Kádár, János

Hungarian communist leader, in power 1956–88, after suppressing the national uprising. As leader of the Hungarian Socialist Workers' Party (HSWP) and prime minister 1956–58 and 1961–65, Kádár introduced a series of market-socialist economic reforms, while retaining cordial political relations with the USSR.

Kádár was a mechanic before joining the outlawed Communist Party and working as an underground resistance organizer in World War II. After the war he was elected to the National Assembly, served as minister for internal affairs 1948–50, and became a prominent member of the Hungarian Workers' Party (HSP). Imprisoned 1951–53 for deviation from Stalinism, Kádár was rehabilitated in 1955, becoming party leader in Budapest, and in November 1956, at the height of the Hungarian national rising, he was appointed head of the new HSWP. With the help of Soviet troops, he suppressed the revolt. He was ousted as party general secretary in May 1988, and forced into retirement in May 1989.
