Władysław Gomułka (Polish: [vwaˈdɨswaf ɡɔˈmuwka]; 6 February 1905 – 1 September 1982) was a Polish communist politician. He was the de facto leader of post-war Poland from 1947 until 1948. Following the Polish October he became leader again from 1956 to 1970. Gomułka was initially very popular for his reforms; his seeking a "Polish way to socialism"; and giving rise to the period known as "Gomułka's thaw". During the 1960s, however, he became more rigid and authoritarian—afraid of destabilizing the system, he was not inclined to introduce or permit changes. In the 1960s he supported the persecution of the Catholic Church, intellectuals and the anti-communist opposition.
