Cold War: Fall of the Berlin Wall: East Germany opens checkpoints in the Berlin Wall, allowing its citizens to travel to West Berlin.

The Berlin Wall fell on 9 November 1989 during the Peaceful Revolution, marking the beginning of the destruction of the figurative Iron Curtain, as East Berlin transit restrictions were overwhelmed and discarded. Sections of the wall were breached, and planned deconstruction began the following June. It was one of the series of events that started the fall of communism in Central and Eastern Europe. The fall of the inner German border took place shortly afterward. An end to the Cold War was declared at the Malta Summit in early December, and German reunification took place in October the following year.

East Germany, officially known as the German Democratic Republic (GDR), was a country in Central Europe from its formation on 7 October 1949 until its reunification with West Germany (FRG) on 3 October 1990. Until 1989, it was generally viewed as a communist state and described itself as a socialist "workers' and peasants' state". The economy of the country was centrally planned and state-owned. Although the GDR had to pay substantial war reparations to the Soviets, its economy became the most successful in the Eastern Bloc.

A border checkpoint is a location on an international border where travelers or goods are inspected and allowed passage through. Authorization often is required to enter a country through its borders. Access-controlled borders often have a limited number of checkpoints where they can be crossed without legal sanctions. Arrangements or treaties may be formed to allow or mandate less restrained crossings. Land border checkpoints can be contrasted with the customs and immigration facilities at seaports, international airports, and other ports of entry.

The Berlin Wall was a guarded concrete barrier that encircled West Berlin from 1961 to 1989, separating it from East Berlin and the German Democratic Republic. Construction of the Berlin Wall was commenced by the government of the GDR on 13 August 1961. It included guard towers placed along large concrete walls, accompanied by a wide area that contained anti-vehicle trenches, beds of nails and other defenses. The primary intention for the Wall's construction was to prevent East German citizens from fleeing to the West.
