In 1888 the Imperial British East Africa Company established claims to territory in what is now Kenya. In 1890 and 1894 British protectorates were established over the sultanate of Zanzibar and the kingdom of Buganda (Uganda), respectively, and in 1895 the company’s territory in Kenya was transferred to the crown as the East Africa Protectorate.

East Africa Protectorate (also known as British East Africa) was an area in the African Great Lakes occupying roughly the same terrain as present-day Kenya (approximately 639,209 km2 (246,800 sq mi)) from the Indian Ocean inland to Uganda and the Great Rift Valley. Although part of the dominions of the Sultan of Zanzibar, it was controlled by Britain in the late 19th century; it grew out of British commercial interests in the area in the 1880s and remained a protectorate until 1920 when it became the colony of Kenya, save for an independent country 16-kilometre-wide (10 mi) coastal strip that became the Kenya protectorate.  

The Colony of Kenya was established on 11 June 1920 when the territories of the former East Africa Protectorate (except those parts of that Protectorate over which His Majesty the Sultan of Zanzibar had sovereignty) were annexed by Britain. The Kenya Protectorate was established on 13 August 1920 when the territories of the former East Africa Protectorate which were not annexed by Britain were established as a British Protectorate. The Protectorate of Kenya was governed as part of the Colony of Kenya by virtue of an agreement between the United Kingdom and the Sultan dated 14 December 1895. The "Colony of Kenya" referred to the interior lands.  

The Colony and the Protectorate each came to an end on 12 December 1963. The United Kingdom ceded sovereignty over the Colony of Kenya and, under an agreement dated 8 October 1963, the Sultan agreed that simultaneous with independence for Kenya, the Sultan would cease to have sovereignty over the Protectorate of Kenya. In this way, Kenya became an independent country under the Kenya Independence Act 1963 which established the "Dominion of Kenya", with Queen Elizabeth II as head of state. Mzee Jomo Kenyatta was the first prime minister. Exactly 12 months later on 12 December 1964, Kenya became a republic under the name "Republic of Kenya".
