From wikipedia about Angola
Angola, officially the Republic of
Angola (República de
Angola, ;This is the pronunciation in Portugal; in
Angola it is pronounced as it is written Kikongo, Kimbundu, Umbundu: Repubilika ya Ngola), is a country in south-central Africa bordered by
Namibia on the south, the Democratic Republic of the Congo on the north, and
Zambia on the east; its west coast is on the Atlantic Ocean with Luanda as its capital city. The exclave province of Cabinda has borders with the Republic of the Congo and the Democratic Republic of the Congo.
The Portuguese were present in some—mostly coastal—points of the territory of what is now
Angola, from the 16th to the 19th century, interacting in diverse ways with the peoples that lived there. In the 19th century they slowly and hesitantly began to establish themselves in the interior.
Angola as a Portuguese colony was not established before the end of the 19th century, and "effective occupation", as required by the Berlin Conference (1884) was achieved in the 1920s as with most African colonies. After independence,
Angola was the scene of an intense civil war from 1975 to 2002. The country has vast mineral and petroleum reserves; however, its life expectancy and infant mortality rates are both among the worst-ranked in the world. www. cia. gov (2009)
