Great Trek (1836-1840)
The British government did not approve of the actions of Sir Benjamin d'Urban, and the British Secretary for the Colonies, Lord Glenelg, declared in a letter to the King that "the great evil of the Cape Colony consists in its magnitude" and demanded that the boundary be moved back to the Fish River. He also eventually had d'Urban dismissed from office in 1837. "The Kaffirs," in Lord Glenelg's dispatch of 26 December, "had an ample justification for war; they had to resent, and endeavoured justly, though impotently, to avenge a series of encroachments.” This attitude towards the Xhosa was one of the many reasons given by the Voortrekkers for leaving the Cape Colony. The Great Trek, as it is called, lasted from 1836 to 1840. The trekkers (Boers), numbering around 7,000, founded communities with a republican form of government beyond the Orange and Vaal rivers, and in Natal, where they had been preceded, however, by British emigrants. From this time on, Cape Colony ceased to be the only European community in South Africa, though it was the most predominant for many years.
Considerable trouble was caused by the emigrant Boers on either side of the Orange River, where the Boers, the Basothos, other native tribes, Bushmen, and Griquas fought for superiority, while the Cape government endeavoured to protect the rights of the native Africans. On the advice of the missionaries, who exercised great influence on all non-Dutch people, a number of the "native states" were recognised and subsidised by the Cape government with the objective of creating peace on the northern frontier. The first "Treaty States" to be recognised was Griqualand West of the Griqua people. Subsequent states were recognised between 1843 and 1844. While the northern frontier became more secure, the state of the eastern frontier was deplorable, with the government either unable or unwilling to settle disputes between Xhosa and Cape farmers.
Elsewhere, however, the colony was making progress. The change from slave to free labour proved to be advantageous to the farmers in the western provinces. An efficient education system, owing its inception to Sir John Herschel, an astronomer who lived in Cape Colony from 1834 to 1838, was adopted. Road Boards were established and proved to be very effective in constructing new roads. A new stable industry, sheepraising, was added to the original set of wheatgrowing, cattle rearing, and wine making. By 1846, wool became the country's most valuable export. A legislative council was established in 1835, giving the colonists a share in the government.
