The Sao Tome and Principe flag was officially adopted in 1975, shortly after gaining its independence from Portugal.
The red triangle symbolizes that hard-fought struggle for independence, and the two black stars represent the country's two main islands. The green, yellow and black are the Pan-African colors.
Sao Tome Coat of Arms:
