The Berlin Wall was a concrete barrier that divided East and West Berlin from August 13, 1961, until November 9, 1989, symbolizing the division of East and West Germany and the broader ideological conflict between communism and democracy during the Cold War. Its construction was a response to the mass emigration of East Germans to the West, as well as a way for the Soviet-backed East German government to prevent further defections. The fall of the Berlin Wall marked a pivotal moment in the decline of communism in Eastern Europe and the eventual end of the Cold War.
