Angola
It is a country in southwestern Africa bordering Namibia, Congo-Kinshasa, and Zambia, and with a west coast along the Atlantic Ocean. The exclave province Cabinda has a border with Congo-Brazzaville. A former Portuguese colony, it has considerable natural resources, among which oil and diamonds are the most relevant. The country is nominally a democracy and is formally named the Republic of Angola (Portuguese: República de Angola). The name Angola is a Portuguese derivation of the Bantu word N’gola, being the title of the native rulers of the region in the 16th century, at the time of colonization by the Portuguese.
