Northern Cape has the country that gained independence from what nation in 1990 on its northwest border?
Northern Cape The Northern Cape (Afrikaans: "Noord-Kaap" ; Tswana: "Kapa Bokone" ) is the largest and most sparsely populated province of South Africa. It was created in 1994 when the Cape Province was split up. Its capital is Kimberley. It includes the Kalahari Gemsbok National Park, part of the Kgalagadi Transfrontier Park, an international park shared with Botswana. It also includes the Augrabies Falls and the diamond mining regions in Kimberley and Alexander Bay. The Namaqualand region in the west is famous for its Namaqualand daisies. The southern towns of De Aar and Colesberg, in the Great Karoo, are major transport nodes between Johannesburg, Cape Town and Port Elizabeth. In the northeast, Kuruman is known as a mission station and also for its artesian spring, the Eye of Kuruman. The Orange River flows through the province, forming the borders with the Free State in the southeast and with Namibia to the northwest. The river is also used to irrigate the many vineyards in the arid region near Upington.
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.
