The Rwandan Patriotic Front and civil war

The Rwandan Patriotic Front (RPF), an organization of Tutsi exiles based in Uganda, invaded Rwanda in October 1990. The civil war that followed strengthened Hutu extremism. Government propaganda increasingly described Tutsis as inyenzi (cockroaches) who needed to be exterminated. A peace agreement (the Arusha Accords) was reached in 1993 with provisions for power sharing, but Hutu extremists had no intention of honoring it. They began preparing for genocide.
