one striking face, except that a putter may have two such faces if their characteristics are the same, and they are opposite each other."

Page 127 of the USGA rules of golf states:

"A putter is a club with a loft not exceeding ten degrees designed primarily for use on the putting green."

Therefore, any double sided club with a loft greater than 10 degrees is not legal.

Ferrule

The decorative trim ring, usually black (It may have additional trim colors), that is found directly on top of the hosel on many woods and irons.

Regulations

The ruling authorities of golf, the Royal and Ancient Golf Club of St Andrews (R&A) and the United States Golf Association (USGA), reserve the right to define what shapes and physical characteristics of clubs are permissible in tournament play. Many recently developed woods have a marked "trampoline effect" (a large deformation of the face upon impact followed by a quick restoration to original dimensions, acting like a slingshot), resulting in very high ball speeds and great lengths of tee shots. As of 1 January 2008, the USGA and R&A have settled on a regulation that limits the acceptable "trampoline effect" to a coefficient of restitution (COR) – a measurement of the efficiency of the transfer of energy from the club head to the ball – of .830.

Other large scale USGA rulings involve a 1990 lawsuit, and subsequent settlement, against Karsten Manufacturing, makers of the PING brand, for their use of square, or U-grooves in their immensely popular Ping Eye2 irons. The USGA argued that players who used the Eye2 had an unfair advantage in imparting spin on the ball, which helps to stop the ball on the putting greens. The USGA utilized John L. Saksun, founder of Canadian golf company Accuform Golf, as a consultant to set up methods of measuring the unique grooves and determining PING's compliance with the rulings. Saksun, by proposing a cost-effective solution to help PING change the design of subsequent Eye2s, saved PING hundreds of millions. PING subsequently withdrew their US$100 million lawsuit against the USGA. Ping’s older clubs were "grandfathered in" and allowed to remain in play as part of the settlement. Today, square grooves are considered perfectly legal under the Rules of Golf. However, the USGA has determined that square grooves are illegal in elite-level competition. According to the USGA, as January 1, 2010, professional golfers on one of the top tours, or those attempting to qualify for one of the three Open Championships, will need to be utilizing new conforming wedges (those without square grooves). Moreover, those who plan to qualify for any other USGA championship will need new conforming wedges by 2014. In addition, this regulation might include amateur events as well. Casual golfers may use square groove wedges (and clubs) until at least 2024

The Berlin Wall

The Berlin Wall (German: Berliner Mauer) was a barrier constructed by the German Democratic Republic (GDR, East Germany) starting on 13 August 1961, that completely cut off West Berlin from surrounding East Germany and from East Berlin. The barrier included guard towers placed along large concrete walls, which circumscribed a wide area (later known as the "death strip") that contained anti-vehicle trenches, "fakir beds" and other defenses. The Soviet-dominated Eastern Bloc officially claimed that the wall was erected to protect its population from fascist elements conspiring to prevent the "will of the people" in building a socialist state in East Germany. However, in practice, the Wall served to prevent the massive emigration and defection that marked Germany and the communist Eastern Bloc during the post-World War II period.

The Berlin Wall was officially referred to as the "Anti-Fascist Protection Rampart" (German: Antifaschistischer Schutzwall) by GDR authorities, implying that neighbouring West Germany had not been fully de-Nazified. The West Berlin city government sometimes referred to it as the "Wall of Shame"—a term coined by mayor Willy Brandt—while condemning the Wall's restriction on freedom of movement. Along with the separate and much longer Inner German border (IGB) that demarcated the border between East and West Germany, both borders came to symbolize the "Iron Curtain" between Western Europe and the Eastern Bloc.

Before the Wall's erection, 3.5 million East Germans circumvented Eastern Bloc emigration restrictions and defected from the GDR, many by crossing over the border from East Berlin into West Berlin, from where they could then travel to West Germany and other Western European countries. Between 1961 and 1989, the wall prevented almost all such emigration. During this period, around 5,000 people attempted to escape over the wall, with estimates of the resulting death toll varying between 100 and 200.

In 1989, a radical series of political changes occurred in the Eastern Bloc, associated with the liberalization of the Eastern Bloc's authoritarian systems and the erosion of political power in the pro-Soviet governments in nearby Poland and Hungary. After several weeks of civil unrest, the East German government announced on 9 November 1989 that all GDR citizens could visit West Germany and West Berlin. Crowds of East Germans crossed and climbed onto the wall, joined by West Germans on the other side in a celebratory atmosphere. Over the next few weeks, a euphoric public and souvenir hunters chipped away parts of the wall; the governments later used industrial equipment to remove most of the rest. The fall of the Berlin Wall paved the way for German reunification, which was formally concluded on 3 October 1990.

Background

Post-war Germany

After the end of World War II in Europe, what remained of pre-war Germany west of the Oder-Neisse line was divided into four occupation zones (per the Potsdam Agreement), each one controlled by one of the four occupying Allied powers: the United States, the United Kingdom, France and the Soviet Union. The capital of Berlin, as the seat of the Allied Control Council, was similarly subdivided into four sectors despite the city's location deep inside the Soviet zone.

Within two years, political divisions increased between the Soviets and the other occupying powers. These included the Soviets' refusal to agree to reconstruction plans making post-war Germany self-sufficient and to a detailed accounting of the industrial plants, goods and infrastructure already removed by the Soviets. Britain, France, the United States and the Benelux countries later met to combine the non-Soviet zones of the country into one zone for reconstruction and approve the extension of the Marshall Plan.

The Eastern Bloc and the Berlin airlift

Following World War II, Soviet leader Joseph Stalin built up a protective belt of Soviet-controlled nations on his Western border, the Eastern bloc, that then included Poland, Hungary and Czechoslovakia, which he wished to maintain alongside a weakened Soviet-controlled Germany. As early as 1945, Stalin revealed to German communist leaders that he expected to slowly undermine the British position within the British occupation zone, that the United States would withdraw within a year or two, and that nothing then would stand in the way of a united Germany under communist control within the Soviet orbit.

The major task of the ruling communist party in the Soviet zone was to channel Soviet orders down to both the administrative apparatus and the other bloc parties, while pretending that these were initiatives of its own. Property and industry was nationalized in the East German zone. If statements or decisions deviated from the described line, reprimands and, for persons outside public attention, punishment would ensue, such as imprisonment, torture and even death.

Indoctrination of Marxism-Leninism became a compulsory part of school curricula, sending professors and students fleeing to the west. The East Germans created an elaborate political police apparatus that kept the population under close surveillance, including Soviet SMERSH secret police.

In 1948, following disagreements regarding reconstruction and a new German currency, Stalin instituted the Berlin Blockade, preventing food, materials and supplies from arriving in West Berlin. The United States, Britain, France, Canada, Australia, New Zealand and several other countries began a massive "Berlin airlift", supplying West Berlin with food and other supplies. The Soviets mounted a public relations campaign against the western policy change. Communists attempted to disrupt the elections of 1948, preceding large losses therein, while 300,000 Berliners demonstrated for the international airlift to continue. In May 1949, Stalin lifted the blockade, permitting the resumption of Western shipments to Berlin.

The German Democratic Republic (East Germany) was declared on 7 October 1949. By a secret treaty, the Soviet Ministry of Foreign Affairs accorded the East German state administrative authority, but not autonomy. The Soviets had unlimited power over the occupation regime and penetrated East German administrative, military and secret police structures.

East Germany differed from West Germany (Federal Republic of Germany), which developed into a Western capitalist country with a social market economy ("Soziale Marktwirtschaft" in German) and a democratic parliamentary government. Continual economic growth starting in the 1950s fuelled a 20-year "economic miracle" ("Wirtschaftswunder"). As West Germany's economy grew and its standard of living continually improved, many East Germans wanted to move to West Germany.

Emigration westward in the early 1950s

After Soviet occupation of Eastern Europe at the end of World War II, the majority of those living in the newly acquired areas of the Eastern Bloc aspired to independence and wanted the Soviets to leave. Taking advantage of the zonal border between occupied zones in Germany, the number of GDR citizens moving to West Germany totaled 187,000 in 1950; 165,000 in 1951; 182,000 in 1952; and 331,000 in 1953. One reason for the sharp 1953 increase was fear of potential further Sovietization, given the increasingly paranoid actions of Joseph Stalin in late 1952 and early 1953. 226,000 had fled in just the first six months of 1953.

Erection of the inner German border

By the early 1950s, the Soviet approach to controlling national movement, restricting emigration, was emulated by most of the rest of the Eastern Bloc, including East Germany. The restrictions presented a quandary for some Eastern Bloc states that had been more economically advanced and open than the Soviet Union, such that crossing borders seemed more natural—especially where no prior border existed between East and West Germany.

Up until 1952, the lines between East Germany and the western occupied zones could be easily crossed in most places. On 1 April 1952, East German leaders met the Soviet leader Joseph Stalin in Moscow; during the discussions Stalin's foreign minister Vyacheslav Molotov proposed that the East Germans should "introduce a system of passes for visits of West Berlin residents to the territory of East Berlin [so as to stop] free movement of Western agents" in the GDR. Stalin agreed, calling the situation "intolerable". He advised the East Germans to build up their border defenses, telling them that "The demarcation line between East and West Germany should be considered a border—and not just any border, but a dangerous one ... The Germans will guard the line of defence with their lives."

Consequently, the inner German border between the two German states was closed, and a barbed-wire fence erected. The border between the Western and Eastern sectors of Berlin, however, remained open, although traffic between the Soviet and the Western sectors was somewhat restricted. This resulted in Berlin becoming a magnet for East Germans desperate to escape life in the GDR, and also a flashpoint for tension between the United States and the Soviet Union.

In 1955, the Soviets gave East Germany authority over civilian movement in Berlin, passing control to a regime not recognized in the West. Initially, East Germany granted "visits" to allow its residents access to West Germany. However, following the defection of large numbers of East Germans under this regime, the new East German state legally restricted virtually all travel to the West in 1956. Soviet East German ambassador Mikhail Pervukhin observed that "the presence in Berlin of an open and essentially uncontrolled border between the socialist and capitalist worlds unwittingly prompts the population to make a comparison between both parts of the city, which unfortunately, does not always turn out in favor of the Democratic [East] Berlin."

The Berlin emigration loophole

With the closing of the inner German border officially in 1952, the border in Berlin remained considerably more accessible then because it was administered by all four occupying powers.Accordingly, Berlin became the main route by which East Germans left for the West. On 11 December 1957, East Germany introduced a new passport law that reduced the overall number of refugees leaving Eastern Germany.

It had the unintended result of drastically increasing the percentage of those leaving through West Berlin from 60% to well over 90% by the end of 1958. Those caught trying to leave East Berlin were subjected to heavy penalties, but with no physical barrier and subway train access still available to West Berlin, such measures were ineffective. The Berlin sector border was essentially a "loophole" through which Eastern Bloc citizens could still escape. The 3.5 million East Germans who had left by 1961 totalled approximately 20% of the entire East German population.

Brain drain

The emigrants tended to be young and well-educated, leading to the "brain drain" feared by officials in East Germany. Yuri Andropov, then the CPSU Director on Relations with Communist and Workers Parties of Socialist Countries, wrote an urgent letter on 28 August 1958, to the Central Committee about the significant 50% increase in the number of East German intelligentsia among the refugees. Andropov reported that, while the East German leadership stated that they were leaving for economic reasons, testimony from refugees indicated that the reasons were more political than material. He stated "the flight of the intelligentsia has reached a particularly critical phase."

By 1960, the combination of World War II and the massive emigration westward left East Germany with only 61% of its population of working age, compared to 70.5% before the war. The loss was disproportionately heavy among professionals: engineers, technicians, physicians, teachers, lawyers and skilled workers. The direct cost of manpower losses has been estimated at $7 billion to $9 billion, with East German party leader Walter Ulbricht later claiming that West Germany owed him $17 billion in compensation, including reparations as well as manpower losses. In addition, the drain of East Germany's young population potentially cost it over 22.5 billion marks in lost educational investment. The brain drain of professionals had become so damaging to the political credibility and economic viability of East Germany that the re-securing of the German communist frontier was imperative.

Construction begins, 1961

East German construction workers building the Berlin Wall, 20 November 1961.

On 15 June 1961, First Secretary of the Socialist Unity Party and GDR State Council chairman Walter Ulbricht stated in an international press conference, "Niemand hat die Absicht, eine Mauer zu errichten!" (No one has the intention of erecting a wall!). It was the first time the colloquial term Mauer (wall) had been used in this context.

The record of a telephone call between Nikita Khrushchev and Ulbricht on 1 August in the same year, suggests that it was Khrushchev from whom the initiative for the construction of the wall came. However, Ulbricht had pushed for a border closure for quite some time, and Khrushchev had been emboldened by US President John F. Kennedy’s tacit indication that the US would not actively oppose this action in the Soviet sector of Berlin. On Saturday, 12 August 1961, the leaders of the GDR attended a garden party at a government guesthouse in Döllnsee, in a wooded area to the north of East Berlin. There Ulbricht signed the order to close the border and erect a wall.

At midnight, the police and units of the East German army began to close the border and, by Sunday morning, 13 August, the border with West Berlin was closed. East German troops and workers had begun to tear up streets running alongside the border to make them impassable to most vehicles and to install barbed wire entanglements and fences along the 156 kilometres (97 miles) around the three western sectors, and the 43 kilometres (27 miles) that divided West and East Berlin.

The barrier was built slightly inside East Berlin or East German territory to ensure that it did not encroach on West Berlin at any point. Later, it was built up into the Wall proper, the first concrete elements and large blocks being put in place on 17 August. During the construction of the Wall, National People's Army (NVA) and Combat Groups of the Working Class (KdA) soldiers stood in front of it with orders to shoot anyone who attempted to defect. Additionally, chain fences, walls, minefields and other obstacles were installed along the length of East Germany's western border with West Germany proper. A huge no man's land was cleared to provide a clear line of fire at fleeing refugees.

Immediate effects

With the closing of the East-West sector boundary in Berlin, the vast majority of East Germans could no longer travel or emigrate to West Germany. Many families were split, while East Berliners employed in the West were cut off from their jobs. West Berlin became an isolated enclave in a hostile land. West Berliners demonstrated against the wall, led by their Mayor (Oberbürgermeister) Willy Brandt, who strongly criticized the United States for failing to respond. Allied intelligence agencies had hypothesized about a wall to stop the flood of refugees, but the main candidate for its location was around the perimeter of the city. In 1961, Secretary of State Dean Rusk proclaimed, "The Wall certainly ought not to be a permanent feature of the European landscape. I see no reason why the Soviet Union should think it is—it is to their advantage in any way to leave there that monument to Communist failure."

US President John F. Kennedy visiting the Berlin Wall on 26 June 1963.

In a speech on 26 July 1963, US President John F. Kennedy had acknowledged that the United States could only hope to defend West Berliners and West Germans; to attempt to stand up for East Germans would result only in an embarrassing downfall. Accordingly, the administration made polite protests at length via the usual channels, but without fervour. The Wall violated postwar Potsdam Agreements, which gave the United Kingdom, France and the United States a say over the administration of the whole of Berlin. A few months after the barbed wire was erected, the U.S. government informed the Soviet government that it accepted the Wall as "a fact of international life" and would not challenge it by force.

From the East-Side 1968 the "Baby Wall" with flowers was the nearest point for visitors.

US and UK sources had expected the Soviet sector to be sealed off from West Berlin, but were surprised by how long the East Germans took for such a move. They considered the wall as an end to concerns about a GDR/Soviet retaking or capture of the whole of Berlin; the wall would presumably have been an unnecessary project if such plans were afloat. Thus they concluded that the possibility of a Soviet military conflict over Berlin decreased.

The East German government claimed that the Wall was an "anti-fascist protective rampart" (German: "antifaschistischer Schutzwall") intended to dissuade aggression from the West. Another official justification was the activities of western agents in Eastern Europe. The Eastern German government also claimed that West Berliners were buying out state-subsidized goods in East Berlin. East Germans and others greeted such statements with skepticism, as most of the time, the border was only closed for citizens of East Germany traveling to the West, but not for residents of West Berlin travelling to the East. The construction of the Wall had caused considerable hardship to families divided by it. Most people believed that the Wall was mainly a means of preventing the citizens of East Germany from entering or fleeing to West Berlin.

An East German SED propaganda booklet published in 1955 dramatically described the serious nature of 'flight from the republic':

Both from the moral standpoint as well as in terms of the interests of the whole German nation, leaving the GDR is an act of political and moral backwardness and depravity. Those who let themselves be recruited objectively serve West German Reaction and militarism, whether they know it or not. Is it not despicable when for the sake of a few alluring job offers or other false promises about a "guaranteed future" one leaves a country in which the seed for a new and more beautiful life is sprouting, and is already showing the first fruits, for the place that favours a new war and destruction? Is it not an act of political depravity when citizens, whether young people, workers, or members of the intelligentsia, leave and betray what our people have created through common labour in our republic to offer themselves to the American or British secret services or work for the West German factory owners, Junkers, or militarists? Does not leaving the land of progress for the morass of an historically outdated social order demonstrate political backwardness and blindness? ... [W]orkers throughout Germany will demand punishment for those who today leave the German Democratic Republic, the strong bastion of the fight for peace, to serve the deadly enemy of the German people, the imperialists and militarists.

Secondary response

Kennedy appointed retired General Lucius D. Clay, who had been the Military Governor of the US Zone of Occupation in Germany during the period of the Berlin Blockade and had ordered the first measures in what became the Berlin Airlift, as his special advisor, sending him to Berlin with ambassadorial rank. Clay was immensely popular with the residents of West Berlin, and his appointment was an unambiguous sign that Kennedy would not compromise on the status of West Berlin. Clay and Vice President Lyndon B. Johnson arrived at Tempelhof Airport on the afternoon of Saturday, 19 August 1961.

They arrived in a city defended by three Allied brigades—one each from the UK, the US, and France (the Forces Françaises à Berlin). On 16 August, Kennedy had given the order for them to be reinforced. Early on 19 August, the 1st Battle Group, 18th Infantry (commanded by Colonel Glover S. Johns Jr.) was alerted.

On Sunday morning, U.S. troops marched from West Germany through East Germany, bound for West Berlin. Lead elements—arranged in a column of 491 vehicles and trailers carrying 1,500 men, divided into five march units—left the Helmstedt-Marienborn checkpoint at 06:34. At Marienborn, the Soviet checkpoint next to Helmstedt on the West German/East German border, US personnel were counted by guards. The column was 160 kilometres (100 mi) long, and covered 177 kilometres (110 mi) from Marienborn to Berlin in full battle gear. East German police watched from beside trees next to the autobahn all the way along.

The front of the convoy arrived at the outskirts of Berlin just before noon, to be met by Clay and Johnson, before parading through the streets of Berlin to an adoring crowd. At 04:00 on 21 August, Lyndon Johnson left a visibly reassured West Berlin in the hands of Gen. Frederick O. Hartel and his brigade of 4,224 officers and men. Every three months for the next three and a half years, a new American battalion was rotated into West Berlin; each traveled by autobahn to demonstrate Allied rights.

The creation of the wall had important implications for both German states. By stemming the exodus of people from East Germany, the East German government was able to reassert its control over the country: in spite of discontent with the wall, economic problems caused by dual currency and the black market were largely eliminated. The economy in the GDR began to grow. But, the wall proved a public relations disaster for the communist bloc as a whole. Western powers used it in propaganda as a symbol of communist tyranny, particularly after East German border guards shot and killed would-be defectors. Such fatalities were later treated as acts of murder by the reunified Germany.

Structure and adjacent areas

Layout and modifications

Position and course of the Berlin Wall and its border control checkpoints (1989)

The Berlin Wall was more than 140 kilometres (87 mi) long. In June 1962, a second, parallel fence some 100 metres (110 yd) farther into East German territory was built. The houses contained between the fences were razed and the inhabitants relocated, thus establishing what later became known as the Death Strip. The Death Strip was covered with raked sand or gravel, rendering footprints easy to notice, easing the detection of trespassers and also enabling officers to see which guards had neglected their task; it offered no cover; and most importantly, it offered clear fields of fire for the wall guards. Through the years, the Berlin Wall evolved through four versions:

  1. Wire fence (1961)
  2. Improved wire fence (1962–1965)
  3. Concrete wall (1965–1975)
  4. Grenzmauer 75 (Border Wall 75) (1975–1989)

The "fourth-generation wall", known officially as "Stützwandelement UL 12.11" (retaining wall element UL 12.11), was the final and most sophisticated version of the Wall. Begun in 1975 and completed about 1980, it was constructed from 45,000 separate sections of reinforced concrete, each 3.6 metres (12 ft) high and 1.2 metres (3.9 ft) wide, and cost 16,155,000 East German Marks or about 3,638,000 US$. The concrete provisions added to this version of the Wall were done so to prevent escapees from driving their cars through the barricades. At strategic points the wall was constructed to a somewhat weaker standard so that East German and Soviet armored vehicles could break through easily in the event of war.

The top of the wall was lined with a smooth pipe, intended to make it more difficult to scale. It was reinforced by mesh fencing, signal fencing, anti-vehicle trenches, barbed wire, dogs on long lines, "beds of nails" under balconies hanging over the "death strip", over 116 watchtowers, and 20 bunkers. This version of the Wall is the one most commonly seen in photographs, and surviving fragments of the Wall in Berlin and elsewhere around the world are generally pieces of the fourth-generation Wall. The layout came to resemble the inner German border in most technical aspects, except the Berlin Wall had no landmines and no spring-guns.

Surrounding municipalities

Besides the sector-sector boundary within Berlin itself, the wall also separated West Berlin from the present-day state of Brandenburg. The following present-day municipalities, listed in counter-clockwise direction, share a border with former West Berlin:

  • Oberhavel : Mühlenbecker Land (partially), Glienicke/Nordbahn, Hohen Neuendorf, Hennigsdorf
  • Havelland : Schönwalde-Glien, Falkensee, Dallgow-Döberitz
  • Potsdam (Urban district)
  • Potsdam-Mittelmark : Stahnsdorf, Kleinmachnow, Teltow
  • Teltow-Fläming : Großbeeren, Blankenfelde-Mahlow
  • Dahme-Spreewald : Schönefeld (partially)

Official crossings and usage

There were nine border crossings between East and West Berlin, which allowed visits by West Berliners, West Germans, Western foreigners and Allied personnel into East Berlin, as well as visits by GDR citizens and citizens of other socialist countries into West Berlin, provided that they held the necessary permits. Those crossings were restricted according to which nationality was allowed to use it (East Germans, West Germans, West Berliners, other countries). The most famous was the vehicle and pedestrian checkpoint at the corner of Friedrichstraße and Zimmerstraße, also known as Checkpoint Charlie, which was restricted to Allied personnel and foreigners.[53]

Several other border crossings existed between West Berlin and surrounding East Germany. These could be used for transit between West Germany and West Berlin, for visits by West Berliners into East Germany, for transit into countries neighbouring East Germany (Poland, Czechoslovakia, Denmark), and for visits by East Germans into West Berlin carrying a permit. After the 1972 agreements, new crossings were opened to allow West Berlin waste to be transported into East German dumps, as well as some crossings for access to West Berlin's exclaves (see Steinstücken).

Four autobahns connected West Berlin to West Germany, the most famous being the Berlin-Helmstedt autobahn, which entered East German territory between the towns of Helmstedt and Marienborn (Checkpoint Alpha), and which entered West Berlin at Dreilinden (Checkpoint Bravo for the Allied forces) in southwestern Berlin. Access to West Berlin was also possible by railway (four routes) and by boat for commercial shipping via canals and rivers.

Non-German Westerners could cross the border at Friedrichstraße station in East Berlin and at Checkpoint Charlie. When the Wall was erected, Berlin's complex public transit networks, the S-Bahn and U-Bahn, were divided with it.[48] Some lines were cut in half; many stations were shut down. Three western lines traveled through brief sections of East Berlin territory, passing through eastern stations (called Geisterbahnhöfe, or ghost stations) without stopping. Both the eastern and western networks converged at Friedrichstraße, which became a major crossing point for those (mostly Westerners) with permission to cross.

Who could cross

West Germans and citizens of other Western countries could in general visit East Germany. Usually this involved application of a visa at an East German embassy several weeks in advance. Visas for day trips restricted to East Berlin were issued without previous application in a simplified procedure at the border crossing. However, East German authorities could refuse entry permits without stating a reason. In the 1980s, visitors from the western part of the city who wanted to visit the eastern part had to exchange at least DM 25 into East German currency at the poor exchange rate of 1:1. It was forbidden to export East German currency from the East, but money not spent could be left at the border for possible future visits. Tourists crossing from the west had to also pay for a visa, which cost DM 5; West Berliners did not have to pay this.

West Berliners initially could not visit East Berlin or East Germany at all. All crossing points were closed to them between 26 August 1961 and 17 December 1963. In 1963, negotiations between East and West resulted in a limited possibility for visits during the Christmas season that year (Passierscheinregelung). Similar, very limited arrangements were made in 1964, 1965 and 1966.

In 1971, with the Four Power Agreement on Berlin, agreements were reached that allowed West Berliners to apply for visas to enter East Berlin and East Germany regularly, comparable to the regulations already in force for West Germans. However, East German authorities could still refuse entry permits.

East Berliners and East Germans could at first not travel to West Berlin or West Germany at all. This regulation remained in force essentially until the fall of the wall, but over the years several exceptions to these rules were introduced, the most significant being:

  • Elderly pensioners could travel to the West starting in 1965
  • Visits of relatives for important family matters
  • People who had to travel to the West for professional reasons (for example, artists, truck drivers, musicians, writers and so on.)

However, each visit had to be applied for individually and approval was never guaranteed. In addition, even if travel was approved, GDR travellers could exchange only a very small amount of East German Marks into Deutsche Marks (DM), thus limiting the financial resources available for them to travel to the West. This led to the West German practice of granting a small amount of DM annually (Begrüßungsgeld, or welcome money) to GDR citizens visiting West Germany and West Berlin to help alleviate this situation.

Citizens of other East European countries were in general subject to the same prohibition of visiting Western countries as East Germans, though the applicable exception (if any) varied from country to country.

Allied military personnel and civilian officials of the Allied forces could enter and exit East Berlin without submitting to East German passport controls, purchasing a visa or being required to exchange money. Likewise, Soviet military patrols could enter and exit West Berlin. This was a requirement of the post-war Four Powers Agreements. A particular area of concern for the Western Allies involved official dealings with East German authorities when crossing the border, since Allied policy did not recognize the authority of the GDR to regulate Allied military traffic to and from West Berlin, as well as the Allied presence within Greater Berlin, including entry into, exit from, and presence within East Berlin; the Allies held that only the Soviet Union, and not the GDR, had authority to regulate Allied personnel in such cases. For this reason, elaborate procedures were established to prevent inadvertent recognition of East German authority when engaged in travel through the GDR and when in East Berlin. Special rules applied to travel by Western Allied military personnel assigned to the Military Liaison Missions accredited to the commander of Soviet forces in East Germany, located in Potsdam.

Allied personnel were restricted by policy when travelling by land to the following routes:

Transit between West Germany and West Berlin
  • Road: the Helmstedt-Berlin autobahn (A2) (Checkpoints Alpha and Bravo respectively). Soviet military personnel manned these checkpoints and processed Allied personnel for travel between the two points. Military personnel were required to be in uniform when traveling in this manner.
  • Rail: Western Allied military personnel and civilian officials of the Allied forces were forbidden from using commercial train service between West Germany and West Berlin, due to the fact of GDR passport and customs controls when using them. Instead, the Allied forces operated a series of official (duty) trains that traveled between their respective duty stations in West Germany and West Berlin. When transiting the GDR, the trains would follow the route between Helmstedt and Griebnitzsee, just outside of West Berlin. In addition to persons traveling on official business, authorized personnel could also use the duty trains for personal travel on a space-available basis. The trains traveled only at night, and as with transit by car, Soviet military personnel handled the processing of duty train travelers.
Entry into and exit from East Berlin
  • Checkpoint Charlie (as a pedestrian or riding in a vehicle)

As with military personnel, special procedures applied to travel by diplomatic personnel of the Western Allies accredited to their respective embassies in the GDR. This was intended to prevent inadvertent recognition of East German authority when crossing between East and West Berlin, which could jeopardize the overall Allied position governing the freedom of movement by Allied forces personnel within all Berlin.

Ordinary citizens of the Western Allied powers, not formally affiliated with the Allied forces, were authorized to use all designated transit routes through East Germany to and from West Berlin. Regarding travel to East Berlin, such persons could also use the Friedrichstraße train station to enter and exit the city, in addition to Checkpoint Charlie. In these instances, such travelers, unlike Allied personnel, had to submit to East German border controls.

Defection attempts

During the years of the Wall, around 5,000 people successfully defected to West Berlin. The number of people who died trying to cross the wall, or as a result of the wall's existence, has been disputed. The most vocal claims by Alexandra Hildebrandt, Director of the Checkpoint Charlie Museum and widow of the Museum's founder, estimated the death toll to be well above 200. A historic research group at the Center for Contemporary Historical Research (ZZF) in Potsdam has confirmed 136 deaths. Prior official figures listed 98 as being killed.

The East German government issued shooting orders to border guards dealing with defectors, though such orders are not the same as "shoot to kill" orders. GDR officials denied issuing the latter. In an October 1973 order later discovered by researchers, guards were instructed that people attempting to cross the wall were criminals and needed to be shot: "Do not hesitate to use your firearm, not even when the border is breached in the company of women and children, which is a tactic the traitors have often used".

Early successful escapes involved people jumping the initial barbed wire or leaping out of apartment windows along the line, but these ended as the wall was fortified. East German authorities no longer permitted apartments near the wall to be occupied, and any building near the wall had its windows boarded and later bricked up. On 15 August 1961, Conrad Schumann was the first East German border guard to escape by jumping the barbed wire to West Berlin. On 22 August 1961 Ida Siekmann was the first casualty at the Berlin Wall: she died after she jumped out of her third floor apartment at 48 Bernauer Strasse. The first person to be shot and killed while trying to cross to West Berlin was Günter Litfin, a twenty-four year old tailor. He attempted to swim across the Spree Canal to freedom in West Germany on 24 August 1961, the same day that East German police had received shoot-to-kill orders to prevent anyone from escaping.

Another dramatic escape was carried out on April 1963 by Wolfgang Engels, a 19-year-old civilian employee of the Nationale Volksarmee. Engels stole a Soviet armored personnel carrier from a base where he was deployed and drove it right into the wall. He was fired at and seriously wounded by border guards. But a West German policeman intervened, firing his weapon at the East German border guards. The policeman removed Engels from the vehicle, which had become entangled in the barbed wire.

Memorial to the Victims of the Wall, with graffiti, 1982

East Germans successfully defected by a variety of methods: digging long tunnels under the wall, waiting for favorable winds and taking a hot air balloon, sliding along aerial wires, flying ultralights, and in one instance, simply driving a sports car at full speed through the basic, initial fortifications. When a metal beam was placed at checkpoints to prevent this kind of defection, up to four people (two in the front seats and possibly two in the boot) drove under the bar in a sports car that had been modified to allow the roof and windscreen to come away when it made contact with the beam. They lay flat and kept driving forward. The East Germans then built zig-zagging roads at checkpoints. The sewer system predated the wall, and some people escaped through the sewers, in a number of cases with assistance from the Girmann student group.

An airborne escape was made by Thomas Krüger, who landed a Zlin Z 42M light aircraft of the Gesellschaft für Sport und Technik, an East German youth military training organization, at RAF Gatow. His aircraft, registration DDR-WOH, was dismantled and returned to the East Germans by road, complete with humorous slogans painted on by RAF airmen such as "Wish you were here" and "Come back soon". DDR-WOH is still flying today, but under the registration D-EWOH.

If an escapee was wounded in a crossing attempt and lay on the death strip, no matter how close they were to the Western wall, Westerners could not intervene for fear of triggering engaging fire from the 'Grepos', the East Berlin border guards. The guards often let fugitives bleed to death in the middle of this ground, as in the most notorious failed attempt, that of Peter Fechter (aged 18). He was shot and bled to death, in full view of the Western media, on 17 August 1962. Fechter's death created negative publicity worldwide that led the leaders of East Berlin to place more restrictions on shooting in public places, and provide medical care for possible “would-be escapers”. The last person to be shot while trying to cross the border was Chris Gueffroy on 6 February 1989.

The Wall gave rise to a widespread sense of desperation and oppression in East Berlin, as expressed in the private thoughts of one resident, who confided to her diary "Our lives have lost their spirit…we can do nothing to stop them."

"Mr. Gorbachev, tear down this wall."

Ronald Reagan at the Berlin Wall, June 1987: “Tear down this wall!
In a speech at the Brandenburg Gate commemorating the 750th anniversary of Berlin on 12 June 1987, Ronald Reagan challenged Mikhail Gorbachev, then the General Secretary of the Communist Party of the Soviet Union, to tear down the wall as a symbol of increasing freedom in the Eastern Bloc:
We welcome change and openness; for we believe that freedom and security go together, that the advance of human liberty can only strengthen the cause of world peace. There is one sign the Soviets can make that would be unmistakable, that would advance dramatically the cause of freedom and peace. General Secretary Gorbachev, if you seek peace, if you seek prosperity for the Soviet Union and eastern Europe, if you seek liberalization, come here to this gate. Mr. Gorbachev, open this gate. Mr. Gorbachev, tear down this wall!

The Fall

After allowing for loopholes throughout the summer, Hungary effectively disabled its physical border defenses with Austria on 19 August 1989 and, in September, more than 13,000 East German tourists escaped through Hungary to Austria. This set up a chain of events. The Hungarians prevented many more East Germans from crossing the border and returned them to Budapest. These East Germans flooded the West German embassy and refused to return to East Germany. The East German government responded by disallowing any further travel to Hungary, but allowed those already there to return. This triggered a similar incident in neighboring Czechoslovakia. On this occasion, the East German authorities allowed them to leave, providing that they used a train which transited East Germany on the way. This was followed by mass demonstrations within East Germany itself. (See Monday demonstrations in East Germany.) The longtime leader of East Germany, Erich Honecker, resigned on 18 October 1989 and was replaced by Egon Krenz a few days later. Honecker had predicted in January of that year that the wall would stand for a 50 or 100 more years if the conditions that had caused its construction did not change.

Protest demonstrations broke out all over East Germany in September 1989. Initially, protesters were mostly people wanting to leave to the West, chanting "Wir wollen raus!" ("We want out!"). Then protestors began to chant "Wir bleiben hier", ("We're staying here!"). This was the start of what East Germans generally call the "Peaceful Revolution" of late 1989. The protest demonstrations grew considerably by early November. The movement neared its height on 4 November when half a million people gathered at the Alexanderplatz demonstration, a rally for change in East Berlin's large public square and transportation hub. (Henslin, 07)

Meanwhile, the wave of refugees leaving East Germany for the West had increased and had found its way through Hungary via Czechoslovakia (or via the West German Embassy in Prague), tolerated by the new Krenz government and in agreement with the communist Czechoslovak government. To ease the complications, the politburo led by Krenz decided on 9 November to allow refugees to exit directly through crossing points between East Germany and West Germany, including West Berlin. On the same day, the ministerial administration modified the proposal to include private travel. The new regulations were to take effect on 17 November 1989.

Günter Schabowski, a spokesperson for the politburo, had the task of announcing this; however he had not been involved in the discussions about the new regulations and had not been fully updated. Shortly before a press conference on 9 November, he was handed a note that said that East Berliners would be allowed to cross the border with proper permission but given no further instructions on how to handle the information. These regulations had only been completed a few hours earlier and were to take effect the following day, so as to allow time to inform the border guards—however, nobody had informed Schabowski. He read the note out loud at the end of the conference. When the Italian journalist Riccardo Ehrman, the Berlin correspondent of ANSA newsagency, asked when the regulations would come into effect, Schabowski assumed it would be the same day based on the wording of the note and replied "As far as I know effective immediately, without delay". After further questions from journalists he confirmed that the regulations included the border crossings towards West Berlin, which he had not mentioned until then.

Walking through Checkpoint Charlie, 10 November 1989

Soon afterwards, a West German television channel, ARD, broadcast incomplete information from Schabowski's press conference. A moderator stated: "This ninth of November is a historic day." "East Germany has announced that, starting immediately, its borders are open to everyone."

After hearing the broadcast, East Germans began gathering at the wall, demanding that border guards immediately open its gates. The surprised and overwhelmed guards made many hectic telephone calls to their superiors about the problem, but it became clear that no one among the East German authorities would take personal responsibility for issuing orders to use lethal force, so the vastly outnumbered soldiers had no way to hold back the huge crowd of East German citizens. In face of the growing crowd, the guards finally yielded, opening the checkpoints and allowing people through with little or no identity checking. Ecstatic East Berliners were soon greeted by West Berliners on the other side in a celebratory atmosphere.

Demolition

The date on which the Wall fell is considered to have been 9 November 1989 but the Wall in its entirety was not torn down immediately. Starting that evening and in the days and weeks that followed, people came to the wall with sledgehammers or otherwise hammers and chisels to chip off souvenirs, demolishing lengthy parts of it in the process and creating several unofficial border crossings. These people were nicknamed "Mauerspechte" (wall woodpeckers).

The East German regime announced the opening of ten new border crossings the following weekend, including some in historically significant locations (Potsdamer Platz, Glienicker Brücke, Bernauer Straße). Crowds on both sides waited there for hours, cheering at the bulldozers which took parts of the Wall away to reinstate old roads. Photos and television footage of these events is sometimes mislabelled "dismantling of the Wall", even though it was merely the construction of new crossings. New border crossings continued to be opened through the middle of 1990, including the Brandenburg Gate on 22 December 1989.

West Germans and West Berliners were allowed visa-free travel starting 23 December. Until then, they could only visit East Germany and East Berlin under restrictive conditions that involved application for a visa several days or weeks in advance and obligatory exchange of at least 25 DM per day of their planned stay, all of which hindered spontaneous visits. Thus, in the weeks between 9 November and 23 December, East Germans could actually travel more freely than Westerners.

Almost all of the remaining sections of Berlin Wall were rapidly chipped away. Photo December 1990

Television coverage of citizens demolishing sections of the wall on the evening of 9 November and the new border crossings opened weeks later, led some foreigners to think the Wall was torn down quickly. Technically, the Wall remained guarded for some time after 9 November, though at a decreasing intensity. In the first months, the East German military even tried to repair some of the damages done by the "wall peckers". Gradually these attempts ceased, and guards became more lax, tolerating the increasing demolitions and "unauthorized" border crossing through the holes. On 13 June 1990, the official dismantling of the Wall by the East German military began in Bernauer Straße. On 1 July, the day East Germany adopted the West German currency, all de jure border controls ceased, although the inter-German border had become meaningless for some time before that. The dismantling continued to be carried out by military units (after unification under the Bundeswehr) and lasted until November 1991. Only a few short sections and watchtowers were left standing as memorials.

The fall of the Wall was the first step toward German reunification, which was formally concluded on 3 October 1990.

Opposition

In some European capitals at the time there was a deep anxiety over prospects for a reunified Germany. In September 1989, British Prime Minister Margaret Thatcher pleaded with Soviet President Mikhail Gorbachev not to let the Berlin Wall fall and confided that she wanted the Soviet leader to do what he could to stop it.

"We do not want a united Germany. This would lead to a change to postwar borders and we cannot allow that because such a development would undermine the stability of the whole international situation and could endanger our security", Thatcher told Gorbachev.

After the fall of the Berlin Wall, French President François Mitterrand warned Thatcher that a unified Germany could make more ground than Adolf Hitler ever had and that Europe would have to bear the consequences.

Celebrations

On 25 December 1989, Leonard Bernstein gave a concert in Berlin celebrating the end of the Wall, including Beethoven's 9th symphony (Ode to Joy) with the word "Joy" (Freude) changed to "Freedom" (Freiheit) in the lyrics sung. The orchestra and choir were drawn from both East and West Germany, as well as the United Kingdom, France, the Soviet Union, and the United States.

Roger Waters performed the Pink Floyd album The Wall just north of Potsdamer Platz on 21 July 1990, with guests including Bon Jovi, Scorpions, Bryan Adams, Sinéad O'Connor, Thomas Dolby, Joni Mitchell, Marianne Faithfull, Levon Helm, Rick Danko and Van Morrison. David Hasselhoff performed his song "Looking for Freedom", which was very popular in Germany at that time, standing on the Berlin wall.

Over the years, there has been a repeated controversial debate whether 9 November would make a suitable German national holiday, often initiated by former members of political opposition in East Germany such as Werner Schulz. Besides being the emotional apogee of East Germany's peaceful revolution, 9 November is also the date of the end of the Revolution of 1848 and the date of the 1918 abdication of Kaiser Wilhelm II and declaration of the Weimar Republic, the first German republic. However, 9 November is also the anniversary of the 1923 Beer Hall Putsch and the infamous Kristallnacht pogroms of the Nazis in 1938. Nobel Laureate Elie Wiesel criticized the first euphoria, noting that "they forgot that 9 Nov. has already entered into history—51 years earlier it marked the Kristallnacht." As reunification was not official and complete until 3 October, that day was finally chosen as German Unity Day.

20th Anniversary Celebrations

On 9 November 2009, Berlin celebrated the 20th Anniversary of the Fall of the Berlin Wall with a "Festival of Freedom" with dignitaries from around the world in attendance for an evening celebration around the Brandenburg Gate. A high point was when over 1,000 colourfully designed foam domino tiles, each over 8 feet (2.4 m) tall, that were stacked along the former route of the wall in the city center were toppled in stages, converging in front of the Brandenburg Gate.

A Berlin Twitter Wall was set up to allow Twitter users to post messages commemorating the 20th anniversary. Masses of Chinese users have used it to protest the Great Firewall of China. Berlin Twitter Wall was quickly blocked by the Chinese authorities.

In the United States, the German Embassy coordinated a public diplomacy campaign with the motto "Freedom Without Walls", to commemorate the 20th anniversary of the fall of the Berlin Wall. The campaign was focused on promoting awareness of the fall of the Berlin Wall among current college students. Students at over 30 universities participated in "Freedom Without Walls" events in late 2009. First place winner of the Freedom Without Walls Speaking Contest Robert Cannon received a free trip to Berlin for 2010.

An international project called Mauerreise (Journey of the Wall) took place in various countries. Twenty symbolic wall bricks were sent from Berlin starting in May 2009. Their destination: Korea, Cyprus, Yemen and other places where everyday life is characterised by division and border experience. In these places, the bricks will become a blank canvas for artists, intellectuals and young people to tackle the 「wall」 phenomenon.

To commemorate the 20th Anniversary of the Fall of the Berlin Wall, Twinity reconstructed a true-to-scale section of the wall in virtual Berlin. The MTV Europe Music Awards, on the 5 November, had U2 and Tokio Hotel perform songs dedicated to, and about the Berlin Wall. U2 performed at the Brandenburg Gate, and Tokio Hotel performed "World Behind My Wall".

Palestinians in the town of Kalandia, West Bank pulled down parts of the Israeli West Bank barrier, in a demonstration marking the 20th Anniversary of the Fall of the Berlin Wall.

The International Spy Museum in Washington DC hosted a Trabant car rally where 20 Trabants gathered in recognition of the 20th anniversary of the fall of the Berlin Wall. Rides were raffled every half hour and a Trabant crashed through a Berlin Wall mock up. The Trabant was the East German people's car that many used to leave DDR after the collapse.

The Allied Museum in the Dahlem district of Berlin hosted a number of events to mark the Twentieth Anniversary of the Fall of the Berlin Wall. The museum held a Special Exhibition entitled "Wall Patrol – The Western Powers and the Berlin Wall 1961–1990" which focused on the daily patrols deployed by the Western powers to observe the situation along the Berlin Wall and the fortifications on the GDR border.

Hill, the author of Voices Under Berlin, was presented to the Museum by David Guerra, Berlin veteran and webmaster of the site www.berlinbrigade.com. The stamps splendidly illustrate that even twenty years on, veterans of service in Berlin still regard their service there as one of the high points of their lives.

Legacy

Little is left of the Wall at its original site, which was destroyed almost everywhere. Three long sections are still standing: an 80-metre (263 ft) piece of the first (westernmost) wall at the Topography of Terror, site of the former Gestapo headquarters, half way between Checkpoint Charlie and Potsdamer Platz; a longer section of the second (easternmost) wall along the Spree River near the Oberbaumbrücke, nicknamed East Side Gallery; and a third section that is partly reconstructed, in the north at Bernauer Straße, which was turned into a memorial in 1999. Some other isolated fragments and a few watchtowers also remain in various parts of the city.

None still accurately represents the Wall's original appearance. They are badly damaged by souvenir seekers. Fragments of the Wall were taken and some were sold around the world. Appearing both with and without certificates of authenticity, these fragments are now a staple on the online auction service eBay as well as German souvenir shops. Today, the eastern side is covered in graffiti that did not exist while the Wall was guarded by the armed soldiers of East Germany. Previously, graffiti appeared only on the western side. Along the tourist areas of the city centre, the city government has marked the location of the former wall by a row of cobblestones in the street. In most places only the "first" wall is marked, except near Potsdamer Platz where the stretch of both walls is marked, giving visitors an impression of the dimension of the barrier system.

Museum

15 years after the fall, a private museum rebuilt a 200-metre (656 ft) section close to Checkpoint Charlie, although not in the location of the original wall. They temporarily erected more than 1,000 crosses in memory of those who died attempting to flee to the West. The memorial was installed in October 2004 and demolished in July 2005.

Cultural differences

For many years after reunification, people in Germany talked about cultural differences between East and West Germans (colloquially Ossis and Wessis), sometimes described as Mauer im Kopf (The wall in the head). A September 2004 poll found that 25 percent of West Germans and 12 percent of East Germans wished that East and West should be separated again by a "Wall".A poll taken in October 2009 on the occasion of the 20th anniversary of the fall of the wall indicated, however, that only about a tenth of the population was still unhappy with the unification (8 percent in the East; 12 percent in the West). Although differences are still perceived between East and West, Germans make similar distinctions between North and South.

A recent poll conducted by Russia's VTsIOM, found that more than half of all Russians do not know who built the Berlin Wall. Ten percent of people surveyed thought Berlin residents built it themselves. Six percent said Western powers built it and four percent thought it was a "bilateral initiative" of the Soviet Union and the West. Fifty-eight percent said they did not know who built it, with just 24 percent correctly naming the Soviet Union and its then-communist ally East Germany.

Wall segments around the world

Not all segments of the wall were ground up as the wall was being torn down. Many segments have been given to various institutions around the world. They can be found, for instance in presidential and historical museums, lobbies of hotels and corporations, at universities and government buildings, and in public spaces around the world
