Kadu
The Kadu are the Nuba groups of the Kadugli district in the Nuba Mountains of South Kordofan, including the Keiga and Krongo peoples; their closely related tongues form the Kadu, or Kadugli–Krongo, language family, once classed within Niger-Congo but later placed in the Nilo-Saharan family. They farm the rainy-season hills and raise cattle around Kadugli.
