 Heraldic emblems are symbols that represent an important individual or family. They were strictly regulated by heralds, from the College of Arms and the Court of Chivalry. The officers of arms were responsible for studying coats of arms and heraldic badges, ruling on questions of rank, and granting new arms. A coat of arms was used exclusively by the individual to whom it belonged. Heraldic badges were worn or carried by servants, followers, retainers and other people wishing to show their allegiance to a particular person or family. They would also be attached or embroidered on standards, banners, uniforms, horse trappings and other property.
