Rhodesia, known initially as Zambesia, is a historical region in southern Africa whose formal boundaries evolved between the 1890s and 1980. Demarcated and named by the British South Africa Company (BSAC), which governed it until the 1920s, it thereafter saw administration by various authorities. It was bisected by a natural border, the Zambezi. The territory to the north of the Zambezi was officially designated Northern Rhodesia by the company, and has been Zambia since 1964; that to the south, which the company dubbed Southern Rhodesia, became Zimbabwe in 1980. Northern and Southern Rhodesia were sometimes informally called "the Rhodesias". The term "Rhodesia" was first used to refer to the region by White settlers in the 1890s who informally named their new home after Cecil Rhodes, the company's founder and managing director. It was used in newspapers from 1891 and was made official by the company in 1895. To confuse matters, Southern Rhodesia, which became a self-governing colony of the United Kingdom in 1923, referred to itself simply as "Rhodesia" from 1964 to 1979, and in 1965 unilaterally declared independence under that name. It thereafter briefly renamed itself "Zimbabwe Rhodesia" in 1979. The usage of the term Rhodesia to refer to the historical region fell from prominence after Northern Rhodesia became Zambia in 1964. From then until 1980, "Rhodesia" commonly referred to Southern Rhodesia alone. Since 1980 the term has not been in general use, aside from in a historical context. Etymology When whites settled what became "Southern Rhodesia" in 1890, and when the British South Africa Company was chartered to administer "North-Western Rhodesia" and "North-Eastern Rhodesia", it was not under those names, but the names of the parts—"Mashonaland", "Matabeleland", "Barotseland", and so on. The territories were initially collectively referred to as "Zambesia" (Cecil Rhodes's preferred name), "Charterland" (Leander Starr Jameson's proposal) or "the BSAC territories". "Rhodesia" was used informally by the settlers from the start of white settlement, and was common enough usage for newspapers to start using it in articles in 1891. In 1892 it was used for the name of the first newspaper in Salisbury, The Rhodesia Herald. The BSAC officially adopted the name "Rhodesia" in May 1895, and the British government followed in 1898. "It is not clear why the name should have been pronounced with the emphasis on the second rather than the first syllable," Robert Blake comments, "but this appears to have been the custom
