The Berlin Wall was built in 1961 by East Germany to prevent its citizens from fleeing to West Berlin and West Germany due to economic and political conditions. It divided the city into East and West for 28 years. In 1989, large protests in East Germany grew and the government was forced to open the border, eventually dismantling the Wall by 1991 to reunify Germany. The fall of the Berlin Wall ended the Cold War and Communist control in Eastern Europe.
