The national flag of Angola features two equal horizontal bands of red (top) and black (bottom), with a centered yellow emblem consisting of a five-pointed star within half a cogwheel crossed by a machete (in the style of a hammer and sickle).
The red stripe represents the blood shed during Angola's struggle for independence, while the black stripe represents Africa. The yellow emblem symbolizes the country's mineral wealth, the cogwheel represents industry and the workers, the machete represents the peasants, and the star represents socialism and internationalism.
The flag was adopted on November 11, 1975, when Angola gained its independence from Portugal.
