The symbols on the Angola flag are a machete that represents the peasants, agricultural produce and armed struggle; a partial cogwheel representing the laborers and industrial production; and a yellow star signifying international solidarity and progress. The red color of the top half symbolizes bloodshed in the country's liberation struggle, the black of the bottom half represents the African continent and yellow shows the wealth of Angola.
Angola introduced its flag on November 11, 1975 after attaining independence from Portugal. It was one of the last colonies in Africa to achieve independence. A new flag for Angola proposed in 2003 is yet to be adopted as of 2015.
The Popular Movement for the Liberation of Angola has ruled the country since its independence. President José Eduardo dos Santos has been in office since 1979 following the death of the founding president, Agostinho Neto. Angola is a major oil producer in Africa, and oil exports account for over 90 percent of its total exports. Angola is one of the main diamond producers, and its diamonds are of generally high quality. Other minerals include marble, iron ore, phosphate deposits and quartz. The country also has natural gas, fertile agricultural lands and hydroelectric potential.
