Nama from South Africa, who already possessed some firearms, entered the land and were followed, in turn, by white merchants and German missionaries. At first, the Nama began displacing the Herero, leading to bitter warfare between the two groups, which lasted the greater part of the 19th century. Later the two peoples entered into a period of cultural exchange. German South West Africa During the late 18th century, the first Europeans began entering to permanently settle the land. Primarily in Damaraland, German settlers acquired land from the Herero in order to establish farms. In 1883, the merchant Franz Adolf Eduard Lüderitz entered into a contract with the native elders. The exchange later became the basis of German colonial rule. The territory became a German colony under the name of German South West Africa. Soon after, conflicts between the German colonists and the Herero herdsmen began. Controversies frequently arose because of disputes about access to land and water, but also the legal discrimination against the native population by the white immigrants. In the late 19th and early 20th century, imperialism and colonialism in Africa peaked, affecting especially the Hereros and the Namas. European powers were seeking trade routes and railways, as well as more colonies. Germany officially claimed their stake in a South African colony in 1884, calling it German South West Africa until it was taken over in 1915. The first German colonists arrived in 1892, and conflict with the indigenous Herero and Nama people began. As in many cases of colonization, the indigenous people were not treated fairly. Between 1893 and 1903, the Herero and Nama people's land and cattle were progressively being taken by German colonists. The Herero and Nama resisted expropriation over the years, but they were unorganized and the Germans defeated them with ease. In 1903, the Herero people learnt that they were to be placed in reservations, leaving more room for colonists to own land and prosper. In 1904, the Herero and Nama began a great rebellion that lasted until 1907, ending with the near destruction of the Herero people. "The war against the Herero and Nama was the first in which German imperialism resorted to methods of genocide...." Roughly 80,000 Herero lived in German South West Africa at the beginning of Germany's colonial rule over the area, while after their revolt was defeated, they numbered approximately 15,000. In a period of four years, approximately
