Republicanism had long been a plank in the platform of the ruling National Party. However, it was not until 1960, 12 years after it took power, that it was able to hold a referendum on the issue. A narrow majority—52 percent— of the minority white electorate voted in favour of abolishing the monarchy and declaring South Africa a republic. The Republic of South Africa was proclaimed on 31 May 1961. Charles Robberts Swart, the last Governor-General, was sworn in as the first State President. The title 'State President' was originally used for the head of state of the Boer Republics, and like them, the holder of the office wore a sash with the Republic's coat of arms. He was elected to a seven-year term by the Parliament of South Africa, and was not eligible for re-election. The National Party decided against having an executive presidency, instead adopting a minimalist approach as a conciliatory gesture to English-speaking whites who were opposed to a republic. As such, the State President performed mostly ceremonial duties, and was bound by convention to act on the advice of the Prime Minister and the cabinet. In practice, the post of State President was a sinecure for retired National Party ministers, as the Governor-General's post had been since 1948. Consequently, all State Presidents from 1961 to 1984 were white, Afrikaner, male, and over 60.
Executive post
Following constitutional reforms, in 1984, the office of State President became an executive post, as in the United States. The Prime Minister's post was abolished, and its powers were de facto merged with those of the State President. He was elected by an electoral college of 88 members—50 Whites, 25 Coloureds, and 13 Indians–from among the members of the Tricameral Parliament. The members of the electoral college were elected by the respective racial groups of the Tricameral Parliament—the white House of Assembly, Coloured House of Representatives and Indian House of Delegates. He held office for the Parliament's duration—in practice, five years. The last Prime Minister, P. W. Botha, was elected as the first executive State President. The State President was vested with sweeping executive powers—in most respects, even greater than those of comparative offices like the President of the United States. He had sole jurisdiction over matters of "national" concern, such as foreign policy and race relations. He was chairman of the President's Council, which resolved disputes between the three chambers regarding "general affairs" legislation. This body consisted of 60 members – 20 members appointed by the House of Assembly, 10 by the House of Representatives, five by the House of Delegates and 25 directly by the State President. Although the reforms were billed as a power-sharing arrangement, the composition of the electoral college and President's Council made it all but impossible for the white chamber to be outvoted on any substantive matter. Thus, the real power remained in white hands—and in practice, in the hands of the National Party, which had a large majority in the white chamber. As Botha was leader of the National Party, the system placed nearly all governing power in his hands. Botha resigned in 1989 and was succeeded by F. W. de Klerk, who oversaw the transition to majority rule in 1994.
Under South Africa's first non-racial constitution, adopted in 1994, the head of state is known simply as the President. However, since the declaration of the republic in 1961, most non-South African sources had referred to the State President as simply the "President". The leader of the African National Congress, Nelson Mandela, was sworn in as President on 10 May 1994.
