Checkpoint Charlie (or "Checkpoint C") was the best-known Berlin Wall crossing point between East Berlin and West Berlin during the Cold War (1947–1991), as named by the Western Allies.
East German leader Walter Ulbricht agitated and maneuvered to get the Soviet Union's permission to construct the Berlin Wall in 1961 to stop emigration and defection westward through the Border system, preventing escape across the city sector border from East Berlin into West Berlin.
