North-Western Rhodesia, in south-central Africa, was a territory administered from 1891 until 1899 under charter by the British South Africa Company.
In 1890 the British South Africa Company signed a treaty with King Lewanika of the Barotse, one of the most powerful traditional rulers in the territory.
Nonetheless, the charter gave the territory protection.
The territory consisted of the western half of present-day Zambia up to the Kafue River, which is its border with North-Eastern Rhodesia.
Later, the border between the two chartered territories was moved east, but the distinction had no great implications.
