The Prague Spring took place in 1968. This was a period of political liberalization and reform in Czechoslovakia under the leadership of Alexander Dubček. Dubček aimed to create "socialism with a human face," promoting freedom of the press, speech, and other civil liberties. However, this movement was met with resistance from the Soviet Union and its allies. In August 1968, Warsaw Pact troops invaded Czechoslovakia, effectively ending the reforms. The Prague Spring represents a significant moment in Cold War history, reflecting tensions between Soviet authority and calls for greater autonomy within Eastern Bloc nations.
