Central African Republic (CAF)Central Africa, AfricaJanuary 1, 1966
Event Summary
On the night of December 31, 1965 into January 1, 1966, Colonel Jean-Bedel Bokassa, commander of the Central African Republic's small army, overthrew his cousin President David Dacko in the Saint-Sylvestre coup. By 1965 Dacko's one-party rule was mired in corruption, economic stagnation, and cross border rebel incursions, and Dacko, aware of Bokassa's ambitions, had built up a rival gendarmerie under Jean Izamo. Warned that a summons from Izamo was a trap, Bokassa, aided by Captain Alexandre Banza, struck first on New Year's Eve: they lured Izamo to Camp de Roux and locked him in a cellar, seized Radio-Bangui and the presidential palace, and after midnight arrested Dacko as he returned to the capital, forcing him to resign and imprisoning him at Camp Kassai.
Officially eight people died resisting the coup. Bokassa dissolved the National Assembly, abolished the 1959 constitution, cut ties with China, and made himself president under a Revolutionary Council. Dacko's life was spared only because France threatened to cut aid if he was killed; Izamo and the security chief Mounoumbaye were tortured to death within weeks.
Bokassa ruled for thirteen years, crowning himself emperor in 1976.

Sources
The Saint-Sylvestre coup was staged by Jean-Bedel Bokassa, commander in chief of the CAR army, and his officers against President David Dacko on 31 December 1965 and 1 January 1966; with Captain Alexandre Banza's aid Bokassa captured Izamo and locked him in a cellar, occupied Bangui, and after midnight arrested Dacko, forcing him to resign and imprisoning him at Camp Kassai, with eight people reported killed and Dacko's life spared because of a French request, after which Bokassa dissolved the National Assembly, abolished the constitution, and cut ties with China.
Jean-Bedel Bokassa served as the second president of the Central African Republic after seizing power in the Saint-Sylvestre coup on 1 January 1966, later establishing the Central African Empire with himself as emperor until his 1979 overthrow; he had become the army's first colonel on 1 December 1964 and commander in chief of the roughly 500 soldiers, rising quickly as Dacko's cousin.
On the first day of 1966 citizens of the CAR awakened under a military dictatorship as army head General Bokassa overthrew elected president Dacko; the coup succeeded partly because of close CAR French ties and French influence over the budget, and it came after Dacko began overtures to China and Mao, with the new Bokassa regime proving loyal to the French who propped it up for about thirteen years.

Editorial Note
Coding note: killings occurred (officially eight died resisting, and Izamo and security chief Mounoumbaye were tortured to death within weeks), but the dataset codes the deposed leader Dacko as placed under house arrest, which matches his fate: forced to resign, imprisoned, spared at French insistence, and later held under varying detention and house arrest; the surrounding deaths are recorded per the killings protocol with sources cited, without editorializing. Date structure: the coup began the night of December 31, 1965 (Saint-Sylvestre) and Dacko was arrested in the first hours of January 1, 1966, the dataset's date. Arc note: Bokassa crowned himself emperor in 1976 and was overthrown in 1979, with Dacko returned to the presidency in that French-backed operation.
