The Second Boer war was essentially a war for control of the Gold and Diamond mines of the Orange Free State and the Republic of Transvaal. But following British victory and subsequent control of the mines, British mine owners instigated a tier racial system of employment to minimise the chances of any collective action of labour. The mostly British mine owners relied on cheap labour but were terrified of further conflict, of indigenous South Africans outnumbering European settlers, and of uniting of labour across racial lines to force higher wages or improved working conditions. As a result the British capitalists reserved managerial positions for the “Boer” European settlers of Dutch heritage and while heavy labour was given to black Africans. This stratification of the labour force was later accepted by the government of the Union of South Africa and inspired far-reaching legislation of racial segregation following South African independence, laying the foundation for apartheid.
