Northern Cape has the country that gained independence from what nation in 1990 on its northwest border?
Namibia Namibia ( , ), officially the Republic of Namibia (German:    ; Afrikaans: "Republiek van Namibië" ) is a country in southern Africa whose 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, a part of less than 200 metres of the Zambezi River (essentially a small bulge in Botswana to achieve a Botswana/Zambia micro-border) separates the two countries. Namibia gained independence from South Africa on 21 March 1990, following the Namibian War of Independence. Its capital and largest city is Windhoek, and it is a member state of the United Nations (UN), the Southern African Development Community (SADC), the African Union (AU), and the Commonwealth of Nations.
Boer Republics The Boer Republics (sometimes also referred to as Boer states) were fiercely independent, Protestant, self-governed republics created by the Dutch-speaking inhabitants of the Cape Colony and their descendants, variously named Trekboers, Boers and Voortrekkers in mainly the middle, northern and north eastern and eastern parts of what is now the country of South Africa. Two of the Boer Republics achieved international recognition and complete independence: the South African Republic (ZAR or Transvaal) and the Orange Free State. The republics came to an end after the Second Boer War which resulted in the British annexation and later incorporation into the Union of South Africa.
