The Colony and Protectorate of Kenya, commonly known as British Kenya or British East Africa, was a colony part of the British Empire located in East 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-kilometre (9.9 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 native Kenyan majority government was elected for the first time and eventually declared independence.
