Which major event in 1989 symbolized the conclusion of the Cold War?

The fall of the Berlin Wall in 1989 is widely regarded as a pivotal event that symbolized the conclusion of the Cold War. The wall, erected in 1961, physically and ideologically divided East and West Berlin, representing the broader divide between the communist East and the democratic West. Its destruction marked a significant moment in history, as it not only facilitated the reunification of Germany but also signified the weakening of communist control in Eastern Europe. The events surrounding the wall's fall were part of a larger wave of revolutions in Eastern Europe that led to the collapse of communist governments across the region. This seismic shift fundamentally altered the geopolitical landscape and led to the eventual dissolution of the Soviet Union in 1991, effectively closing the chapter on the Cold War era.
