On July 8, 1966 forces loyal to Crown Prince Charles Ndizeye overthrew the pro-monarchy government of Burundi and deposed the absent king, Mwami Mwambutsa IV, the second of three coups that convulsed Burundi in 1965 and 1966. Mwambutsa had fled the country in October 1965 after a failed Hutu led coup attempt, and on March 24, 1966 had delegated his royal powers to his 18-year-old son Ndizeye while remaining in exile. On July 8, 1966 forces loyal to Ndizeye overthrew the pro-Mwambutsa government of Prime Minister Leopold Biha; Ndizeye announced he was assuming the role of head of state, suspended the constitution, dismissed Biha, and asked the 26-year-old Tutsi army captain Michel Micombero, who had played a major role in the coup, to form a government, installed on July 12.
On September 1 Ndizeye had himself crowned Mwami Ntare V. The coup was an extreme Tutsi counter-reaction against Mwambutsa's attempts to balance Hutu and Tutsi demands. Tension soon grew between the young king and Micombero, whose own coup in November 1966 would abolish the monarchy entirely.

The July 1966 coup was the second in Burundi's post-independence history, ousting the government loyal to the king Mwambutsa IV, who had gone into exile in October 1965 after the failure of an earlier coup attempt; the July 1966 coup was an extreme Tutsi counter-reaction against what they saw as Mwambutsa's dangerous moderate tendencies in trying to balance Hutu and Tutsi demands in government.

On 1 September 1966 Ndizeye had himself crowned as Mwami Ntare V, but tension developed between Ntare, who wanted to actively rule as a monarch, and Micombero's government; less than five months after July, Micombero led a third coup on 28 November which ousted Ntare, abolished the monarchy, and declared Burundi a republic with Micombero as its first president.
SOURCE REVIEWEDWikipedia, November 1966 Burundian coup d'etatopen source ↗
A record of Burundi's coups lists the sequence as the failed coup against Mwambutsa IV of 18 to 19 October 1965, Ntare V overthrowing Mwambutsa IV on 8 July 1966, and Michel Micombero overthrowing Ntare V on 28 November 1966, confirming the July event as the son deposing the absent father.

Editorial Note
Verification of the paired trap: the dataset's Burundi 1966-07-08 is the palace coup in which Crown Prince Charles Ndizeye deposed his absent father Mwami Mwambutsa IV and took the throne as Ntare V; the separate November 28, 1966 Micombero coup (abolishing the monarchy and deposing Ntare V) is a distinct event likely to appear as its own dataset record in a later batch, and must not be conflated with this one. Fate coding: Mwambutsa was already in exile abroad and deposed in absentia, so the not physically harmed fate holds. Context noted: Ntare V returned from exile in 1972 and was assassinated, but that is outside this event.
Cross-Reference
Datasets agree. At least two of the three reference datasets we check against carry this event, and none of them disagrees about its date or its result.
