Mass killings of Tutsis were conducted by the majority-Hutu populace in Burundi from 21 October to December 1993, under an eruption of ethnic animosity and riots following the assassination of Burundian President Melchior Ndadaye in an attempted coup d'état. The massacres took place in all provinces apart from Makamba and Bururi, and were primarily undertaken by Hutu peasants. At many points throughout, Tutsis took vengeance and initiated massacres in response. The United Nations Population Fund and the Government of Burundi conducted study in 2002 which concluded that a total of 116,059 people died during the events. The question of whether the killings of Tutsis arose from a planned genocide or from spontaneous violence remains heavily disputed among academics and Burundians who lived through the events. Background From the mid-1960s, the country of Burundi was politically dominated by its Tutsi ethnic minority at the expense of the Hutu majority. Union pour le Progrès National (UPRONA), which served as the legal ruling party from 1966, was overwhelmingly made up of Tutsis. Military officers dominated the presidency, coming to power through coups. During this time there were instances of ethnic repression, particularly in 1972 when the Burundian Army quashed a Hutu rebellion and then murdered thousands of civilians. In 1987 Pierre Buyoya became President of Burundi following a coup. He initially ignored the country's ethnic strife and perpetuated Tutsi domination of public life. In August 1988 violence broke out and the army massacred thousands of Hutus. Facing substantial foreign pressure, Buyoya initiated reforms designed to end Burundi's systemic ethnic violence, while UPRONA attempted to incorporate more Hutus into its ranks. The Tutsi establishment in the army and security forces nevertheless resisted change. A commission appointed by the president produced a constitution which provided for democratic elections. The document was adopted via referendum in March 1992 followed shortly thereafter by the creation of new political parties. Buyoya scheduled free elections in 1993 and offered himself as UPRONA's presidential candidate. UPRONA's main challenger became Front pour la Démocratie au Burundi (FRODEBU), a party largely associated with Hutus. In the 1 June presidential election Buyoya faced Melchior Ndadaye, who was backed by FRODEBU. Ndadaye won the election in a landslide, earning 64 percent of the popular vote. In the subsequent parliamentary elections on 29 June, FRODEBU won 71.4 percent of the vote and earned 80 percent of the seats in the National Assembly. The party also
