The Rwandan genocide, also known as the genocide against the Tutsi, was a genocidal mass slaughter of Tutsi in Rwanda by members of the Hutu majority government. An estimated 500,000 to 1,000,000 Rwandans were killed during the 100-day period from 7 April to mid-July 1994, constituting as many as 70% of the Tutsi population. Additionally, 30% of the Pygmy Batwa were killed. The genocide and widespread slaughter of Rwandans ended when the Tutsi-backed and heavily armed Rwandan Patriotic Front (RPF) led by Paul Kagame took control of the country. An estimated 2,000,000 Rwandans, mostly Hutus, were displaced and became refugees.
