text: History The Ovambo started migrating to their current location around the 14th century from the Zambia region to the northeast. They settled near the Angola-Namibia border then expanded further south in Namibia in the 17th century. They have a close cultural, linguistic and historical relationship to the Herero people found in more southern parts of Namibia, and Kavango people to their east settled around the Okavango River.
  In contrast to most ethnic groups in Africa, their isolated, low-density pastoral nomadic lifestyle left the Ovambo people largely unaffected by Swahili-Arab and European traders before the 19th century. When Germany established a colony in Namibia in 1884, they left the Ovambo people undisturbed. The Germans focused on the southern and coastal regions. After World War I, Namibia was annexed by the South African government into the Union of South Africa as the Territory of South West Africa. This brought major changes, with South African plantation, cattle breeding and mining operations entering the Ovamboland. The Portuguese colonial administration in Angola, who had previously focused on their coastal, northern and eastern operations, entered southern Angola to form a border with the expanding South African presence. The Ovambo people launched several armed rebellions against South African rule in the 1920s and 1930s, which were all suppressed by the Union Defence Force.
