The United Nations Assistance Mission for Rwanda (UNAMIR) was established by United Nations Security Council Resolution 872 on 5 October 1993. It was intended to assist in the implementation of the Arusha Accords, signed on 4 August 1993, which was meant to end the Rwandan Civil War. The mission lasted from October 1993 to March 1996. Its activities were meant to aid the peace process between the Hutu-dominated Rwandese government and the Tutsi-dominated rebel Rwandan Patriotic Front (RPF). The UNAMIR has received much attention for its role in failing, due to the limitations of its rules of engagement, to prevent the Rwandan genocide and outbreak of fighting. Its mandate extended past the RPF overthrow of the government and into the Great Lakes refugee crisis. The mission is thus regarded as a major failure.

The Rwandan Civil War was a large-scale civil war in Rwanda which was fought between the Rwandan Armed Forces, representing the country's government, and the rebel Rwandan Patriotic Front (RPF) from 1 October 1990 to 18 July 1994. The war arose from the long-running dispute between the Hutu and Tutsi groups within the Rwandan population. A 1959–1962 revolution had replaced the Tutsi monarchy with a Hutu-led republic, forcing more than 336,000 Tutsi to seek refuge in neighbouring countries. A group of these refugees in Uganda founded the RPF which, under the leadership of Fred Rwigyema and Paul Kagame, became a battle-ready army by the late 1980s.
