Todor Zhivkov, Bulgarian commander and politician, 36th Prime Minister of Bulgaria (b. 1911)

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 Bulgarian Communist Party. He was the second longest-serving leader in the Eastern Bloc after Yumjaagiin Tsedenbal, the longest-serving leader within the Warsaw Pact and the longest-serving non-royal ruler in Bulgarian history.He became First Secretary of the Bulgarian Communist Party (BCP) in 1954 (General Secretary from April 1981), served as Prime Minister from 1962 to 1971 and from 1971 onwards as Chairman of the State Council, concurrently with his post as First Secretary. He remained in these positions for 35 years, until 1989, thus becoming the second longest-serving leader of any European Eastern Bloc nation after World War II, and one of the longest ruling non-royal leaders in modern history. His rule marked a period of unprecedented political and economic stability for Bulgaria, marked both by complete submission of Bulgaria to Soviet Union and a desire to expand ties with the West. His rule remained unchallenged until the deterioration of east–west relations in the 1980s, when a stagnating economic situation, a worsening international image and growing careerism and corruption in the BCP weakened his position. He resigned on 10 November 1989, under pressure by senior BCP members due to his refusal to recognise problems and deal with public protests. Within a month of Zhivkov's ouster, Communist rule in Bulgaria had effectively ended, and within a year the People's Republic of Bulgaria had formally ceased to exist.
