The 2008 Guinean coup d'état was a Guinean military coup d'état that occurred in Guinea on 23 December 2008, shortly after the death of long-time President Lansana Conté. A junta called the National Council for Democracy and Development (Conseil National de la Démocratie et du Development, CNDD), headed by Captain Moussa Dadis Camara, seized power and announced that it planned to rule the country for two years prior to a new presidential election. Camara did indeed step down after Alpha Condé was elected in the 2010 election.
In the early hours of 23 December 2008, Aboubacar Somparé, the President of the National Assembly, announced on television that Conté had died at 6:45 pm local time the previous day "after a long illness." While Somparé did not name the particular illness, sources reported that Conté had chronic diabetes and leukemia. According to the Constitution, the President of the National Assembly is to assume the Presidency in the event of a vacancy, and a new presidential election is to be held within 60 days. Somparé requested that the President of the Supreme Court, Lamine Sidimé, declare a vacancy in the Presidency and apply the Constitution.Prime Minister Ahmed Tidiane Souaré and General Diarra Camara, the head of the army, stood alongside Somparé during his announcement. Declaring 40 days of national mourning for Conté, Souaré urged "calm and restraint". He told the army to secure the borders and maintain calm within the country "in homage to the memory of the illustrious late leader".
