From the late 18th century onward, Oorlam people from Cape Colony crossed the Orange River and moved into the area that today is southern Namibia. Their encounters with the nomadic Nama tribes were largely peaceful. They received the missionaries accompanying the Oorlam very well, granting them the right to use waterholes and grazing against an annual payment. On their way further north, however, the Oorlam encountered clans of the OvaHerero at Windhoek, Gobabis, and Okahandja, who resisted their encroachment. The Nama-Herero War broke out in 1880, with hostilities ebbing only after the German Empire deployed troops to the contested places and cemented the status quo among the Nama, Oorlam, and Herero.
