The People's Republic of the Congo (French: République populaire du Congo) was a Marxist–Leninist socialist state that existed in the Republic of the Congo from 1969 to 1992. The People's Republic of the Congo was founded in December 1969 as the first Marxist-Leninist state in Africa three months after the government of Alphonse Massamba-Débat was overthrown in the September 1968 coup d'état. The ruling Congolese Party of Labour (French: Parti congolais du travail, PCT) appointed Marien Ngouabi as president who established the Congo as a one-party communist government aligned with the Soviet Union. Ngouabi was assassinated in 1977 and succeeded by Joachim Yhombi-Opango until he was overthrown in 1979. Denis Sassou Nguesso succeeded Yhombi-Opango, confirmed the PCT's rule in the Congo with a new constitution, formed closer relations with France, and allowed greater foreign investment in the country.
