The Ikiza (variously translated from Kirundi as the Catastrophe, the Great Calamity, and the Scourge), or the Ubwicanyi (Killings), was a series of mass killings—often characterised as a genocide—which were committed in Burundi in 1972 by the Tutsi-dominated army and government, primarily against educated and elite Hutus who lived in the country. Conservative estimates place the death toll of the event between 100,000 and 150,000 killed, while some estimates of the death toll go as high as 300,000.
History of Burundi
In the 20th century Burundi had three main indigenous ethnic groups: Hutu, Tutsi, and Twa. The area was colonised by the German Empire in the late 1800s and administered as a portion of German East Africa. In Burundi and neighboring Rwanda to the north, the Germans maintained indirect rule, leaving local social structures intact. Under this system, the Tutsi minority generally enjoyed its historically high status as aristocrats, whereas the Hutus occupied the bottom of the social structure. Princely and monarchal rulers belonged to a unique ethnic group, Ganwa, though over time the political salience of this distinction declined and the category was subsumed by the Tutsi grouping. During World War I, Belgian troops from the Belgian Congo occupied Burundi and Rwanda. In 1919, under the auspices of the nascent League of Nations, Belgium was given the responsibility of administering "Ruanda-Urundi" as a mandated territory. Though obligated to promote social progress in the territory, the Belgians did not alter the local power structures. Following World War II, the United Nations was formed and Ruanda-Urundi became a trust territory under Belgian administration, which required the Belgians to politically educate the locals and prepare them for independence.
The inhabitants of Urundi were allowed to participate in politics beginning in 1959. Limited self-government was established in 1961. The Union pour le Progrès national (UPRONA) won in a landslide in national elections and its leader, Louis Rwagasore, became Prime Minister.
