The Romanian Communist Party (Romanian: Partidul Comunist Român [parˈtidul komuˈnist roˈmɨn]; PCR) was a communist party in Romania. Founded in 1921, the party assumed to the power of Romania in 1947 and became the founding and ruling party of the Socialist Republic of Romania, until its overthrow in the Romanian revolution in 1989. Ideologically committed to Marxism–Leninism, the party oversaw Romania's departure from the Soviet satellite status and incorporation of national communism.
The successor to the pro-Bolshevik wing of the Socialist Party of Romania, it gave an ideological endorsement to a communist revolution that would replace the social system of the Kingdom of Romania. After being outlawed in 1924, the PCR remained a minor and illegal grouping for much of the interwar period and submitted to direct Comintern control. During the 1920s and the 1930s, most of its activists were imprisoned or took refuge in the Soviet Union, which led to the creation of competing factions that sometimes came into open conflict. That did not prevent the party from participating in the political life of the country through various front organizations, most notably the Peasant Workers' Bloc. In 1934–1936, PCR reformed itself in the mainland of Romania properly, with foreign observers predicting a possible communist takeover in Romania. The party emerged as a powerful actor on the Romanian political scene in August 1944, when it became involved in the royal coup that toppled the pro-Nazi government of Ion Antonescu. With support from Soviet occupational forces, the PCR pressured King Michael I into abdicating, and it established the Romanian People's Republic in December 1947.
