The event that reshaped the European political landscape in 1989 was the fall of the Berlin Wall. The wall, which had divided East and West Berlin since its construction in 1961, symbolized the broader divide between the communist East and the democratic West during the Cold War. Its fall on November 9, 1989, marked not only the end of a physical barrier but also heralded the collapse of communist regimes across Eastern Europe. This monumental event set the stage for German reunification and significant political changes across Europe, ultimately contributing to the end of the Cold War.
