Long before the British annexed the Cape Colony, there were already large Dutch-speaking European settlements in the Cape Peninsula and beyond; by the time British rule became permanent in 1806, these had a population of over 26,000. There were, however, two distinct subgroups in the population settled under the VOC. The first were itinerant farmers who began to progressively settle further and further inland, seeking better pastures for their livestock and freedom from the VOC's regulations. This community of settlers collectively identified themselves as Boers to describe their agricultural way of life. Their farms were enormous by European standards, as the land was free and relatively underpopulated; they merely had to register them with the VOC, a process that was little more than a formality and became more irrelevant the further the Boers moved inland. A few Boers adopted a semi-nomadic lifestyle permanently and became known as . The Boers were deeply suspicious of the centralised government and increasing complexities of administration at the Cape; they constantly migrated further from the reaches of the colonial officialdom whenever it attempted to regulate their activities. By the mid-eighteenth century the Boers had penetrated almost a thousand kilometres into South Africa's interior beyond the Cape of Good Hope, at which point they encountered the Xhosa people, who were migrating southwards from the opposite direction. Competition between the two communities over resources on the frontier sparked the Xhosa Wars. Harsh Boer attitudes towards black Africans were permanently shaped by their contact with the Xhosa, which bred insecurity and fear on the frontier.
