Missing some of the more obscure bits, but here it is!

Basic information: The Union of South Africa. The most prominent languages are English and a variant of Dutch peculiar to South Africa called Afrikaans. Someone from South Africa is a South African, but more likely they would refer to themselves by their ethnic names, such as Xhosa or Afrikaner.

History: Originally a Dutch colony, South Africa was transferred to the English around the turn of the 19th century. Many Dutch speaking Afrikaners fled to the northeast part of the country. In the course of two Boer wars, the states founded by these Dutch Afrikaans were conquered and incorporated into the British Cape Colony. Eventually South Africa gained independence and present day, Apartheid is fairly new in that country.

Politics and Government: Parliamentary Westminster style. There are two dominant parties. The National Party, advocating Apartheid, and the Union party, favoring gradual integration and expanded rights for Coloureds. It is upon race that politics turns.

Military: The South African army is the strongest in the region, as is its navy. Combined with its economic dominance, South Africa is the regional hegemon. 

Geography: Mostly desert in the interior, more lush towards the coast and Namibia.

Economy: Revolves mostly around natural resources and mining.

Culture: South Africa will decide that in a few months. South Africans will decide whether they prefer the new regime of Apartheid or to accept the tides of history and racial integration with the Union Party.
