The national flag of Angola is split horizontally into an upper red half and a lower black half. The red is for the blood spilt by Angolans during their independence struggles, while the black is for the continent of Africa. The symbol in the middle is of a crossed cog wheel and machete with a star, that are supposed to represent the workers. It is also supposed to be similar to the hammer and sickle found on the flag of the former Soviet Union and a symbol of Communism.
