The symbol of this holiday is the cockade, which reflects the Hungarian flag.
A cockade is a knot of ribbons, or other circular- or oval-shaped symbol of distinctive colors that is usually worn on a hat. A cockade uses distinctive colors to show the allegiance of its wearer to some political faction, their rank, or as part of a servant’s livery. In pre-revolutionary France, the cockade of the Bourbon dynasty was all white. In the Kingdom of Great Britain a white cockade was worn by those supporting the restoration of a Jacobite monarchy, while in contrast the established Hanoverian monarchy they were trying to overthrow had one that was all black.
Nowadays wearing a cockade nationwide is characteristic only of Hungary. Hungarians pin the cockade of our national colors above our hearts every year on the 15th of March, in remembrance of the Hungarian Revolution of 1848-49.
