The Black Liberation flag
The red, black, and green flag that has come to be associated with black power movements was originally created as the Universal Negro Improvement Association’s standard. A wiki on the flag reports that it was created in response to a popular racist song titled “Every Nation Has a Flag But the Coon.” According to UNIA documents, the colors were chosen for the following reason:
“Red is the color of the blood which men must shed for their redemption and liberty; black is the color of the noble and distinguished race to which we belong; green is the color of the luxuriant vegetation of our Motherland.
The flag was first revealed on August 13, 1920, at the first UNIA convention. Over the past century, it has gained popularity as a symbol of pride, celebration of Black cultures, and identification with Pan-African values.
