The Nuba people are indigenous inhabitants of central Sudan. The Nuba are made up of 50 various indigenous ethnic groups who inhabit the Nuba Mountains of South Kordofan state in Sudan, encompassing multiple distinct people that speak different languages which belong to at least two unrelated language families. Since 2011, when the southern part of Sudan became an independent state as South Sudan, the Nuba now live in the southern part of Sudan. Estimates of the Nuba population vary widely; the Sudanese government estimated that they numbered 2.07 million in 2003.

The Baggāra or Chadian Arabs are a nomadic confederation of people of mixed Arab and Arabized indigenous African ancestry, inhabiting a portion of the Sahel mainly between Lake Chad and the Nile river near south Kordofan, numbering over six million. They are known as Baggara and Abbala in Sudan, and as Shuwa Arabs in Cameroon, Nigeria and Western Chad. The term Shuwa is said to be of Kanuri origin.
