Southern Nilotes settle the western highlands
The Kalenjin peoples are Southern Nilotes, the branch that has lived longest in the Kenyan highlands, with roots in the region reaching back well over a thousand years. Early Southern Nilotic herders spread across the Rift Valley escarpments, Mount Elgon slopes, and Mau highlands. From this deep base grew the later Nandi, Kipsigis, Tugen, Marakwet, Keiyo, and Sabaot.
