On June 17, 1953, the Soviet Union orders an entire armored division of its troops into East Berlin to crush a rebellion by East German workers and antigovernment protesters. The Soviet assault set a precedent for later interventions into Hungary in 1956 and Czechoslovakia in 1968.
The riots in East Berlin began among construction workers, who took to the streets a day earlier to protest an increase in work schedules by the communist government of East Germany. By the next day, the crowd of disgruntled workers and other antigovernment dissidents had grown to between 30,000 and 50,000. Leaders of the protest issued a call for a general strike, the resignation of the communist East German government and free elections.
