The flag of Guinea-Bissau was adopted in 1973 when independence from Portugal was proclaimed. Like the former flag of Cape Verde, the flag is based on that of the Partido Africano para a Independencia da Guine e Cabo Verde (PAIGC), still the dominant party in Guinea-Bissau.
The flag features the traditional Pan-African colors of yellow, green, red, and also the Black Star of Africa. The flag’s design is heavily influenced by the flag of Ghana. The colors have the same meanings: specifically, the red is for the blood of martyrs, green for forests, and yellow for mineral wealth.
