The British South Africa Company's administration of what became Rhodesia was chartered in 1889 by Queen Victoria of the United Kingdom, and began with the Pioneer Column's march north-east to Mashonaland in 1890. Empowered by its charter to acquire, govern and develop the area north of the Transvaal in southern Africa, the Company, headed by Cecil Rhodes, raised its own armed forces and carved out a huge bloc of territory through treaties, concessions and occasional military action, most prominently overcoming the Matabele army in the First and Second Matabele Wars of the 1890s. By the turn of the century, Rhodes's Company held a vast, land-locked country, bisected by the Zambezi river. It officially named this land Rhodesia in 1895, and ran it until the early 1920s.
The area south of the Zambezi became Southern Rhodesia, while that to the north became North-Western and North-Eastern Rhodesia, which were joined in 1911 to form Northern Rhodesia. Within Northern Rhodesia, there was a separate Kingdom called Barotseland which later became a British protectorate alongside other territories under the British sphere of influence. Each territory was administered separately, with an administrator heading each territorial legislature. In Southern Rhodesia, which attracted the most white immigrants and developed fastest, a legislative council was established in 1898. This comprised a blend of Company-nominated officials and elected members, with the numbers of each fluctuating over time.
