After
a Hutu-led coup attempt in October 1965, Mwambutsa IV went into exile in
Switzerland, while Prime Minister
Léopold Biha was hospitalized. Though the monarch attempted to rule from abroad, this effectively left Burundi without a state head. The country was also heavily affected by the coup's aftermath, as Tutsi officers under Michel Micombero purged the security forces and political leadership of Hutu figures. In March 1966, Mwambusta IV designated Charles Ndizeye, his only surviving son, as
heir apparent and entrusted him with overseeing Burundi's government. The Crown Prince then formally
deposed his father and his father's government in July 1966. On 8 July, Ndizeye declared the dismissal of Prime Minister Biha and the suspension of the constitution. The following day he asked Micombero to form a government. On 12 July Micombero presented his government to the prince with himself as Prime Minister and Minister of Defence. Ndizeye was formally crowned as
mwami on 3 September, taking the regnal name Ntare V. The cooperation between Ntare V and Micombero was short-lived. Tensions between the soldiers in the government and the monarchy emerged in August and led to a reshuffling of the cabinet in September. On 7 November Ntare V attempted to broadcast a decree dismissing Micombero's government, but was turned away from the radio station by soldiers. Three weeks later, Ntare V was in the
Democratic Republic of the Congo on a
state visit, celebrating the
takeover of
Mobutu Sese Seko. On 28 November, the king heard over radio that Micombero had led a
military coup d'état, abolishing the monarchy and proclaiming Burundi a
republic with himself as its first
President. Overall, Ntare V had the shortest rule of any Burundian
mwami. Ntare V went into exile in
West Germany and later
Uganda. Meanwhile, Micombero's regime had to contend with various forms of resistance and conducted a series of purges. As time went on, the government's support base became increasingly narrow, and it marginalized not just Hutu but also certain Tutsi sub-groups like the
Banyaruguru. In 1971, a group of Tutsi figures were arrested over an alleged plot to restore the monarchy. ==Execution==
