The Berlin Wall

The Berlin Wall (German: Berliner Mauer) was a physical barrier separating West Berlin from the German Democratic Republic (GDR) (East Germany), including East Berlin. The longer inner German border demarcated the border between East and West Germany. Both borders came to symbolize the Iron Curtain between Western and Eastern Europe.
The wall separated East Germany from West Germany for more than 25 years, from the day construction began on August 13, 1961 until it was opened on November 9th, 1989.[1]
During this period, at least 136 people were confirmed killed trying to cross the Wall into West Berlin, according to official figures. However, a prominent victims' group claims that more than 200 people were killed trying to flee from East to West Berlin.[2] The East German government issued shooting orders to border guards dealing with defectors; such orders are not the same as shoot to kill orders which GDR officials denied ever issuing.[3]
When the East German government announced on November 9, 1989, after several weeks of civil unrest, that all GDR citizens could visit West Germany and West Berlin, crowds of East Germans climbed onto and crossed the wall, joined by West Germans on the other side in a celebratory atmosphere. Over the next few weeks, parts of the wall were chipped away by a euphoric public and by souvenir hunters; industrial equipment was later used to remove almost all of the rest of it.
The fall of the Berlin Wall paved the way for German reunification, which was formally concluded on October 3, 1990.
Celebrations

On December 25, 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 text 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.[18]
Roger Waters performed the Pink Floyd album The Wall in Potsdamer Platz on 21 July 1990, with guests including 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.
Some[who?] believe November 9 would have made a suitable German national holiday, since it both marks the emotional apogee of East Germany's peaceful revolution and is also the date of the declaration of the first German republic, the Weimar Republic, in 1918. However, November 9 is also the anniversary of the 1923 Beer Hall Putsch and the infamous Kristallnacht pogroms of 1938 and, therefore, October 3 was chosen instead. Part of this decision was that the East German government wanted to conclude reunification before East Germany could celebrate a 41st anniversary on October 7, 1990.
