The Mineral Revolution is a term used by historians to refer to the rapid industrialisation and economic changes which occurred in South Africa from the 1860s onwards. The Mineral Revolution was largely driven by the need to create a permanent workforce to work in the mining industry, and saw South Africa transformed from a patchwork of agrarian states to a unified, industrial nation. In political terms, the Mineral Revolution had a significant impact on diplomacy and military affairs. Finally, the policies and events of the Mineral Revolution had an increasingly negative impact on race relations in South Africa, and formed the basis of the apartheid system, which dominated South African society for a century. The Mineral Revolution was caused by the discovery of diamonds in Kimberly in 1867 and also by the discovery of gold in Witwatersrand in 1886. The mineral mining revolution laid the foundations of racial segregation and the control of white South Africans over black South Africans. The Mineral Revolution changed South Africa from being an agricultural society to becoming the largest gold producing country in the world. Economics Mining The Mineral Revolution began with the discovery of diamonds at the town of Kimberley in 1867. The discovery of diamonds led to a rush of prospectors descending on the town, whose population skyrocketed as increasing numbers of prospectors arrived to seek their fortune. As more diggers arrived in Kimberley, diamond-mining increased in scale, focusing in open-pit mining of three main sites. As surface deposits of diamonds were excavated, deeper pits had to be dug, propelling the Mineral Revolution into a new phase. To excavate deep deposits of diamonds, diggers needed machinery (particularly steam engines), credit, and a large labour force. These were unavailable to ordinary diggers, and the diamond mines were quickly taken over by the "mining capitalists" – large corporations with access to credit, machinery, and labour. The discovery of gold at the Witwatersrand orefields in 1886 triggered a gold rush which greatly escalated this continuing trend. The orefields, which overlapped British and Afrikaner territory, were quickly excavated of all surface deposits and a similar pattern to Kimberley emerged – small diggers were bought out by large corporations. At Kimberley, the diamond mines fell under the monopoly of De Beers, while at the Rand orefields, land was bought up by Wernher, Breit & Eckstein, Consolidated Gold Mines Inc., and a number of smaller companies.
