The Tutsis are an ethnic group from the African Great Lakes region, particularly in Rwanda and Burundi, historically known for their cattle herding and taller physical stature compared to the Hutus. The Tutsis became central figures in the Rwandan Genocide of 1994, a mass atrocity that highlighted the violent ethnic tensions between them and the Hutu majority, resulting in the systematic murder of an estimated 800,000 Tutsis and moderate Hutus over approximately 100 days.
