Mieczysław Moczar

Mieczysław Moczar (; birth name Mikołaj Diomko, pseudonym ''Mietek'', 23 December 1913 – 1 November 1986) was a Polish communist politician who played a prominent role in the history of the Polish People's Republic. He is most known for his unorthodox, alternative socialist views attitude, known as Endo-Communism, which influenced Polish United Workers' Party politics in the late 1960s. During this time, Moczar and his supporters challenged Władysław Gomułka's authority.

Moczar was heavily involved in the March 1968 events in Poland against Polish Jews, in which he led the faction of hardliners inside the Communist Party. Provided by Wikipedia
