The famous wall that divided a city into East and West from 1961 to 1989 is the Berlin Wall. Erected by East Germany on August 13, 1961, the wall served as a physical and ideological barrier between East Berlin, a communist state, and West Berlin, which was democratic and capitalist. The Berlin Wall symbolized the Cold War divide not just in Germany but globally, representing the conflict between the Eastern Bloc and the Western powers. Its fall on November 9, 1989, marked a significant moment in history, heralding the end of the Cold War and leading toward the reunification of Germany and the collapse of communist regimes in Eastern Europe.
