British heraldry is a system of symbols and designs used to identify individuals, families, and institutions, particularly in the context of nobility. It originated in the Middle Ages when knights needed a way to distinguish themselves in battle. Heraldic symbols, known as coats of arms, often include animals, colors, and patterns that represent the values and history of the bearer. Each coat of arms is unique and follows specific rules, known as heraldic law. These designs are often displayed on shields, banners, and official documents. The College of Arms in London is responsible for regulating heraldry in England, ensuring that each coat of arms is properly registered and used.
