What is black red and yellow flag?

The black, red, and yellow flag is the flag of the Pan-African movement and symbolizes the unity of all African peoples. The colors were chosen for their significance: black represents the people, red represents the blood of those who fought for liberation, and yellow represents the wealth of Africa's resources. The flag was first used in 1920 at the Universal Negro Improvement Association's convention in New York City and has since become a symbol of solidarity and pride for people of African descent worldwide.
