Mátyás Rákosi

Mátyás Rákosi (; born Mátyás Rosenfeld; 9 March 1892 – 5 February 1971) was a Hungarian communist politician who was the "de facto" leader of Hungary from 1947 to 1956. 
During his rule in Hungary, there was a political transition from the regime of people's democracy to a socialist state, as well as the accelerated Sovietization of Hungary, accompanied by political repression. Three years after Stalin's death, some time after the 20th Congress of the Communist Party of the Soviet Union, which adopted the historic resolution "On the cult of personality and its consequences", he was dismissed.
