History
The Rift Valley holds some of humanity's deepest roots. Fossils from around Lake Turkana, including the near-complete skeleton of the Turkana Boy found on the western shore in 1984, and the stone hand-axes of Olorgesailie in Kajiado, record early humans over hundreds of thousands of years and more. In later centuries Nilotic herders — the Maasai in the south, the Kalenjin peoples in the western highlands, the Turkana, Pokot and Samburu in the north — spread across the valley and its grasslands.
The Uganda Railway crossed the valley in 1899–1901, and the Nandi fought it for years until their leader Koitalel Arap Samoei was killed in 1905. The Maasai were moved by treaties in 1904 and 1911 from the central Rift and Laikipia into a southern reserve, opening the land to settlers who laid out wheat, cattle and tea estates around Nakuru, Eldoret, Kericho and Nanyuki. In 1952–53 Jomo Kenyatta and five others were tried at Kapenguria in West Pokot, a trial remembered as a turning point in the independence struggle.
After independence the Rift became a heartland of Kalenjin politics under Daniel arap Moi and, later, William Ruto. Land disputes between long-settled and newer farming communities made it a centre of the 2007–08 post-election violence, including the burning of a church at Kiambaa near Eldoret and reprisal killings in Naivasha and Nakuru. In the north, the Ilemi Triangle is claimed by both Kenya and South Sudan and controlled in practice by Kenya, and oil was found in Turkana in 2012.
