Namibia ( , ), officially the Republic of Namibia, is a country in Southern Africa. Its western border is the Atlantic Ocean. It shares land borders with Zambia and Angola to the north, Botswana to the east and South Africa to the south and east. Although it does not border Zimbabwe, less than 200 metres (660 feet) of the Botswanan right bank of the Zambezi River separates the two countries. Its capital and largest city is Windhoek. The driest country in sub-Saharan Africa, Namibia has been inhabited since pre-historic times by the San, Damara and Nama people. Around the 14th century, immigrating Bantu peoples arrived as part of the Bantu expansion. Since then, the Bantu groups, the largest being the Ovambo, have dominated the population of the country; since the late 19th century, they have constituted a majority. With a population of an estimated 2.77 million people today, Namibia is one of the most sparsely populated countries in the world. In 1884, the German Empire established rule over most of the territory, forming a colony known as German South West Africa. Between 1904 and 1908, German troops waged a punitive campaign against the Herero and Nama which escalated into the first genocide of the 20th century. German rule ended during the First World War with a 1915 defeat by South African forces. In 1920, after the end of the war, the League of Nations mandated administration of the colony to South Africa. From 1948, with the National Party elected to power, this included South Africa applying apartheid to what was then known as South West Africa. In the later 20th century, uprisings and demands for political representation by native African political activists seeking independence resulted in the United Nations assuming direct responsibility over the territory in 1966, but the country of South Africa maintained de facto rule. In 1973, the UN recognized the South West Africa People's Organization (SWAPO) as the official representative of the Namibian people. Namibia gained independence from South Africa on 21 March 1990, following the Namibian War of Independence. However, Walvis Bay and the Penguin Islands remained under South African control until 1994. Namibia is a stable parliamentary democracy. Agriculture, tourism and the mining industry – including mining for gem diamonds, uranium, gold, silver and base metals – form the basis of its economy, while the manufacturing sector is comparatively small. Namibia is a member state of the United Nations, the Southern African Development Community, the African Union and the Commonwealth of Nations. Source: Wikipedia (en)
