A coat of arms is a unique heraldic design on a shield or escutcheon or on a surcoat or tabard used to cover and protect armor. It symbolizes the identity of an individual, family, or organization, often featuring specific colors, symbols, and patterns that represent their history, values, or achievements. Coats of arms are often used in official documents, ceremonies, and on flags. Each coat of arms is governed by specific rules of heraldry, which dictate how elements like animals, plants, and colors can be combined. For example, a lion might symbolize bravery, while a tree could represent growth. Many countries, such as England and Scotland, have their own distinct coats of arms that reflect their national identity.
