Gariep
Gariep was the Khoekhoe name for the great river later called the Orange. In the country around its upper-middle course, river crossings and grazing drew together San hunters, Khoekhoe pastoralists, Xhosa groups and people moving beyond the Cape's settled districts. The river could mark a limit to colonial authority while remaining a route through a connected Indigenous interior.
By the late eighteenth century, frontier leaders such as the Xhosa chief Nzwane, known as Danster, were building followings among these mixed communities. Horses, firearms and trade strengthened mobile groups whose dealings combined negotiation, raiding and exchange. Refugees, escaped servants and people resisting colonial demands also sought room to live along the Gariep. The expansion of Cape authority increasingly narrowed that freedom. In 1824 the colony's northeastern boundary reached the river; in 1830 Colesberg was established south of it on the site of an abandoned London Missionary Society station. The new town became a base for hunters, travellers and settlers heading farther inland. River country that had long sustained African communities now stood at the edge of a rapidly expanding colonial frontier.
