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.
