Barotziland–North-Western Rhodesia was a British protectorate in south central Africa formed in 1899. It encompassed North-Western Rhodesia and Barotseland. The protectorate was administered under charter by the British South Africa Company. It was the largest of what were colloquially referred to as the three Rhodesian protectorates, the other two being Southern Rhodesia and North-Eastern Rhodesia. It was amalgamated with North-Eastern Rhodesia, another territory administered by the British South Africa Company, to form Northern Rhodesia in 1911.
