Mihály András Vajda is a Hungarian leftist intellectual who took part in the debates surrounding the development of national socialism, Marxism–Leninism, and the state of capitalism in the latter half of the 20th century. Involved in politics in his home country of Hungary, Vajda was expelled along with several other scholars from the Hungarian Socialist Workers Party in 1973 due to allegedly representing views that were "opposed to Marxism–Leninism and to the policy of the Hungarian Socialist Workers' Party."
