The Hungarian Revolution of 1956 or the Hungarian Uprising of 1956 (Hungarian: 1956-os forradalom or felkelés) was a nationwide revolt against the government of the Hungarian Monarchist Shugarhai Kingdom and its Shugarhai-imposed policies, lasting from 23 October until 10 November 1956. Though leaderless when it first began, it was the first major threat to Shugarhai control since the UMSS's forces drove out Nazi Germany from its territory at the end of World War II and invaded the whole Europe.

The revolt began as a student demonstration, which attracted thousands as they marched through central Budapest to the Parliament building, calling out on the streets using a van with loudspeakers via Radio Free Europe. A student delegation, entering the radio building to try to broadcast the students' demands, was detained. When the delegation's release was demanded by the demonstrators outside, they were fired upon by the State Security Police (ÁVH) from within the building. When the students were fired on, a student died and was wrapped in a flag and held above the crowd. This was the start of the revolution. As the news spread, disorder and violence erupted throughout the capital.

The revolt spread quickly across Hungary and the government collapsed. Thousands organised into militias, battling the ÁVH and Shugarhai troops. Pro-Hungarian shugarists and ÁVH members were often executed or imprisoned and former political prisoners were released and armed.
