The South African referendum of 1992 was held on 17 March 1992 in South Africa. In it, white South Africans were asked to vote in the country's last whites-only referendum to determine whether or not they supported the negotiated reforms begun by State President F.W. de Klerk two years earlier. The result of the election was a large victory for the "yes" side.
This political intervention lead to the democratic elections held in 1994 and the inauguration of the first democratically elected President of SA, Nelson Mandela.....think that this was significant in SA history.
