In the territory of 'Southern Rhodesia' was originally referred to as 'South Zambezia' but the name 'Rhodesia' came into use in 1895. The designation 'Southern' was adopted in 1901 and dropped from normal usage in 1964 on the break-up of the Federation of Rhodesia and Nyasaland, and Rhodesia became the name of the country until the creation of Zimbabwe Rhodesia in 1979. Legally, from the British perspective, the name Southern Rhodesia continued to be used until 18 April 1980, when the name Republic of Zimbabwe was formally proclaimed. The colonial history of Southern Rhodesia lasted from the British government's establishment of the government of Southern Rhodesia on 1 October 1923, to Prime Minister Ian Smith's unilateral declaration of independence in 1965.
'Rhodesia' was named after Cecil Rhodes, the British empire-builder who was one of the most important figures in British expansion into southern Africa, and who obtained mineral rights in 1888 from the most powerful local traditional leaders through treaties such as the Rudd Concession and the Moffat Treaty signed by King Lobengula of the Ndebele. The British government agreed that Rhodes' company, the British South Africa Company (BSAC), would be granted exclusive mineral rights stretching from the Limpopo to Lake Tanganyika. Queen Victoria signed the charter in 1889. Rhodes used this document in 1890 to justify sending the Pioneer Column, a group of white settlers protected by well-armed British South Africa Police (BSAP) and guided by the big game hunter Frederick Selous, through Matabeleland and into Shona territory to establish Fort Salisbury (now Harare). In 1893–94, with the help of their new maxim guns the BSAP would go on to defeat the Ndebele in the First Matabele War, a war which also resulted in the death of King Lobengula and the death of most of the members of the Shangani Patrol. Shortly after the disastrous Jameson Raid of the BSAP into the Transvaal Republic, the Ndebele were led by their spiritual leader Mlimo against the white colonials and thus began the Second Matabele War (1896–97). After months of bloodshed, Mlimo was found and shot by the American scout Frederick Russell Burnham and soon thereafter Rhodes walked unarmed into the Ndebele stronghold in Matobo Hills and persuaded the impi to lay down their arms, effectively ending the revolt.
