The Prague Spring of 1968 marked a brief period of liberalization in Czechoslovakia under Alexander Dubček's leadership. This movement aimed to create "socialism with a human face" through political, economic, and social reforms, challenging Soviet control over the Eastern Bloc. However, the Soviet Union and its Warsaw Pact allies viewed these reforms as a threat. In August 1968, they invaded Czechoslovakia, suppressing the Prague Spring and restoring orthodox communist rule. This event had lasting impacts on Cold War dynamics and the communist world.
