Step-by-step explanation:
F.W. de Klerk held a whites-only referendum in 1992 to obtain a mandate from the white electorate on the question of ending apartheid and negotiating a new constitution that would include all races in the future government of South Africa. De Klerk believed that a referendum was necessary to show the world that a majority of the white population was willing to support the end of apartheid and the establishment of a new democratic system of government in South Africa. The referendum was held on 17 March 1992, and a majority of white voters supported the negotiation process that led to the adoption of a new constitution in South Africa in 1994.
