Czechoslovakian Uprising (1968)
This uprising, which is also referred to as the Prague Spring of 1968, was another rebellion caused by discontent with Soviet policies, this time in Czechoslovakia. This was another instance of a country under Soviet Control struggling to break free and form a more capitalistic, democratic government.
The rebellion began with the election of Alexander Dubek on the 5th of January. Dubek made many reforms in an effort to decentralize the economy and democratize Czechoslovakia. He loosed restrictions on freedom of speech, media, and travel. He oversaw the decision to split into the Czech Republic and the Slovakia Republic, which was the only reform to last after the end of the Prague Spring.
The reforms were received badly by Soviet leaders. After failed negociations, they sent thousands of Warsaw Pact troops and tanks to occupy the country. There were a multitude of non-violent protests, but no real military resistance. Czechoslovakia remained pccupied until 1991.
