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.
National Convention (Namibia) The National Convention was an alliance of political parties in South West Africa. It was formed in 1971 when the International Court of Justice ruled that South African rule in Namibia was illegal, and it consisted of various pro-independence groups and parties, including the South West Africa National Union (SWANU), the South West Africa Peoples Organization (SWAPO) and the National Unity Democratic Organisation (NUDO) formed the National Convention as a united front against South African rule. Clemens Kapuuo was its first head.
