Congo, 1978 — dissident coup conspiracy
Event Summary
This entry is coded 14 August 1978, during the unstable interregnum under General Joachim Yhombi-Opango, head of state of the People's Republic of the Congo, the Marxist-Leninist one-party state in Brazzaville. Yhombi-Opango, associated with the right wing of the ruling Congolese Labour Party, had become head of state after the assassination of President Marien Ngouabi in March 1977, and his roughly two-year rule was marked by factional infighting within the party and military, renewed purges of suspected dissidents, and a protracted power vacuum, with northern loyalists maneuvering against perceived rivals. He was accused of attempting to form a rightist faction in the party, and was forced to resign in February 1979 under pressure from the PCT Central Committee, when Denis Sassou Nguesso, the defense minister who had controlled the security apparatus since 1974, formed a military committee to oust him.
The August 1978 coding sits in this period of factional plotting within the party and military as tensions built toward Yhombi-Opango's fall.
