1989: Opening of the Berlin Wall
9 November All day
“On November 9, 1989, as the Cold War began to thaw across Eastern Europe, the spokesman for East Berlin’s Communist Party announced a change in his city’s relations with the West. Starting at midnight that day, he said, citizens of the GDR were free to cross the country’s borders. East and West Berliners flocked to the wall, drinking beer and champagne and chanting “Tor auf!” (“Open the gate!”). At midnight, they flooded through the checkpoints. More than 2 million people from East Berlin visited West Berlin that weekend.
The reunification of East and West Germany was made official on October 3, 1990, almost one year after the fall of the Berlin Wall.”The Berlin Wall: The Fall of the Wall
