Darfur (Arabic: دار فور aar foor, lit. "realm of the Fur") is a region in Sudan. An independent sultanate for several hundred years, it was incorporated into Sudan by Anglo-Egyptian forces. The region is divided into three federal states: West Darfur, South Darfur, and North Darfur which are coordinated by a Transitional Darfur Regional Authority. Due to the Darfur Conflict, the region has been in a state of humanitarian emergency since 2003.
