Civil war and genocides

In late April 1972, two events led to the outbreak of the First Burundian Genocide. On 27 April 1972, a rebellion led by Hutu members of the gendarmerie broke out in the lakeside towns of Rumonge and Nyanza-Lac and the rebels declared the short-lived Martyazo Republic. The rebels attacked both Tutsi and any Hutu who refused to join their rebellion. During this initial Hutu outbreak, anywhere from 800 to 1200 people were killed. At the same time, King Ntare V of Burundi returned from exile, heightening political tension in the country. On 29 April 1972, the 24-year-old Ntare V was murdered. In subsequent months, the Tutsi-dominated government of Michel Micombero used the army to combat Hutu rebels and commit genocide, murdering targeted members of the Hutu majority. The total number of casualties was never established, but contemporary estimates put the number of people killed between 80,000 and 210,000. In addition, several hundred thousand Hutu were estimated to have fled the killings into Zaïre, Rwanda and Tanzania.

Following the civil war and genocide, Micombero became mentally distraught and withdrawn. In 1976, Colonel Jean-Baptiste Bagaza, a Tutsi, led a bloodless coup to topple Micombero and set about promoting reform. His administration drafted a new constitution in 1981, which maintained Burundi's status as a one-party state. In August 1984, Bagaza was elected head of state. During his tenure, Bagaza suppressed political opponents and religious freedoms.

Major Pierre Buyoya, a Tutsi, overthrew Bagaza in 1987, suspended the constitution and dissolved political parties. He reinstated military rule by a Military Committee for National Salvation (CSMN). Anti-Tutsi ethnic propaganda disseminated by the remnants of the 1972 UBU, which had re-organized as PALIPEHUTU in 1981, led to killings of Tutsi peasants in the northern communes of Ntega and Marangara in August 1988. The government put the death toll at 5,000, some international NGOs believed this understated the deaths.

The new regime did not unleash the harsh reprisals of 1972. Its effort to gain public trust was eroded when it decreed an amnesty for those who had called for, carried out, and taken credit for the killings. Analysts have called this period the beginning of the "culture of impunity." Other analysts put the origins of the "culture of impunity" earlier, in 1965 and 1972, when a small number of identifiable Hutus unleashed massive killings of Tutsis.

In the aftermath of the killings, a group of Hutu intellectuals wrote an open letter to Pierre Buyoya, asking for more representation of the Hutu in the administration. They were arrested and jailed. A few weeks later, Buyoya appointed a new government, with an equal number of Hutu and Tutsi ministers. He appointed Adrien Sibomana (Hutu) as Prime Minister. Buyoya also created a commission to address issues of national unity. In 1992, the government created a new constitution that provided for a multi-party system, but a civil war broke out.

An estimated total of 250,000 people died in Burundi from the various conflicts between 1962 and 1993.

Since Burundi's independence in 1962, two genocides have taken place in the country: the 1972 mass killings of Hutus by the Tutsi-dominated army, and the mass killings of Tutsis in 1993 by the Hutu majority. Both were described as genocides in the final report of the International Commission of Inquiry for Burundi presented in 2002 to the United Nations Security Council.
