East Africa was an administrative grouping of five separate British territories: Kenya, Uganda, the Sultanate of Zanzibar and British Somaliland.
The common interest of Kenya, Tanganyika and Uganda invited cooperation in economic matters and consideration of political union. The territorial governors, organized as the East Africa High Commission, met periodically to administer such common activities as taxation, industrial development and education.
The authority of the Commission did not infringe upon the constitution and internal autonomy of the individual colonies. A common coinage and banknotes, which were also legal tender in Aden, were provided for use of the member colonies by the East Africa Currency Board. The coinage through 1919 had the legend "East Africa and Uganda 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 a 16-kilometre-wide (10 mi) coastal strip that became the Kenya protectorate.
