Dār Fertit is a historical term for the lowlands south of Darfur and east of the highlands in the east of the modern-day Central African Republic that contain tributaries of the White Nile River. This region included parts of southwestern Sudan and northwestern South Sudan. In the present era, Fertit is a catch-all word for non-Dinka, non-Arab, non-Luo, non-Fur groups and tribes in Western Bahr el Ghazal, South Sudan. Even though these groups often speak different languages and have a history of inter-tribal violence, they have become more unified over time, mostly out of opposition to the Dinka people.
