The invasion, known as Operation Danube, led to almost half a million soldiers crossing the border to bring Alexander Dubček's reforms to an end.

The Prague Spring began in early January, shortly after Dubček became the leader of Czechoslovakia. Keen to push forward with de-Stalinisation within the country, he granted greater freedom to the press and introduced a programme of ‘socialism with a human face’ by which he intended to decentralise parts the economy and introduce some limited democratic reforms.

This new openness saw open criticisms of the Czechoslovakian government begin to appear in the press, which concerned the other Warsaw Pact countries. János Kádár, the leader of Hungary who came to power after the fall of Imre Nagy in 1956, even warned that the situation in Czechoslovakia seemed "similar to the prologue of the Hungarian counterrevolution".

Concerned that Dubček's reforms might spread to other Eastern Bloc countries and threaten the USSR’s security, the Soviet leader Brezhnev chose to open negotiations with the Czechoslovakian leadership that lasted into August. The talks ended in compromise, but Brezhnev continued to be unhappy with the situation and began to prepare military intervention.

Overwhelmed by the military invasion, Dubček asked his people not to resist. 72 Czech and Slovak soldiers and 108 civilians were killed, with a further 500 civilians injured. It later emerged that members of the Czechoslovakian government had asked for Soviet assistance against Dubček’s reforms.
