The Tutsi (/ˈtʊtsi/ TUUT-see), also called Watusi, Watutsi or Abatutsi (Kinyarwanda pronunciation: [ɑ.βɑ.tuː.t͡si]), are an ethnic group established primarily in Rwanda and Burundi. They are a Bantu-speaking people and the second-largest of three main ethnic groups in Rwanda and Burundi, the other two being the Hutu and Twa.
Historically, the Tutsi were pastoralists and filled the ranks of the warrior caste. Before 1962, they regulated and controlled Rwandan society, which consisted of Tutsi aristocrats and Hutu commoners under a clientship structure. The Tutsi occupied the dominant positions in the sharply stratified society and constituted the ruling class.
