What is a "cockade"?

A cockade is a decorative knot made of ribbon or fabric that is usually worn on a hat or headdress. Its origin dates back to the 18th century when it was worn by servants as a badge of identification. Later, it became popular among the military and was worn as a symbol of allegiance to a particular country or political faction. In some countries, it was also used as a symbol of rank or status. Cockades were often made in various colors and designs, with each color and pattern representing a specific group or cause. Today, they are still occasionally worn as decorative accessories or used as a symbol of heritage or identity.
