Angola has experienced rapid growth in the last decade, mostly propelled by the exploitation of its vast natural resources. Today, the country ranks as the third largest economy in Sub-Saharan Africa. Its history, like that of many African nations, is characterised by struggle and battle. After its independence from Portugal in 1975, Angola entered into a 27-year long civil war, where two major opposition parties, MPLA and Unita, fought for supremacy. In 2002, the two parties finally agreed on a cease-fire and started to focus on rebuilding the country. The rebirth of Angola started in 2002.
