Hungarian Revolution of 1956 [SEP] Introduction
The Hungarian Revolution of 1956 (), or the Hungarian Uprising, was a nationwide revolution against the Hungarian People's Republic and its Soviet-imposed policies, lasting from 23 October until 10 November 1956. Leaderless at the beginning, it was the first major threat to Soviet control since the Red Army drove Nazi Germany from its territory at the End of World War II in Europe. The revolt began as a student protest, which attracted thousands as they marched through central Budapest to the Hungarian Parliament building, calling out on the streets using a van with loudspeakers. A student delegation, entering the radio building to try to broadcast the students' demands, was detained.
