First Secretary of the Hungarian Socialist Workers’ Party (1956–88) and Prime Minister (1956–58) and (1961–65). He replaced Imre Nagy as Premier after crushing the Hungarian uprising of 1956. Kádár consistently supported the Soviet Union, involving Hungarian troops in the 1968 invasion of Czechoslovakia, while retaining a degree of decentralization for the economy. His policy of ‘consumer socialism’ made Hungary the most affluent state in eastern Europe. He was removed as First Secretary following his resistance to the political reforms of the 1980s.
