Union of South Africa

• 1. Introduction

  ›

  On the 31st of May 1910, four British colonies dissolved themselves to form something new: the Union of South Africa. The Cape Colony, Natal, the Transvaal, and the Orange River Colony each surrendered their own parliaments that day, folding into a single unitary state on the southern tip of Africa. It was a political experiment built on a paradox. The new nation was simultaneously a self-governing dominion of the British Empire and a country where the vast majority of its people had no meaningful voice in their own governance. The story of the Union stretches from the ruins of the Second Boer War to the racially charged referendum of 1960, and it asks a question that haunted every decade of its existence: who, exactly, did this union serve?

• 2. Failed First Attempts

  ›

  Sir George Grey, Governor of the Cape Colony from 1854 to 1861, first championed the idea of a united South Africa. He argued that political divisions among white-controlled states weakened them against African peoples, risked an ethnic split between British settlers and Boers, and left the Cape exposed to interference from rival European powers. The Orange Free State cautiously agreed. The Transvaal seemed likely to follow. But the British Colonial Office ordered Grey to stop, and his refusal to back down eventually got him recalled to London.

  Two decades later, in the 1870s, the London Colonial Office tried again under Lord Carnarvon, Secretary of State for the Colonies. This time, the plan was confederation, the model used in Canada. Southern African leaders rejected it almost unanimously. The Orange Free State refused to even discuss it. Cape Prime Minister John Molteno called the idea badly informed and irresponsible. Local leaders resented that the scheme had been designed from the outside, without any understanding of the wildly different sizes, economies, and political systems among the states involved.

  The Cape Colony responded with its own counter-proposal in 1877, now known as the Molteno Unification Plan. It was a unitary model, locally driven, that would extend the Cape's multiracial franchise to smaller states as they gradually joined through a system of treaties. Britain rejected it. Lord Carnarvon preferred the confederation model he already knew, and he pushed ahead with it. The result was a string of destructive wars across southern Africa. Those conflicts eventually fed into the first and second Anglo-Boer Wars, with consequences that reshaped the entire subcontinent.

• 3. War and Its Aftermath

  ›

  Gold discovered in the 1880s drew thousands of British immigrants to the mines of the Transvaal Republic and the Orange Free State. The Afrikaner political establishment called these newcomers "uitlanders," taxed them heavily, and denied them the right to vote. The British government, protective of its citizens and interested in the mines, demanded reforms. Those demands were rejected. A private British attempt to overthrow Transvaal President Paul Kruger, known as the Jameson Raid of 1895, failed badly and made war more likely.

  The Second Boer War began on the 11th of October 1899. In the final months of that year, Boer forces besieged the British-held towns of Ladysmith, Kimberley, and Mafeking, and won engagements at Colenso, Magersfontein, and Stormberg. British Prime Minister Lord Salisbury and Colonial Secretary Joseph Chamberlain had ignored warnings that Boer forces were stronger than earlier reports suggested. Britain recovered, eventually deploying roughly 400,000 soldiers from across its colonial empire and lifting all three sieges.

  The guerrilla phase that followed was the most brutal part of the conflict. Afrikaner civilians were interned in concentration camps in which roughly 28,000 people died. Homesteads were burned to deny guerrilla fighters a base of support. The British combined this scorched-earth campaign with a network of blockhouses to track down holdouts. The war ended with the Treaty of Vereeniging in 1902, which formally annexed the Boer republics into the Cape Colony. Eight years later, those same territories would be negotiating as equal partners in the convention that created the Union.

• 4. Drafting the Constitution

  ›

  The National Convention met across three cities and three sessions between October 1908 and May 1909. Delegates gathered first in Durban from the 12th of October to the 5th of November 1908, then in Cape Town through early February 1909, and finally in Bloemfontein from the 3rd to the 11th of May 1909. All 33 delegates worked behind closed doors. The organizers feared that a public process would prevent delegates from compromising on the most divisive questions.

  What emerged was a unitary state, not the federation model used in Canada and Australia. Each colony's parliament was abolished and replaced with a provincial council. A bicameral legislature was created, with a House of Assembly and a Senate. Cape Prime Minister John X. Merriman fought hard, but ultimately without success, to extend the Cape Colony's multiracial franchise to the other colonies. His effort failed. The constitution instead entrenched the Cape Qualified Franchise as it existed, while leaving the rest of South Africa to vote on a white-only basis.

  Pretoria became the seat of government. Parliament sat in Cape Town. The Appellate Division was based in Bloemfontein. Louis Botha, who had commanded Boer forces as a general just years earlier, was appointed the Union's first prime minister, heading a coalition drawn from the Afrikaner and English-speaking communities.

• 5. Sovereignty and the Crown

  ›

  Louis Botha led a country that was legally self-governing but still deeply tied to Britain. The Balfour Declaration of 1926 and the Statute of Westminster, passed by the British Parliament in December 1931, changed that. The Statute repealed the Colonial Laws Validity Act 1865 and confirmed that the Union and its fellow dominions were equal in status to the United Kingdom. Westminster could no longer legislate on their behalf.

  South Africa's parliament went further. The Status of the Union Act, passed in 1934, incorporated the relevant provisions of the Statute of Westminster directly into South African law. It stripped away whatever authority Whitehall had retained to legislate for South Africa and ended the nominal British role in granting Royal Assent. From that point, the governor-general signed or vetoed bills passed by the South African parliament without any option to seek London's guidance.

  The Statute of Westminster also had a more immediate practical effect. It freed the South African Parliament from certain restrictions on handling what official documents called the "native question." The new latitude was used to tighten racial controls, not loosen them. The coloured-vote constitutional crisis of the 1950s traced directly back to that unlocked power, when Parliament removed the right of coloured voters to participate in the main assembly and replaced it with a separate, segregated, and largely powerless body.

• 6. Borders and Borderlands

  ›

  From 1874, leaders of several Indigenous peoples in the territory now known as Namibia approached the Cape Parliament seeking accession. Maharero of the Herero nation was among those leaders. They were already facing Portuguese encroachment from the north and Afrikaner encroachment from the south, and they calculated that absorption into the Cape Colony, with its multiracial franchise and legal protections for land rights, was preferable to annexation by Portugal or Germany. The Cape Parliament sent William Palgrave to negotiate. Some nations, including the Damara and the Herero, responded positively in October 1876. Britain ultimately blocked formal incorporation, allowing only the port of Walvis Bay to be absorbed as an exclave under the magisterial district of Cape Town. Germany established a protectorate over the rest in 1884.

  After the outbreak of the First World War in 1914, Union forces occupied German South West Africa. When the League of Nations was established, South Africa was granted a Class C Mandate to administer the territory. The Union treated it almost as a fifth province in practice, though it was never formally annexed. In 1949, South Africa passed a law giving South West Africa representation in the South African parliament. When the United Nations later invited South Africa to prepare a Trusteeship agreement, the Union refused, and the resulting legal dispute was still unresolved when the republic replaced the Union in 1961.

  The Southern Rhodesia referendum of 1922 presented a different kind of boundary question. When the British South Africa Company's rule became impractical, Rhodesian voters chose between responsible self-government and joining the Union. Politician Sir Charles Coghlan warned that membership in the Union would make Southern Rhodesia the "Ulster of South Africa." The vote went 59.4% for a separate colony and 40.6% for joining, keeping Rhodesia out.

• 7. Race and Power

  ›

  The South Africa Act 1909 addressed race in two explicit provisions. The first preserved the Cape Qualified Franchise, a system that had operated without racial restrictions, though socioeconomic barriers meant non-white political participation was extremely limited in practice. The second made "native affairs" the responsibility of the national government, creating the office of Minister of Native Affairs.

  Sports were segregated in practice long before the law caught up. White-only teams were the norm well before a 1956 law formally required racial separation. Black athletes competed through separate bodies such as the South African Soccer Federation, while white athletes belonged to the South African Football Association. The Union participated in every Summer Olympics from 1912 to 1960 and one Winter Olympics, also in 1960. After those games, South Africa was barred from Olympic competition until 1992 for excluding black athletes.

  The film industry followed similar lines. Studios such as African Film Productions and Killarney Film Studios, both established by I.W. Schleisner, produced almost exclusively white-made films. The National Censorship Act of 1931 introduced formal pre-approval requirements for film content. Films in the 1930s were predominantly Afrikaner nationalist in character. The industry remained largely independent until the mid-to-late 1950s, when 75% of it was acquired by 20th Century Fox over the course of three years.

• 8. The Republic Referendum

  ›

  By the late 1950s, the fault line between English-speaking and Afrikaans-speaking whites had hardened into a direct constitutional question: should South Africa become a republic and leave the Commonwealth? Most English-speaking South Africans supported the United Party of Jan Smuts, which favored close ties with Britain. The Afrikaans-speaking National Party had long held anti-British sentiments and had opposed South African involvement in the Second World War. Some National Party-aligned organizations, including the Ossewabrandwag, had openly supported Nazi Germany during the war.

  The referendum was held on the 5th of October 1960. Most English-speaking whites voted against. In Natal, which had an English-speaking majority, some whites called for secession from the Union after the results came in. Five years earlier, some 33,000 Natalians had signed the Natal Covenant in opposition to any plan for a republic. But the Afrikaans-speaking electorate was simply larger. The referendum passed.

  On the 31st of May 1961, exactly fifty-one years after the Union was proclaimed, the Republic of South Africa came into being under a new constitution that repealed the South Africa Act 1909. The National Party government withdrew South Africa from the Commonwealth. Most features of the Union's constitutional structure carried over to the republic with very little change. South Africa would not rejoin the Commonwealth until the 1st of June 1994, thirty-three years later.
