The Wall, built by the communist authorities of East Berlin, divided the city between 1961 and 1989 and became the iconic symbol on the Cold War. East Germany was under communist and Soviet control from its founding as the German Democratic Republic (DDR) in 1949 and ceased to exist following German reunification in 1990.
