On the night of 20th of August 1968, USSR (Union of Soviet Socialist Republics) President Brezhnev sent an invasion force of 500,000 troops from Warsaw Pact countries into Czechoslovakia.
Months earlier the people of Czechoslovakia had embraced The Prague Spring electing Alexander Dubček building upon the movement emanating from the Writer’s Congress to introduce reforms to the country.
The Czechs at first employed peaceful protest tactics – standing in front of tanks and offering flowers to soldiers. The student activist, Jan Palach, burned himself to death in Prague’s Wenceslas Square. Dubcek was arrested and taken to Moscow. The pro-Soviet, Gustav Husak, was installed as the Czech leader in a puppet administration. Husak reversed Dubcek’s reforms and Czechoslovakia remained a communist country inside the Warsaw Pact.
