The Berlin Wall, which physically and ideologically divided East and West Berlin, was constructed in 1961. This wall became a powerful symbol of the Cold War, representing the divide between the communist East and the democratic West. It not only separated families and friends but also epitomized the broader geopolitical tensions between the Soviet Union and the United States. The wall fell in 1989, marking a pivotal moment in history that led to the reunification of Germany and a significant decline in Cold War hostilities, symbolizing the victories of democratic movements over authoritarian regimes.
