Period in the history of the former state of Southern Rhodesia
The colonial history of Southern Rhodesia is considered to be a time period 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. 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.
