Georgi Dimitrov (1882-1949) was a Bulgarian communist politician who served as the first leader of communist Bulgaria from 1946 to 1949. A prominent figure in the international communist movement, he gained international recognition for his defiance of the Nazi regime during the Reichstag Fire trial in 1933. Following his acquittal, he became Secretary-General of the Comintern (Communist International). After World War II, he returned to Bulgaria, paving the way for the establishment of a communist state aligned with the Soviet Union. Dimitrov's leadership was marked by collectivization, nationalization, and a focus on industrialization, and he remains a controversial figure in Bulgarian history.
