The Rand Rebellion (Afrikaans: Rand-rebellie; also known as the 1922 strike) was an armed uprising of white miners in the Witwatersrand region of South Africa, in March 1922. Jimmy Green, a prominent politician in the Labour Party, was one of the leaders of the strike. Following a drop in the world price of gold from 130 shillings (£6 10s) per fine troy ounce in 1919 to 95s/oz (£4 15s) in December 1921, the companies tried to cut their operating costs by decreasing wages, and by weakening the colour bar by promoting cheaper black mine workers to skilled and supervisory positions.
