The National Flag of Angola came into use at independence on November 11, 1975. It is split horizontally into an upper red half and a lower black half.

Like in some other African countries this flag is a modification of the ruling party's flag. The guerilla movement and later governing party, the Popular Movement for the Liberation of Angola (MPLA) used the same design with a golden star in the center. Red stood for socialism and black for Africa. The star was modeled after the red star of the Soviet Union, which sponsored the MPLA.
