Basotho
By the beginning of the South African Wars, the Orange Free State was independently ruled by the Boers. The Free State's boundaries were defined almost entirely by rivers: the Orange River on the south, the Vaal River on the west and north, and the Caledon River on the east. The northeastern boundary was shared with its British neighbour, Natal. The Caledon boundary was disputed with Moshoeshoe I's Sotho people, and fought over in two primary incidents – in 1858 and 1865. Before the Boer colonisation, there were indigenous groups like the Sotho, San, and various Nguni clans in the Free State area.
