What is now the State of the Nation Address has its origins in the speech from the throne (in Afrikaans staatsrede meaning “state reasoning/rationale”) setting out the Government’s legislative programme for the year. The high point of the State Opening of Parliament, it was originally given by the Governor-General (or, in 1947, by the King of South Africa himself) but with the abolition of the monarchy in 1961 the sovereign’s vice-regal representative was abolished and replaced by the Staatspresident as chief officer of the South African state.
Giving a speech from an actual throne was considered too monarchic for a republican polity, so – like in the Boer republics of old – presidents gave their staatsredes standing. Here, State-President Fouché is flanked by the chiefs of the defence staff and police, the Serjeant-at-Arms with the mace, and the Gentleman Usher of the Black Rod.
Of course, much of this was abolished in the 1980s with the constitutional innovations as a last-ditch attempt to entrench apartheid. South Africa is now on its third constitution since the above photo was taken.
It reminds me of how in Ireland almost all the traditions of the Viceroy (viz. the Viceregal Guard of Battleaxes, etc.) were abolished not by the Saorstát or Éire but by the British themselves – in their case by penny-pinching Victorians who found Dublin an easy target for cost-cutting.
