Zoltán Tildy (18 November 1889 – 4 August 1961), was an influential leader of Hungary, who served as Prime Minister from 1945–1946 and President from 1946 until 1948 in the post-war period before the seizure of power by Soviet-backed communists.
Tildy served as the first President of the Republic of Hungary until July 31, 1948, when he was forced to resign after allegations emerged about his son-in-law being arrested for corruption and adultery. Tildy was held under house arrest in Budapest until 1 May 1956. He was appointed to the position of a state minister in the coalition government during the 1956 Hungarian Revolution. He was eventually arrested by Soviet forces after the revolution was crushed by Warsaw Pact intervention. On June 15, 1958, Tildy was sentenced by the Supreme Court to six years' imprisonment, in the trial of Imre Nagy and associates. However, he was released under an individual amnesty in April 1959 in view of his advanced years (in fact due to illness). He then lived in complete retirement until he died in Budapest on August 4, 1961.
