A coat of arms is a HERALDIC design that is used to identify a family, organization, or individual. It typically consists of a shield with symbols and colors that represent the family's history and values. HERALDIC designs are often used on flags, banners, and other forms of insignia. The term 'HERALDIC' comes from the Latin word 'heraldus, ' which means 'MESSENGER.' Heraldry is an ancient practice that dates back to the Middle Ages, when knights and noble families used coats of arms to distinguish themselves from one another.
