The 1984 Guinean coup d'état was the bloodless military coup that took place in Guinea on 3 April 1984, led by Colonel Lansana Conté. It led to the deposition of Prime Minister Louis Lansana Beavogui, who held the office since 1972, and assumed interim presidential powers on 26 March, when the long-time President Ahmed Sékou Touré died during an emergency heart operation at the Cleveland Clinic in the United States.
Colonel Conté announced the dissolution of the ruling Democratic Party of Guinea (PDG), the National Assembly and all mass organizations, suspension of the Constitution, creation of the Military Committee of National Restoration (CMNR) as the ruling junta, and ordered release of political prisoners held at Camp Boiro concentration camp. Conté was named new President on 5 April.
Eventually, a power struggle developed between Conté and a fellow member of the CMNR, Diarra Traoré (who briefly served as Prime Minister in April–December 1984), with the latter being executed in the aftermath of a failed coup attempt in July 1985. Conté took advantage of the coup attempt to execute several of Ahmed Sekou Touré's close associates, including his half-brother Ismaël Touré (former chief prosecutor at Camp Boiro), Mamadi Keïta, Siaka Touré (former commander of Camp Boiro), Moussa Diakité, and Abdoulaye Touré (former Minister of Foreign Affairs).
