Britain's possessions in British East Africa during the colonial period. The colonial history of Kenya dates from the establishment of a German protectorate over the Sultan of Zanzibar's coastal possessions in 1885, followed by the arrival of the Imperial British East Africa Company in 1888. Incipient imperial rivalry was forestalled when Germany handed its coastal holdings to Britain in 1890. This was followed by the building of the Kenya–Uganda railway passing through the country. This was resisted by some tribes — notably the Nandi led by Orkoiyot Koitalel Arap Samoei for ten years from 1890 to 1900 — still the British eventually built the railway. The Nandi were the first tribe to be put in a native reserve to stop them from disrupting the building of the railway. During the railway construction era, there was a significant inflow of Indian peoples, who provided the bulk of the skilled manpower required for construction.
