Administrative posts of the British South Africa Company in Southern Rhodesia

The British South Africa Company appointed a variety of officials to govern Southern Rhodesia (called Zimbabwe since 1980) between 1890 and 1923. The most prominent of these were the Administrator and the Chief Magistrate, the first of which was in effect the head of government during this time. As such, he held a seat on the Legislative Council of Southern Rhodesia "ex officio".
The post of Administrator was officially created by section 8 of the Southern Rhodesia Order in Council of 1894, but in practice had existed as a deputy to the Chief Magistrate, who was the principal officer from 1890. The term of office was theoretically three years, though it was common to reappoint incumbents. There was, in addition, an Acting Administrator, who was a deputy.
The Administrator office became defunct when Southern Rhodesia received responsible government within the British Empire in October 1923. It was replaced by the post of Premier, which was renamed Prime Minister in 1933.
Resident Commissioner.
After the Jameson Raid, the British Imperial Government determined by order in council to appoint a Resident Commissioner to supervise the affairs of the British South Africa Company. Reporting to the High Commissioner for Southern Africa, who in turn reported to the Colonial Office in London, the resident commissioner's function was to protect African interests and to prevent the company from inducing another expensive rebellion.
