        Third Reich (1933–45). Berlin in the 1920s was the third largest municipality in the world. 
        After World War II, the city became divided into East Berlin -- the capital of 
        East Germany -- and West Berlin, a West German exclave surrounded by the Berlin Wall 
        from 1961–89. Following German reunification in 1990, the city regained its status 
        as the capital of Germany, hosting 147 foreign embassies."
