Angola, officially the Republic of Angola, is a country in south-central Africa bordered by Namibia on the south, Democratic Republic of the Congo on the north, and Zambia on the east; its west coast is on the Atlantic Ocean. The exclave province of Cabinda has a border with the Republic of the Congo and the Democratic Republic of the Congo.
Angola was a Portuguese overseas territory from the 16th century to 1975. After independence, Angola was the scene of an intense civil war from 1975 to 2002. The country is the second-largest petroleum and diamond producer in sub-Saharan Africa; however, its life expectancy and infant mortality rates are both among the worst ranked in the world. In August 2006, a peace treaty was signed with a faction of the FLEC, a separatist guerrilla group from the Cabinda exclave in the North, which is still active. About 65% of Angola's oil comes from that region.
