Slovakia
The territory of Czechoslovakia was liberated by the Soviet Union at the end of World War II in 1945. After the liberation, Czechoslovakia was reunified and briefly existed as a democratic country. The Communist Party successfully performed a state coup in 1948 and ruled Czechoslovakia as a totalitarian one-party state which was a satellite of the Soviet Union. In 1989, the one-party rule of the Communist Party was overthrown during the Velvet Revolution, which was a series of large and peaceful demonstrations by the citizens in the streets.
