János Kádár
After the Revolution of 1956, Gheorghiu-Dej worked closely with Hungary's new leader, János Kádár, who was installed by the Soviet Union. Romania took Hungary's former premier (leader of the 1956 revolution) Imre Nagy into custody. He was jailed at Snagov, north of Bucharest. After a series of interrogations by Soviets and Romanian authorities, Nagy was returned to Budapest for trial and execution.
