Todor Hristov Zhivkov (Bulgarian: Тодор Христов Живков [ˈtɔdor ˈxristof ˈʒifkof]; 7 September 1911 – 5 August 1998) was a Bulgarian communist statesman who served as the de facto leader of the People's Republic of Bulgaria (PRB) from 1954 until 1989 as General Secretary of the Central Committee of the Bulgarian Communist Party. He was the second longest-serving leader in the Eastern Bloc, the longest-serving leader within the Warsaw Pact and the longest-serving non-royal ruler in Bulgarian history.
During World War II, Zhivkov participated in Bulgaria's resistance movement in the People's Liberation Insurgent Army. In 1943, he was involved in organising the Chavdar Partisan Brigade in and around his place of birth, becoming deputy commander of the Sofia operations area in the summer of 1944. Under his rule, many fellow former combatants with Chavdar were to rise to positions of prominence in Bulgarian affairs. He is said to have coordinated partisan movements with those of pro-Soviet army units during the 9 September 1944 uprising.
