Koitalel Arap Samoei
Koitalel Arap Samoei followed his father Kimnyole as the Orkoiyot  and was enthroned in 1885. When British colonials began building the Uganda Railway through the Nandi area, he led an eleven-year resistance movement against the railway. On October 19, 1905, he was invited by British Col. Richard Meinertzhagen under the guise of negotiating a truce, and was instead murdered along with his companions.
His son, Barsirian Arap Manyei (born 1882), was the Nandi leader from 1919 until 1922 when he was detained by the British. Barsirian was not released until 1964, making him the longest-serving political prisoner in Kenyan history.
