What series of events triggered the industrial growth in south Africa?

The industrial growth in South Africa was primarily triggered by the discovery of diamonds in Kimberley in 1867 and gold in the Witwatersrand in the 1880s, which led to an influx of investment and migration. The subsequent mining boom necessitated the development of infrastructure, such as railways and ports, to support the export of minerals. Additionally, the establishment of a strong financial sector and the influx of foreign capital fueled industrial expansion. The economic policies during the apartheid era further institutionalized these developments, leading to a more diversified industrial base over time.
