In short
When did Britain take over South Africa?
Britain seized the Cape of Good Hope in September 1795, handed it back to the Dutch in 1803, and took it permanently in January 1806. Dutch sovereignty was formally ceded by the Anglo-Dutch Treaty of 1814. British control spread outward over the next century — Natal in 1843, the Boer republics after the war of 1899–1902 — and was welded into the Union of South Africa in 1910, a self-governing British dominion for whites only.
The date people usually want is 1806. It is the right answer to a narrow question — when did the British take the Cape and keep it — and the wrong answer to the larger one, because Britain did not take over South Africa in a year. It took over an existing Dutch settler colony in two military strokes, then spent a century annexing the rest by treaty, frontier war and conquest[1].

Chronology
The British takeover, date by date
1652
The Dutch East India Company (VOC) founds a refreshment station at the Cape under Jan van Riebeeck. The colony Britain later takes already exists.
1795
Britain lands at Simon's Town, defeats the VOC garrison at Muizenberg, and takes the Cape on 16 September — a wartime move against Napoleonic France.
1803
Under the Treaty of Amiens the Cape is handed to the Batavian Republic. British rule pauses for three years.
1806
Britain returns. The Battle of Blaauwberg (8 January) ends Dutch rule at the Cape for good.
1814
The Anglo-Dutch Treaty formally cedes the Cape to Britain. The occupation becomes a colony in law.
1820
Around 4,000 British settlers are planted on the eastern frontier as a buffer against the Xhosa.
1834
Slavery is abolished at the Cape; some 36,000 enslaved people are freed under a four-year 'apprenticeship'.
1843
Britain annexes Natal, extending control up the eastern seaboard.
1867 / 1886
Diamonds at Kimberley, gold on the Witwatersrand. The motive for British control shifts from the sea route to extraction.
1877–1879
Annexation of the Transvaal and the Anglo-Zulu War: the Zulu kingdom is destroyed as an independent power.
1880–81
First Boer War. The Transvaal wins back self-government.
1899–1902
Second Boer War. Kitchener's scorched-earth campaign interns roughly 115,000 Boer and Black civilians in camps; approximately 28,000 Boers and at least 20,000 Black Africans die.
1902
Treaty of Vereeniging. The Boer republics become British colonies.
1910
Union of South Africa — Cape, Natal, Transvaal and Orange River Colony merged as a British dominion, franchise restricted to whites.
1913
Natives Land Act: roughly 67% of the population is confined to about 7% of the land.
1961
South Africa becomes a republic and leaves the Commonwealth.
1994
First non-racial elections. Colonial rule ends for the majority, 342 years after 1652.
Why
Why Britain took the Cape — twice
The first two seizures had nothing to do with South Africa. They were about the sea lane to India. A hostile power at the Cape could choke British trade with Asia, so when the Netherlands fell into the French orbit in 1795, Britain took the harbour. When the Treaty of Amiens collapsed, it took it again — and this time did not give it back[2].
What turned a naval waystation into one of the most intensively exploited colonies on earth was geology. Diamonds at Kimberley in 1867 and gold on the Witwatersrand in 1886 required deep-level mining, which required enormous quantities of cheap labour under legal discipline. The pass laws, the migrant-labour compounds and the racialised wage scale were built to supply it — and were inherited wholesale by the Union in 1910 and the apartheid state in 1948.

Questions
Frequently asked
- When did Britain take over South Africa?
- Britain first seized the Cape of Good Hope from the Dutch in September 1795, after the Battle of Muizenberg. It handed the colony back to the Batavian Republic under the 1803 Treaty of Amiens, then retook it permanently in January 1806 at the Battle of Blaauwberg. Dutch sovereignty was formally ceded to Britain by the Anglo-Dutch Treaty of 1814. British control was extended across the region over the following century and consolidated in the Union of South Africa in 1910.
- When did the British take over the Cape Colony?
- Twice: temporarily in 1795 and permanently in 1806. The first occupation lasted from 1795 to 1803 and was a wartime measure against Napoleonic France; the second, from 1806, became lasting colonial rule and was recognised in international law by the Anglo-Dutch Treaty of 1814.
- How long did Britain rule South Africa?
- From 1806 to 1910 as a set of directly governed colonies (the Cape, Natal, and after 1902 the Transvaal and Orange River Colony), and from 1910 to 1961 as the Union of South Africa, a self-governing British dominion. Full legal separation came when South Africa left the Commonwealth and became a republic in 1961 — but the government was white-minority throughout, and majority rule only arrived in 1994.
- Did Britain or the Netherlands colonise South Africa first?
- The Netherlands. The Dutch East India Company (VOC) established a refreshment station at the Cape of Good Hope in 1652 under Jan van Riebeeck, 143 years before the first British seizure. Britain took over an existing settler colony rather than founding one.
- Why did Britain want South Africa?
- Initially for the sea route: the Cape controlled the passage to India, and Britain took it in 1795 and 1806 to keep it out of French hands. From the 1860s the motive became extraction — diamonds at Kimberley in 1867 and gold on the Witwatersrand in 1886 turned the region into an industrial mining economy that depended on cheap, pass-controlled Black labour.
- When did British rule of South Africa end?
- The Union of South Africa became self-governing in 1910, left the Commonwealth and declared itself a republic in 1961. Neither date ended colonial rule for the majority: the 1913 Natives Land Act and the apartheid legislation of 1948 onwards kept the colonial land and labour order in place until the first non-racial elections in April 1994.
