Before 1902, the southern part of Africa that is now South Africa was under the hegemony of Great Britain. There also were two self-proclaimed independent states: Transvaal (also known as the South African Republic), and the Orange Free State. The British and the Boers fought two wars, known as the First Boer War (1880–1881) and the Second Boer War (1899–1902); after the second war, in which the British prevailed, both republics were incorporated into the British Empire. On May 31, 1910, the two ex-republics and the British colonies of the Cape and Natal formed the Union of South Africa, a self-governing dominion of the British Empire.
The United States appointed its first envoy to South Africa, Ralph J. Totten, in 1929. He was appointed as Minister Resident/Consul General and promoted to Envoy Extraordinary and Minister Plenipotentiary the following year.
South Africa was renamed the Republic of South Africa on May 31, 1961, after links to the British crown were severed.
Political appointee A person who is not a career foreign service officer, but is appointed by the president (often as a reward to political friends).
Appointed The date that the ambassador took the oath of office; also known as "commissioning". It follows confirmation of a presidential appointment by the Senate, or a Congressional recess appointment by the president. In the case of a recess appointment, the ambassador requires subsequent confirmation by the Senate to remain in office.
Presented credentials The date that the ambassador presented his letter of credence to the head of state or appropriate authority of the receiving nation. At this time the ambassador officially becomes the representative of his country. This would normally occur a short time after the ambassador's arrival on station. The host nation may reject the ambassador by not receiving the ambassador's letter, but this occurs only rarely.
Terminated mission Usually the date that the ambassador left the country. In some cases a letter of recall is presented, ending the ambassador's commission, either as a means of diplomatic protest or because the diplomat is being reassigned elsewhere and replaced by another envoy.
Chargé d'affaires The person in charge of the business of the embassy when there is no ambassador commissioned to the host country.
Ad interim Latin phrase meaning "for the time being", "in the meantime".
Note: The ambassadors were commissioned to the Union of South Africa until 1961 when South Africa became a republic.
South Africa became a republic on May 31, 1961. This required a new commission for the ambassador. Hereafter ambassadors were commissioned to the Republic of South Africa.
