The two major ethnic groups in Rwanda (Hutu and Tutsi) had a history of competition and conflicting territorial claims. A civil war with the Hutu-dominated government was fought from 1990 to 1993 by a Tutsi rebel force (RPF) based in Uganda, and continued despite a cease-fire agreement.

After a similar civil war broke out in neighboring Burundi, the Hutu presidents of both Burundi and Rwanda were assassinated in April, 1994. This triggered a Hutu-led massacre of hundreds of thousands of Rwandans, both Tutsi and moderate Hutus. This was only ended after the takeover of Rwanda by the Tutsi (RPF) military government.
