The Colony and Protectorate of Kenya, commonly known as British Kenya, was part of the British Empire in Africa. 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 (10 mi) 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.
