The Pokot people (also spelled Pökoot) live in West Pokot County and Baringo County in Kenya and in the Pokot District of the eastern Karamoja region in Uganda. They form a section of the Kalenjin ethnic group and speak the Pökoot language, which is broadly similar to the related Marakwet, Nandi, Tuken and other members of the Kalenjin language group.
Halfway through the nineteenth century, the Pokot expanded their territory rapidly into the lowlands of the Kenyan Rift Valley, mainly at the expense of the Laikipia Maasai people. This was the formation of the plains Pokot, and is captured in their historical narratives.
In that account, when the Pokot nation was forming on the Elgeyo escarpment, the Kerio Valley was occupied by the Samburu. Whenever the Pokot descended into the valley, they were harassed and raided by the Samburu, "Until there arose a wizard among the [Pokot] who prepared a charm in the form of a stick, which he placed in the Samburu cattle kraals, with the result that all their cattle died". The Samburu are said to have then left the Kerio Valley and moved to En-ginyang where they formed a large settlement.
Once the Pokot saw that the Kerio Valley was no longer occupied, they descended in large numbers and occupied Tiati and the hills as far south as Ka-ruwon.
Many Pokot people from the present eastern part of the Pokot area claim that they come from the hilly areas of northern Cherengani.
The Turkana and Pokot ethnic groups have organized cattle raids against each other. The two groups have been through numerous periods of war and peace.
Kenya's 2009 census puts the total number of Pokot speakers at about 620,000 in Kenya (roughly 133,000 Pokot in Baringo county and close to 500,000 in West Pokot county). In addition, there are close to 100,000 Pokot speakers in Uganda. A fair estimate thus places the number of Pokot speakers in Kenya and Uganda at 700,000.
