On June 12, 1987, in one of his most famous Cold War speeches, President Ronald Reagan challenges Soviet Leader Mikhail Gorbachev to “tear down” the Berlin Wall, a symbol of the repressive Communist era in a divided Germany.
In 1945, following Germany’s defeat in World War II, the nation’s capital, Berlin, was divided into four sections, with the Americans, British and French controlling the western region and the Soviets gaining power in the eastern region. In May 1949, the three western sections came together as the Federal Republic of Germany (West Germany), with the German Democratic Republic (East Germany) being established in October of that same year. In 1952, the border between the two countries was closed and by the following year East Germans were prosecuted if they left their country without permission. In August 1961, the Berlin Wall was erected by the East German government to prevent its citizens from escaping to the West. Between 1949 and the wall’s inception, it’s estimated that over 2.5 million East Germans fled to the West in search of a less repressive life.
