In a military coup, Michel Micombero abolished the Burundian monarchy and declared the country a republic with himself as president.

Michel Micombero was a Burundian military officer and politician who ruled the country as de facto military dictator for the decade between 1966 and 1976. He was the last Prime Minister of the Kingdom of Burundi from July to November 1966, and the first President of the country from November 1966 until his overthrow in 1976.

The Kingdom of Burundi, also known as Kingdom of Urundi, was a Bantu kingdom in the modern-day Republic of Burundi. The Ganwa monarchs ruled over both Hutus and Tutsis. Created in the 16th century, the kingdom was preserved under German and Belgian colonial rule in the late 19th and early 20th century and was an independent state between 1962 and 1966.

The president of Burundi, officially the President of the Republic, is the head of state and head of government of the Republic of Burundi. The president is also commander-in-chief of the National Defence Force. The office of the presidency was established when Michel Micombero declared Burundi a republic on 28 November 1966. The first constitution to specify the powers and duties of the president was the constitution of 1974 adopted in 1976. The constitution, written by Micombero, affirmed Micombero's position as the first president of Burundi. The powers of the president currently derive from the 2005 constitution implemented as a result of the 2000 Arusha Accords after the Burundian Civil War. The current president since 18 June 2020 is Évariste Ndayishimiye.
