The First Boer War (Afrikaans: Eerste Vryheidsoorlog, lit. 'First Freedom War'), also known as the Transvaal War, was fought from 16 December 1880 until 23 March 1881 between the United Kingdom and Boers of the Transvaal (as the South African Republic was known while under British administration). The war resulted in a Boer victory and eventual independence of the South African Republic. The war is also known as the First Anglo–Boer War, the Transvaal War or the Transvaal Rebellion.
In the 19th century, Britain at some times attempted to set up a single unified state in southern Africa, and at other times wanted to control less territory. The British Empire's expansion in South Africa was accelerated due to the desire to control trade routes between India via the Cape of Good Hope, the discovery of diamonds in Kimberley in 1867, and the race against other European powers to control as much of Africa as possible.
The British annexation of the Transvaal in 1877 represented one of their biggest incursions into southern Africa, but other expansions also occurred. In 1868 the United Kingdom annexed Basutoland (modern Lesotho in the Drakensberg mountains, surrounded by the Cape Colony, the Orange Free State and Natal), following an appeal from Moshoeshoe, the leader of a mixed group of mostly Sotho-speaking refugees from the Difaqane who sought British protection from both the Boers and the Zulus. In the 1880s, the Tswana country became an object of dispute between the Germans to the west, the Boers to the east, and the British in the Cape Colony to the south. Although the Tswana country had at the time almost no economic value, the "Missionaries Road" passed through it toward territory farther north. After the Germans annexed Damaraland and Namaqualand (modern Namibia) in 1884, the British annexed Bechuanaland in two parts in 1885: the Bechuanaland Protectorate (modern Botswana) and British Bechuanaland (later part of the Cape Colony).
Following the Battle of Blaauwberg (1806), Britain had formally acquired the Cape of Good Hope in South Africa from the Dutch in 1814 after the Napoleonic Wars. Certain groups of Dutch-speaking settler farmers (Boers) resented British rule, even though British control brought some economic benefits. Successive waves of migrations of Boer farmers (known as Trekboers which literally means "travelling farmers"), probed first east along the coast away from the Cape toward Natal, and thereafter north toward the interior, eventually establishing the republics that came to be known as the Orange Free State and the Transvaal (literally "across/beyond the Vaal River").
The British did not try to stop the Trekboers from moving away from the Cape. The Trekboers functioned as pioneers, opening up the interior for those who followed, and Britain gradually extended control outwards from the Cape along the coast toward the east, eventually annexing Natal in 1843.
The Trekboers were farmers, gradually extending their range and territory with no overall agenda. The formal abolition of slavery in the British Empire in 1834 led to more organised groups of Boer settlers attempting to escape British rule, some travelling as far north as modern-day Mozambique. This became known as the Great Trek, and those who took part in it are called Voortrekkers.
Indeed, the British subsequently acknowledged two new Boer Republics in a pair of treaties: the Sand River Convention of 1852 recognised the independence of the Transvaal Republic, and the Orange River Convention of 1854 recognised the independence of the Orange Free State. However, British colonial expansion, from the 1830s, featured skirmishes and wars against both Boers and native African tribes for most of the remainder of the century.
The discovery of diamonds in 1867 near the Vaal River, some 550 miles (890 km) northeast of Cape Town, ended the isolation of the Boers in the interior and changed South African history. The discovery triggered a diamond rush that attracted people from all over the world, turning Kimberley into a town of 50,000 within five years and drawing the attention of British imperial interests. In the 1870s the British annexed Griqualand West, site of the Kimberley diamond discoveries.
In 1875 Henry Herbert, 4th Earl of Carnarvon, the British Secretary of State for the Colonies, in an attempt to extend British influence, approached the Orange Free State and the Transvaal Republic and tried to organise a federation of the British and Boer territories modelled on the 1867 federation of the French and English speaking provinces of Canada. However the cultural and historical context differed entirely, and the Boer leaders turned him down. Successive British annexations, and in particular the annexation of West Griqualand, caused a climate of simmering unease in the Boer republics. The president of the Transvaal Republic from 1872 to 1877 was T. F. Burgers. The Transvaal Republic was in serious financial trouble because of problems with tax collection and a war with the Pedi under the leadership of Sekhukhune in the North-East Transvaal. In 1877, the British annexed the Transvaal, which was bankrupt, and under threat from the Zulu.
Sir Theophilus Shepstone was sent by Lord Carnarvon as a special commissioner to the Transvaal. Shepstone did not initially disclose his true intentions to the Transvaal government, but at the end of January 1877 Shepstone admitted to Burgers that Britain was going to annex the Transvaal Republic. Burgers' response was to convince the Transvaal government to act in a more serious manner, but the Transvaal government refused to see the urgency of their predicament. Lord Carnarvon thought that the annexation of the Transvaal would be the first step in creating a confederation under British authority.
On 12 April 1877, a proclamation of the annexation of the Transvaal Republic was made in Church Square, Pretoria, the capital city of the Transvaal. The Transvaal Republic was now known as the British Colony of the Transvaal. A Transvaal government delegation comprising Paul Kruger and E. J. P. Jorrisen went to London in 1877 to present their case on behalf of the Transvaal to Lord Carnarvon, but their efforts were unsuccessful. The Transvaal Volksraad (People's Council) asked Transvaal citizens not to commit acts of violence, as this would create a negative image of the Transvaal in Britain. In April 1880, the Liberal Party was elected as the new government in Britain, and the feeling in the Transvaal was that this would lead to the return of sovereignty to the Transvaal. However, the new British prime minister, W.E. Gladstone, reiterated British control. In October 1880, a newspaper from Paarl in the Cape Colony reported: "Passive resistance is now becoming futile".
With the defeat of the Zulus, and the Pedi, the Transvaal Boers were able to give voice to the growing resentment against the 1877 British annexation of the Transvaal and complained that it had been a violation of the Sand River Convention of 1852, and the Bloemfontein Convention of 1854.
Major-General Sir George Pomeroy Colley, after returning briefly to India, finally took over as Governor of Natal, Transvaal and Military Commander in July 1880. Multiple commitments prevented Colley from visiting the Transvaal where he knew many of the senior Boers. Instead he relied on reports from the Administrator, Sir Owen Lanyon, who had no understanding of the Boer mood or capability. Belatedly Lanyon asked for troop reinforcements in December 1880 but was overtaken by events.
The Boers revolted on 16 December 1880 and took action at Bronkhorstspruit against a British column of the 94th Foot who were returning to reinforce Pretoria.
The trigger for the war came when a Boer named Piet Bezuidenhout (see Gerhardminnebron) refused to pay an illegally inflated tax. Government officials seized his wagon and attempted to auction it off to pay the tax on 11 November 1880, but a hundred armed Boers disrupted the auction, assaulted the presiding sheriff, and reclaimed the wagon. The first shots of the war were fired when this group fought back against government troops who were sent after them.
