The Bulgarian Communist Party (BCP; Bulgarian: Българска комунистическа партия (БΚП), Romanised: Bŭlgarska komunisticheska partiya (BKP)) was the founding and ruling party of the People's Republic of Bulgaria from 1946 until 1989, when the country ceased to be a socialist state. The party had dominated the Fatherland Front, a coalition that took power in 1944, late in World War II, after it led a coup against Bulgaria's tsarist regime in conjunction with the Red Army's crossing the border. It controlled its armed forces, the Bulgarian People's Army. The BCP was organized on the basis of democratic centralism, a principle introduced by the Russian Marxist scholar and leader Vladimir Lenin, which entails democratic and open discussion on policy on the condition of unity in upholding the agreed upon policies. The highest body of the BCP was the Party Congress, convened every fifth year. When the Party Congress was not in session, the Central Committee was the highest body, but since the body normally met only once a year, most duties and responsibilities were vested in the Politburo and its Standing Committee. The party's leader held the offices of General Secretary. The BCP was committed to Marxism-Leninism, an ideology consisted of the writings of the German philosopher Karl Marx and of Lenin (from 1922 to 1956 as formulated by Soviet leader Joseph Stalin). In the 1960s, the BCP announced some economic reforms, which allowed the free sale of production that exceeded planned amounts. After Soviet Premier Mikhail Gorbachev took power in 1985, the BCP underwent political and economic liberalization, which promptly liquidated the party and dissolved the People's Republic of Bulgaria completely. After the end of the BCP, the party was renamed to the Bulgarian Socialist Party in 1990. History Origins The party's origins lay in the Bulgarian Social Democratic Workers' Party (Narrow Socialists) (Tesni Sotsialisti, "Narrow Socialists"), which was founded in 1903 after a split in the 10th Congress of the Bulgarian Social Democratic Workers' Party. The party's founding leader was Dimitar Blagoev, who was the driving force behind the formation of the BSDWP in 1894. It comprised most of the hardline Marxists in the Social Democratic Workers' Party. The party opposed World War I and was sympathetic to the October Revolution in Russia. Under Blagoev's leadership, the party applied to join the Communist International upon its founding in 1919. Upon joining the Comintern the party was reorganised as the Communist Party
