The Rwandan genocide, also known as the genocide against the Tutsi or the Tutsi genocide, occurred from 7 April to 19 July 1994 during the Rwandan Civil War. Over a span of around 100 days, members of the Tutsi ethnic group, as well as some moderate Hutu and Twa, were systematically killed by Hutu militias. While the Rwandan Constitution states that over 1 million people were killed, most scholarly estimates suggest between 500,000 and 662,000 Tutsi died, mostly men. The genocide was marked by extreme violence, with victims often murdered by neighbours, and widespread sexual violence, with between 250,000 and 500,000 women raped.
The genocide was rooted in long-standing ethnic tensions, most recently from the Rwandan Hutu Revolution from 1959 to 1962, which resulted in Rwandan Tutsi fleeing to Uganda due to the ethnic violence that had occurred. Hostilities were then exacerbated further due to the Rwandan Civil War, which began in 1990 when the Rwandan Patriotic Front (RPF), a predominantly Tutsi rebel group, invaded Rwanda from Uganda. The war reached a tentative peace with the Arusha Accords in 1993. However, the assassination of President Juvénal Habyarimana on 6 April 1994 ignited the genocide, as Hutu extremists used the power vacuum to target Tutsi and moderate Hutu leaders.
