Kipsigis

The Kipsigis are the largest tribe of the Kalenjin ethnic group and speak Kipsigis, a dialect of the Kalenjin language which is classified as a Southern Nilotic. Their dialect is identified by their community eponym Kipsigis. While often cited as representing nearly half of all Kalenjin people, official 2019 data placed their share at approximately (30.1%) with a population at 1,916,317. Joshua Project provides modern population estimates reaching 2.6 million in 2025–2026 and explores the "Pharaoh's army" oral tradition alongside standard Nilotic migration theories.
