Officially adopted at independence in 1975, the national flag of Angola consists of two colors in horizontal bands, bright red on the top and black below. The red symbolizes the blood shed by Angolans during colonial oppression and its struggle for freedom, and black symbolizes the African continent. In the center is an image of a portion of a cog wheel, a machete, and a five-point star in yellow. Inspired by hammer and sickle, the cog wheel symbolizes industrial production; the machete symbolizes agriculture and armed struggle; and the star symbolizes international solidarity. Its yellow color is said to represent Angola’s mineral wealth.
