The War in Darfur, also nicknamed the Land Cruiser War, was a major armed conflict in the Darfur region of Sudan that began in February 2003 when the Sudan Liberation Movement (SLM) and the Justice and Equality Movement (JEM) rebel groups began fighting against the government of Sudan, which they accused of oppressing Darfur's non-Arab population. The government responded to attacks by carrying out a campaign of ethnic cleansing against Darfur's non-Arabs. This resulted in the death of hundreds of thousands of civilians and the indictment of Sudan's president, Omar al-Bashir, for genocide, war crimes, and crimes against humanity by the International Criminal Court.

Darfur is a region of western Sudan. Dār is an Arabic word meaning "home [of]" – the region was named Dardaju while ruled by the Daju, who migrated from Meroë c. 350 AD, and it was renamed Dartunjur when the Tunjur ruled the area. Darfur was an independent sultanate for several hundred years until 1874, when it fell to the Sudanese warlord Rabih az-Zubayr. The region was later invaded and incorporated into Sudan by Anglo-Egyptian forces in 1916. As an administrative region, Darfur is divided into five federal states: Central Darfur, East Darfur, North Darfur, South Darfur and West Darfur. Because of the War in Darfur between Sudanese government forces and the indigenous population, the region has been in a state of humanitarian emergency and genocide since 2003. The factors include religious and ethnic rivalry, and the rivalry between farmers and herders.
