Since the 11th century, the region that is now Zimbabwe has been the site of several organised states and kingdoms such as the Rozvi, Mutapa and Mthwakazi kingdoms, as well as being a major route for migration and trade. The British South Africa Company of Cecil Rhodes first demarcated the present territory during 1890 when they conquered Mashonaland and later in 1893 Matabeleland after a fierce resistance by Matabele people known as the First Matabele War. Company rule ended in 1923 with the establishment of Southern Rhodesia as a self-governing British colony. In 1965, the conservative white minority government unilaterally declared independence as Rhodesia.
