Fall of the Berlin Wall (1989)
The Berlin Wall fell during the Peaceful Revolution when East German officials mistakenly announced immediate border openings at a press conference. At 10:45 PM, overwhelmed guards opened checkpoints at Bornholmer Straße. East Berliners flooded into West Berlin, greeted by crowds with flowers and champagne. The 28-year-old barrier dividing Communist East from Democratic West crumbled, symbolizing the Cold War's end.
