Prague Spring Crushed

Setting the scene

The Prague Spring was crushed on August 20-21, 1968, when 500,000 Warsaw Pact troops—primarily Soviet, with Polish, Hungarian, Bulgarian, and East German units—invaded Czechoslovakia to end liberal reforms. The Prague Spring began in January 1968 when Alexander Dubček became Communist Party leader and introduced 'socialism with a human face'—ending censorship, allowing freedom of speech and travel, and planning democratic reforms within a socialist framework.

What happened

The invasion involved 6,500 tanks. Czechs offered nonviolent resistance—removing street signs, arguing with soldiers, and broadcasting appeals. One student, Jan Palach, later self-immolated in protest. The Soviets arrested Dubček and flew him to Moscow, where he was forced to sign the Moscow Protocol reversing reforms. Dubček was replaced in April 1969 by Gustáv Husák, who instituted 'normalization'—purging reformers and restoring hardline rule.

Why it still matters

The crushing of the Prague Spring demonstrated the Brezhnev Doctrine—that the USSR would not allow any socialist state to leave the bloc or liberalize. It crushed hopes for reform in Eastern Europe for 20 years and disillusioned Western leftists. The invasion showed that Soviet control rested on force, not ideology. The Prague Spring's ideas resurfaced in 1989 during the Velvet Revolution, which peacefully overthrew communism. The 1968 invasion remains a symbol of Soviet imperialism and the struggle for freedom in Eastern Europe.

Background

Brezhnev justified limited sovereignty.
