Premise: The Berlin Wall ( Berliner Mauer ) was a guarded concrete barrier that physically and ideologically divided Berlin from 1961 to 1989 . 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 .
Hypothesis: The Berlin Wall signified the physical border between Western Europe and the Eastern Bloc after World War II.
