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.
