Kalenjin is an ethnic group of Nilotic origin living in the East African Rift in western Kenya and eastern Uganda. The Kalenjin population is estimated at roughly 4.4 million. There are several smaller tribal groupings within the Kalenjin: Elgeyo, Endorois, Kipsigis, Marakwet, Nandi, Pokot, Sabaot, Terik, Tugen and Sebei. They are pastoralists and are believed to have migrated to their present location from Sudan 2,000 years ago. Until the early 1950s the Kenyan peoples now known as the Kalenjin did not have a common name; they were usually referred to as the 'Nandi-speaking tribes' by scholars and administration officials, a practice that did not immediately come to a halt after the adoption of the common name 'Kalenjin' (cf. Evans-Pritchard 1965). In the late 1940s and the early 1950s, several Nandi-speaking peoples united to assume the common name 'Kalenjin', a Nandi expression meaning I say (to you).
