The Kalenjins are estimated to have a population of about 2.7 million people according to 1993 census. They are an ethnic grouping of eight culturally and linguistically related groups or “tribes”. These include; the Kipsigis, Nandi, Tugen, Keiyo, Marakwet, Pokot (sometimes called the Suk), Sabaot (who live in the Mount Elgon region, overlapping the Kenya/Uganda border), and the Terik. Their present-day homeland is Kenya’s western highlands and the Rift Valley.
Together, the Kalenjin comprise Kenya’s fourth-largest ethnic group. The Kipsigis are the largest Kalenjin population, with approximately 470,000 people.
The word “kalenjin” means I say to you in Nandi. Although not all kalenjins are Nandi the name kalenjin has also been used to refer even to the non nandi dialects such as the Kipsigis, Marakwet, Pokot and Tugen.
They migrated to this area 2000 years ago from southern Sudan. The majority of kalenjin groups have taken up agriculture from pastoralist which formed their original behavior. Some, however such as the Okiek have remained in the forests doing hunting and gathering. Beekeeping was also a common activity and the honey was used not only in trade but also for brewing beer.

Administration of the law is carried out at an informal gathering of the clan’s elders and other interested parties in the dispute called kok.
