The document summarizes key events of the Hungarian Revolution of 1956. It describes how Hungarians initially welcomed the Soviet Union after World War 2 but soon faced totalitarian rule under Stalinist policies. Reforms in the 1950s raised living standards but unrest grew. Mass protests in October 1956 against the communist government grew into a full revolution as protesters took control of Budapest. The revolution succeeded initially in toppling the government and Soviet troops withdrew, but the Soviet Union soon reasserted control, arresting and executing opposition leaders and forcing Imre Nagy from power. Hundreds of thousands of Hungarians fled as refugees in the revolution's bloody aftermath.
