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' 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.
