Notable German coats of arms or heraldry have been used since ancient times and are still in use today. The most notable are likely the coats of arms that represent German federal states and historic historical coats of arms, such as the Coat of Arms of Saxony, The Arms of the Holy Roman Empire and The Great Arms of the German Empire.
Coats of arms have certain heraldic rules to represent their symbolism and generally include aspects of the crest, wreath, mantle, helmet, supporters, shield of the arms, compartment and motto. A coat of arms is designed to distinguish oneself through a symbol representing family, lineage, country, kingdom or corporations. Many coat of arm designs and their meanings for notable, historic and modern German coats of arms can be found online from websites like Archives.
