Subsequently, Nagy was granted asylum in the United States. He would be Hungary's last non-Communist head of government until the collapse of Communist rule and restoration of free elections in 1989–90. In addition, he would be the last prime minister east of the Iron Curtain not to be a Communist or Communist sympathizer until Tadeusz Mazowiecki of Poland in 1989 (while Czechoslovakia maintained a multi-party system until the coup d'état of February 1948, its prime minister at the time of Nagy's ouster was the Communist leader Klement Gottwald).
