North-Western Rhodesia, in south central Africa, was formed and administered from 1891 under charter by the British South Africa Company, which in 1890 had signed a treaty with King Lewanika of the Barotse, the most powerful traditional ruler in the territory. Although it had features of a charter colony, the treaty and charter gave the territory protectorate status (although not as an official protectorate of the British government.
The territory consisted of the western half of present-day Zambia up to the Kafue River, its border with North-Eastern Rhodesia. Later the border between the two chartered territories was moved east, but the distinction did not have any great implications.
