when did the berlin wall start to come down
Berlin Wall The Berlin Wall (German: Berliner Mauer) was a guarded concrete barrier that physically and ideologically divided Berlin from 1961 to 1989.[1] Constructed by the German Democratic Republic (GDR, East Germany), starting on 13 August 1961, the Wall completely cut off (by land) West Berlin from surrounding East Germany and from East Berlin until government officials opened it in November 1989.[2] Its demolition officially began on 13 June 1990 and finished in 1992.[3] The barrier included guard towers placed along large concrete walls,[4] accompanied by a wide area (later known as the "death strip") that contained anti-vehicle trenches, "fakir beds" and other defenses. The Eastern Bloc portrayed the Wall as protecting its population from fascist elements conspiring to prevent the "will of the people" in building a socialist state in East Germany. In practice, the Wall served to prevent the massive emigration and defection that had marked East Germany and the communist Eastern Bloc during the post-World War II period.

East Germany Geographically, the German Democratic Republic bordered the Baltic Sea to the north; Poland to the east; Czechoslovakia to the southeast and West Germany to the southwest and west. Internally, the GDR also bordered the Soviet sector of Allied-occupied Berlin, known as East Berlin, which was also administered as the state's de facto capital. It also bordered the three sectors occupied by the United States, United Kingdom and France known collectively as West Berlin. The three sectors occupied by the Western nations were sealed off from the rest of the GDR by the Berlin Wall from its construction in 1961 until it was brought down in 1989.
