Heraldry (/ˈhɛrəldri/) is a broad term, encompassing the design, display, and study of armorial bearings (known as armory), as well as related disciplines, such as vexillology, together with the study of ceremony, rank, and pedigree.[1][2][3] Armory, the best-known branch of heraldry, concerns the design and transmission of the heraldic achievement, more commonly known as the coat of arms. The coat of arms usually includes a shield, helmet, and crest, together with any accompanying devices, such as supporters, badges, heraldic banners, and mottoes
