Before 1867, southern Africa was a patchwork of small farming societies — Boer republics, African kingdoms, and a British colony at the Cape. Nobody was rich. Nobody was powerful enough to dominate the whole region. Then everything changed.
In 1867 a huge diamond was found near the Orange River. Within a few years, thousands of prospectors had flooded into the town that became Kimberley. Then in 1886, an even bigger discovery hit: gold on the Witwatersrand (Witwatersrand), in the Boer republic of the Transvaal. This double shock — diamonds then gold — is called the Mineral Revolution.
Why this matters for the whole unit: The Mineral Revolution is the hinge on which the rest of South African history turns. It created the wealth, the racial labour system, and the political rivalries that led to the South African War — and it planted the economic segregation that later hardened into apartheid.
The economic effects were staggering. Kimberley's diamond mines needed deep-level machinery and huge amounts of capital, so small diggers were bought out by a handful of powerful companies. By 1889, Cecil Rhodes's De Beers Consolidated Mines controlled nearly all diamond production in the world. On the Witwatersrand, gold mining needed even more capital because the gold was low-grade and buried deep — so a small group of financiers, the so-called Randlords, came to dominate the new industry.
- Urbanisation — Kimberley and then Johannesburg (founded 1886) grew from nothing into booming cities within a decade.
- Railways and infrastructure — lines were built to move machinery in and ore out, linking the interior to coastal ports for the first time.
- A shift in economic power — the Transvaal, once a poor Boer farming republic, suddenly sat on the richest goldfield in the world.
- Foreign investment — British and European capital poured in, giving outside powers a direct financial stake in the Transvaal's future.
So the Mineral Revolution didn't just create wealth — it rearranged who held power in the region, and made the Transvaal a prize worth fighting over.

Gold on the Witwatersrand pulled in a flood of white migrants — engineers, prospectors, and fortune-seekers, mostly British. The Transvaal Boers called them Uitlanders (Uitlanders). Within a few years, Uitlanders on the Rand actually outnumbered Transvaal Boers.
The Uitlander grievance: President Paul Kruger's Transvaal government taxed the gold industry heavily but refused Uitlanders full political rights — voting required 14 years' residence. Uitlanders had no vote but paid most of the state's taxes. This "no taxation without representation" grievance became Britain's excuse to interfere in Transvaal affairs.
For the Boers, this wasn't stubbornness — it was survival instinct. If Uitlanders got the vote, their numbers meant they would soon control the Transvaal Volksraad (Volksraad) and hand the republic to Britain by ballot rather than by war. So Kruger's refusal to compromise hardened into a symbol of Boer nationalism: the determination to keep an independent, Afrikaner-run republic, protected from British and capitalist control.
The British/Uitlander view
- Uitlanders paid the taxes that funded the state but had no vote — basic injustice.
- Kruger's government was corrupt and inefficient, run for Boer farmers' benefit.
- British "paramountcy" in southern Africa was threatened by a rich, independent Transvaal.
The Boer view
- Enfranchising Uitlanders quickly would let outsiders vote away Boer independence.
- The republic had the right to protect itself from being swallowed by British/capitalist interests.
- Britain's real goal was not fairness but control of the goldfields.
Meanwhile, a different migration was reshaping African lives. Thousands of African men left rural homesteads to work in the mines, often walking hundreds of kilometres or arriving under recruitment schemes. Mine work offered wages, but it also pulled men away from their homes for months at a time, weakening rural economies and family life.
- Compound system — African miners were housed in fenced, guarded compounds close to the mine, cut off from surrounding towns and separated from their families.
- Pass laws — Africans had to carry documents controlling where they could live and work, an early tool of racial control.
- Low, fixed wages — a colour bar reserved skilled, better-paid jobs for whites, while African labour stayed cheap and unskilled by law and custom.
- Urban growth — African migration also built the African townships that grew up alongside Kimberley and Johannesburg, even though residents had few rights there.
So the same event — the discovery of gold — pulled two very different groups towards the same cities, for very different reasons and with very different outcomes.

Mine owners wanted to keep costs as low as possible, and African labour was the cheapest they could find. Wages for African miners were kept far below those of white miners doing similar or even lower-skilled work.
Recruitment
Labour agencies recruited African men from as far as Mozambique and the Cape, often through debt or tax pressure — colonial hut taxes forced many men to seek wage work just to pay them.
Control
Once on the mine, workers lived in compounds, were searched to prevent diamond theft, and had almost no freedom of movement — an early template for later apartheid controls.
The colour bar
Skilled and supervisory jobs were reserved for whites by informal custom and later by law, locking Africans into the lowest-paid, most dangerous work underground.
Recruit, control, restrict — the mines built segregation's blueprint decades before apartheid had a name.
Link this to the bigger picture: Examiners want you to show that segregation did NOT begin with apartheid in 1948. The compound system, pass laws, and colour bar on the mines from the 1870s–1890s were the beginnings of segregation — practical answers to a labour problem that hardened over decades into official government policy.
By the late 1890s, tension between Britain and the Transvaal had become a crisis. Sir Alfred Milner, Britain's High Commissioner in South Africa, pushed hard for Uitlander rights, partly because he genuinely believed in British supremacy in the region. Kruger offered small concessions, but Milner kept raising the demands.
| Cause | Explanation |
|---|---|
| Economic | Britain wanted secure access to the Transvaal's gold and control over the region's economy; Randlords wanted cheaper labour and fewer state restrictions. |
| Political | Britain wanted to assert "paramountcy" (supreme authority) over all of southern Africa; the Transvaal wanted to remain fully independent. |
| The Uitlander question | Used by Milner as the public justification for pressuring, and ultimately threatening, the Transvaal. |
| Personal/ideological | Milner and Kruger were both inflexible; neither was willing to back down without a fight. |
Historians still debate which cause mattered most. Some stress economic imperialism — Britain and the Randlords needed control of the goldfields. Others stress strategic/political motives — Britain could not tolerate a rival, independent, potentially hostile republic sitting on the road to its empire in the rest of Africa. Most agree it was a mix of both, with the Uitlander issue used as the trigger.
Talks collapsed in 1899. On 11 October, the Transvaal and its ally the Orange Free State declared war first, hoping to strike before British reinforcements arrived. The South African War (also called the Second Boer War) had begun.
