In 1867 diamonds were found near the Orange River, and in 1886 gold was found on the Witwatersrand in the Boer republic of the Transvaal. These discoveries turned South Africa from a farming backwater into the most valuable piece of real estate in the British Empire — and set every group in the region on a collision course.
Why minerals changed everything: Before 1867, South Africa was four separate territories (Cape Colony, Natal, Orange Free State, Transvaal) with little reason to fight over land. Diamonds and gold gave the British imperialism a reason to want control of the Boer republics, and gave the Boers a reason to resist.
- Kimberley diamond fields (1867–1871) — thousands of small diggers were bought out by big companies; by 1888 Cecil Rhodes's De Beers controlled almost the entire world diamond supply
- Witwatersrand gold (1886) — the richest goldfield on Earth, but deep-level mining needed huge capital, imported machinery, and a massive cheap labour force
- Political consequence — Britain now had a direct economic interest in a united, British-controlled South Africa instead of separate British colonies and independent Boer republics
- Social consequence — mining towns pulled in African migrant workers under the migrant labour system, the start of the pattern later used to police apartheid
- Economic consequence — mining profits needed a reliable, controlled, low-paid African workforce, which pushed employers and the state towards pass laws and land restriction decades before formal apartheid
Why war became likely
The Transvaal (South African Republic) was ruled by Boer president Paul Kruger. After gold was found, thousands of foreign miners — called Uitlanders — flooded in but were denied the vote. This gave Britain's High Commissioner, Sir Alfred Milner, a pretext for confrontation.
- Economic causes — Britain wanted control of the gold-rich Transvaal and free trade across the region, not a rival Boer economy blocking British mining capital
- Political causes — Kruger refused full voting rights to the Uitlanders; Milner used their grievances to pressure Kruger into war
- Strategic causes — Britain feared a strong, independent Transvaal could ally with a rival power (Germany had shown interest) and threaten British control of the whole region and the sea route to India
- The Jameson Raid (1895–96) — a failed British-backed attempt to overthrow Kruger by force; it hardened Boer distrust of Britain and pushed the Transvaal and Orange Free State into a defensive alliance
Rank the causes, don't just list them: Examiners reward an argument. A strong answer states which cause was most important (usually the economic causes — Britain's need for uninterrupted access to gold) and shows how the political and strategic causes fed off it, rather than treating all three as equally weighted.

War broke out in October 1899 between Britain and the two Boer republics (Transvaal and Orange Free State). It lasted three years and cost far more, in lives and money, than Britain expected.
Conventional war (1899–1900)
Boer commandos besieged British towns (Mafeking, Ladysmith, Kimberley) and won early victories. Britain sent huge reinforcements under Lord Roberts and Lord Kitchener, relieved the sieges, and captured the Boer capitals Pretoria and Bloemfontein by mid-1900.
Guerrilla war (1900–1902)
Boer fighters switched to hit-and-run raids led by generals like Louis Botha and Jan Smuts. Kitchener responded with a scorched-earth policy, burning Boer farms and herding Boer women and children into concentration camps, where roughly 26,000 died mostly from disease.
Treaty of Vereeniging (May 1902)
Facing starvation and no hope of foreign help, Boer leaders surrendered. The Boer republics became British colonies, Britain paid for reconstruction, and — crucially — the British promised eventual self-government and left the question of African and Coloured voting rights to be decided later by the whites-only colonial governments.
Sieges, then scorched earth, then surrender on Boer terms about race — that is the shape of the whole war.
The single most damaging clause: The Treaty of Vereeniging left the native franchise question (whether Black South Africans could vote) to be settled only after self-government was granted. In practice this handed the decision to white-run governments, guaranteeing Africans, Coloureds and Indians would be excluded from the political settlement that followed.
From war to Union (1902–1910)
Britain wanted the four territories merged into one stable, self-governing dominion — cheaper to defend and more attractive to investors than four separate colonies. Boer and British leaders (Botha, Smuts, and British colonial politicians) negotiated the terms.
- Act of Union (1909), in force from 1910 — merged Cape Colony, Natal, Transvaal and Orange Free State into the Union of South Africa, a self-governing British dominion
- Whites-only Parliament — the Union constitution kept voting rights for Africans almost entirely restricted to the Cape, and gave no African representation in the national Parliament
- Reconciliation of Boer and Briton — Union was designed to unite the two white communities after the war; it deliberately excluded the Black, Coloured and Indian majority from that reconciliation
- Louis Botha became the first Prime Minister, with Jan Smuts as a senior minister — both former Boer generals now running the new state
Union solved one problem and created another: The Act of Union ended white infighting between British and Boer, but it built racial exclusion into South Africa's founding constitution. Every later injustice — segregation, then apartheid — grew out of a state founded on this exclusion.

Between Union (1910) and the 1948 election, South Africa was ruled by white politicians who disagreed on Boer-versus-British questions but broadly agreed on keeping Black South Africans out of political power and off the best land. This period is called segregation.
Louis Botha & Jan Smuts (South African Party, to 1924)
- Prioritised reconciling Boer and British whites and staying loyal to the British Empire
- Natives Land Act (1913) — banned Africans from buying or renting land outside designated reserves, about 7–8% of the country
- Used the army to crush the 1922 Rand Rebellion (white miners' strike) — showed the state would use force against white workers too, not only Africans
- Smuts represented South Africa abroad (helped found the League of Nations) while segregation deepened at home
J.B.M. Hertzog (National Party, PM 1924–1939)
- Champion of Afrikaner nationalism; pushed for full independence from Britain and Afrikaans-language rights
- Pact Government (1924) with the Labour Party — protected white workers' jobs from cheaper Black labour ('civilized labour' policy)
- Hertzog Bills / Representation of Natives Act (1936) — removed the remaining African voters in the Cape from the common voters' roll, replacing it with a toothless separate Natives' Representative Council
- Continued and extended land segregation started under the 1913 Land Act
| Law / policy | Year | Effect |
|---|---|---|
| Natives Land Act | 1913 | Confined African land ownership to reserves; forced many into wage labour or tenant farming on white land |
| Pact Government 'civilized labour' policy | 1924 | Reserved better-paid jobs for whites; pushed Black workers into the lowest-paid roles |
| Representation of Natives Act | 1936 | Ended African voting on the common roll in the Cape, the last remaining African franchise |
| Native Trust and Land Act | 1936 | Slightly expanded the reserves (to about 13%) but tightened control over African land use |
Protest against these laws grew steadily, even though it had not yet radicalised into mass action. The South African Native National Congress was founded in 1912 (renamed the African National Congress in 1923) to protest peacefully — through petitions, delegations to London, and appeals to the courts — against the Land Act and the erosion of African rights.
Protest before 1948 was legal and cautious: Early ANC leaders such as John Dube (its first president) believed in working within the system: petitions, deputations, and appeals to British fairness. This approach achieved almost nothing against a government determined to segregate, which is exactly why a new, more radical generation of leaders would later push for change (a story covered in the second half of this section).
Don't confuse segregation with apartheid: Segregation (1910–1948) restricted African rights piecemeal, law by law, mostly over land and labour and the vote. Apartheid, introduced after 1948, was a far more total and systematic ideology covering every part of life. Segregation built the foundations; apartheid built the whole structure on top.
