The Kawahla fought with the Juhayna Arabs to bring a end to the Christian Nubian kingdom Makuria, through a combination of conquest and intermarriage in the mid 14th century the kingdom of Makuria fell, resulting in an Arab Islamic dynasty (Banu Kanz) in Nubia. Most of the Kawahla are farmers, the main crops they grow are sorghum, wheat, cotton, beans (luba) and fruits such as La loba and Nabag. Studies of the Kawahla in Kurdufan found that they migrate away from the wet season pasture to grazing land near permanent wells to wait for the dry season.[4] In the 19th century, Hedley Vicars encountered the Kawahla, whom asked him to settle their dispute with other tribes.[5]Lord Edward Gleichen also wrote about the Kawahla.[6][7]
