János Kádár
During the Hungarian Uprising, an estimated 20,000 people were killed, nearly all during the Soviet intervention. Imre Nagy was arrested and replaced by the Soviet loyalist János Kádár. Nagy was imprisoned until his execution in 1958. Other government ministers or supporters who were either executed or died in captivity included Pál Maléter, Géza Losonczy, Attila Szigethy and Miklós Gimes.
