End of the Wall and United Germany
From the late 1980s, the Cold War was coming to an end. Starting with the policies of the communist General Secretary Mikhail Gorbachev, reform movements in the Soviet Union gained momentum. In 1989, even the Berlin Wall was to become history. After a news report on freedom of travel was ambiguously processed, East Berliners streamed en masse to the Wall in a November night and brought it down in a peaceful revolution. The Soviet Union officially existed until 1991, but with the fall of the Wall, the end of the Cold War was sealed. As early as 1990, Germany was united. By the way, during the Cold War, Berlin was indeed the capital of the GDR, but in West Germany it was instead the comparatively small Bonn in North Rhine-Westphalia. Only on October 3, 1990, Berlin again became the capital of a united Germany.
