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.

Rwanda, officially the Republic of Rwanda, is a landlocked country in the Great Rift Valley of Central Africa, where the African Great Lakes region and Southeast Africa converge. Located a few degrees south of the Equator, Rwanda is bordered by Uganda, Tanzania, Burundi, and the Democratic Republic of the Congo. It is highly elevated, giving it the soubriquet "land of a thousand hills", with its geography dominated by mountains in the west and savanna to the southeast, with numerous lakes throughout the country. The climate is temperate to subtropical, with two rainy seasons and two dry seasons each year. It is the most densely populated mainland African country; among countries larger than 10,000 km2, it is the fifth most densely populated country in the world. Its capital and largest city is Kigali.
