The Berlin Wall was officially referred to as the "Anti-Fascist Protective Wall" (German: Antifaschistischer Schutzwall) by GDR authorities, implying that the NATO countries and West Germany in particular were considered equal to "fascists"[5] by GDR propaganda. 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 a physical marker of the "Iron Curtain" that separated Western Europe and the Eastern Bloc during the Cold War.
