Resource : Phrygian cap

Red Phrygian or ‘liberty’ caps were long associated with the theme of liberty in European and colonial cultures. They were used as icons during the American Revolution and worn during the French Revolution in the late 1700s and came to symbolise allegiance to the republican cause. Along with the red, white and blue cockade, pinned to these and other hats, they became a lasting symbol of revolutionary France.
