Other forms: heraldries
Heraldry is the study of designs on coats of arms — the official symbols or emblems of royal and noble families — which have appeared on flags and shields throughout history.
Heraldry is the art of designing emblems that are meant to represent families, states, or organizations, as well as the study of the significance behind the designs, including family genealogies. The original function of heraldry was to distinguish troops from each other, making it clear who soldiers were fighting with and against. The ancient root of the word heraldry means "war."
