August 21, 1968
The Czechoslovakian people spontaneously and nonviolently resisted invasion of their country by hundreds of thousands of troops and more than 5,000 tanks from the Soviet Union and four other Warsaw Pact countries. The troops were enforcing the overthrow and arrest of Alexander Dubcek and his government. They had been implementing significant democratic reforms known collectively as “socialism with a human face,” or the Prague Spring.
