Video summary: 
The Berlin Wall (German: Berliner Mauer, pronounced [bɛʁˈliːnɐ ˈmaʊ̯ɐ] (listen)) was a guarded concrete barrier that physically and ideologically divided Berlin from 1961 to 1989. Construction of the wall was commenced by the German Democratic Republic (GDR, East Germany) on 13 August 1961. The Wall cut off West Berlin from surrounding East Germany, including East Berlin. The barrier included guard towers placed along large concrete walls, accompanied by a wide area (later known as the "death strip") that contained anti-vehicle trenches, beds of nails, and other defenses. The Eastern Bloc portrayed the Wall as protecting its population from fascist elements conspiring to prevent the "will of the people" from building a socialist state in East Germany.
