Within three years, almost half of these 1820 Settlers had retreated to the towns, notably Grahamstown and Port Elizabeth, to pursue the jobs they had held in Britain.
While doing nothing to resolve the border dispute, this influx of settlers solidified the British presence in the area, thus fracturing the relative unity of white South Africa.
A pattern soon emerged whereby English-speakers became highly urbanised, and dominated politics, trade, finance, mining, and manufacturing, while the largely uneducated Boers remained on their farms.
Yet the British settlers' conservatism and sense of racial superiority stopped any radical social reforms, and in 1841 the authorities passed a Masters and Servants Ordinance, which perpetuated white control.
In the early 19th century, Nguni tribes in KwaZulu-Natal began to shift from a loosely organised collection of kingdoms into a centralised, militaristic state.
Dingaan also attempted to establish relations with the British traders on the Natal coast, but events had started to unfold that would see the demise of Zulu independence.
[1] Beginning in 1835, several groups of Boers, together with large numbers of Khoikhoi and black servants, decided to trek off into the interior in search of greater independence.
North and east of the Orange River (which formed the Cape Colony's frontier) these Boers or Voortrekkers ("Pioneers") found vast tracts of apparently uninhabited grazing lands.
Little did they know that what they found – deserted pasture lands, disorganised bands of refugees, and tales of brutality – resulted from the difaqane, rather than representing the normal state of affairs.
However, the mountains where King Moshoeshoe I had started to forge the Basotho nation that would later become Lesotho and the wooded valleys of Zululand proved a more difficult proposition.
Here the Boers met strong resistance, and their incursions set off a series of skirmishes, squabbles, and flimsy treaties that would litter the next 50 years of increasing white domination.
The British set about establishing large sugar plantations in Natal, but found few inhabitants of the neighbouring Zulu areas willing to provide labour.
Towns sprang up in which the inhabitants ignored the "proper" separation of whites and blacks, and the Boers expressed anger that their impoverished republics had missed out on the economic benefits of the mines.
Meanwhile, the British, who viewed their defeat at Majuba as an aberration, forged ahead with their desire to federate the Southern African colonies and republics.
Johannesburg's population exploded to about 100,000 by the mid-1890s, and the ZAR suddenly found itself hosting thousands of uitlanders, both black and white, with the Boers squeezed to the sidelines.
In 1895, a group of renegades led by Captain Leander Starr Jameson entered the ZAR with the intention of sparking an uprising on the Witwatersrand and installing a British administration.
The scheme ended in fiasco, but it seemed obvious to Kruger that it had at least the tacit approval of the Cape Colony government, and that his republic faced danger.
By 1902, 26,000 Boers (mainly women and children) had died of disease, hunger and neglect in the camps, the brutal conditions documented by the British humanitarian Emily Hobhouse.
The Afrikaners found themselves in the position of poor farmers in a country where big mining ventures and foreign capital rendered them irrelevant.
The authorities imposed unpopular taxes, while the British caretaker administrator encouraged the immigration of thousands of Chinese that undercut wages.
The British High Commission territories of Basutoland (now Lesotho), Bechuanaland (now Botswana), Swaziland, and Rhodesia (now Zambia and Zimbabwe) continued under direct rule from Britain.
Despite a major campaign by Blacks and Coloureds, the voter franchise remained as in the pre-Union republics and colonies, and only whites could gain election to Parliament.
