2. The Fall of the Berlin Wall (1989)
The Berlin Wall, erected in 1961, stood as a formidable barrier dividing East and West Berlin for 28 years. On November 9, 1989, an unexpected announcement by East German official Günter Schabowski led to masses of East Germans gathering at border crossings, overwhelming guards who, unprepared and unwilling to use force, opened the gates. This unprecedented event symbolized the end of the Cold War and paved the way for German reunification. (dw.com)
