Bushmen (or San) are generally assumed to have been the earliest inhabitants of the region. Later inhabitants include the Nama and the Damara or Berg Dama. The Bantu-speaking Ovambo and Herero migrated from the north in about the 14th century A.D.

Also in 1966, the South West Africa People's Organization (SWAPO) began guerrilla attacks on Namibia, infiltrating the territory from bases in Zambia. After Angola became independent in 1975, SWAPO accomplished bases in the southern part of the nation. Hostilities intensified over the years, particularly in Ovamboland. In a 1971 advisory opinion, the International Court of Justice upheld UN authority over Namibia, determining that the South African presence in Namibia was illegal and that South Africa therefore was obligated to withdraw its administration from Namibia immediately. The Court also advised UN member states to refrain from implying legal recognition or assistance to the South African presence.
