The Berlin Wall (German: Berliner Mauer) was a barrier that divided Berlin from 1961 to 1989, constructed by the German Democratic Republic (GDR, East Germany) starting on 13 August 1961, that completely cut off (by land) West Berlin from surrounding East Germany and from East Berlin until it was opened in November 1989. The Berlin Wall was officially referred to as the "Anti-Fascist Protection Rampart" (German: Antifaschistischer Schutzwall) by GDR authorities, implying that the NATO countries and West Germany in particular were "fascists."The West Berlin city government sometimes referred to it as the "Wall of Shame"—a term coined by mayor Willy Brandt—while condemning the Wall's restriction on freedom of movement. Along with the separate and much longer Inner German border (IGB), which demarcated the border between East and West Germany, it came to symbolize the "Iron Curtain" that separated Western Europe and the Eastern Bloc during the Cold War.
