The Colony and Protectorate of Kenya was part of the British Empire in Africa from 1920 until 1963. It was established when the former East Africa Protectorate was transformed into a British Crown colony in 1920. Technically, the 'Colony of Kenya' referred to the interior lands, while a 16 km coastal strip (nominally on lease from the Sultan of Zanzibar) was the 'Protectorate of Kenya' but the two were controlled as a single administrative unit. The colony came to an end in 1963 when a black majority government was elected for the first time and eventually declared independence as Kenya.
The Colony and Protectorate 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 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.
