In GCSE History students will look at the Cold War, which lasted from the end of World War II until the fall of the Soviet Union. One aspect of the Cold War they will cover will be the Warsaw Pact invasion of Czechoslovakia in 1968.
In 1968 the Soviet Union led a Warsaw Pact invasion of Czechoslovakia, in order to bring to an end the reforms introduced by the new government. They feared that the virus of reform could spread to other communist countries, and that Czechoslovakia could leave the Warsaw Pact and join NATO instead. The invasion guaranteed that that would not happen.
