On the night of 31 December 1965 – 1 January 1966, General Bokassa carried out a successful coup d'état against Dacko and prevented the possible assumption of power by a rival, Colonel Jean Izamo, head of the national gendarme police force. Dacko, who belonged to the same Ngbaka ethnic group as Bokassa, was imprisoned, placed under house arrest in Lobaye, but then was released on 16 July 1969 and eventually named personal counselor of President Bokassa on 17 September 1976. When Bokassa's rule came under increasing criticism during the late 1970s, Dacko managed to leave for Paris where the French convinced him to cooperate in a "coup" to remove Bokassa from power and restore him to the presidency.
