Heraldic symbols are distinctive designs used in heraldry, a system of identification that dates back to the Middle Ages. These symbols often appear on shields, banners, and coats of arms, representing families, organizations, or nations. Common elements include animals, colors, and geometric shapes, each carrying specific meanings. For example, a lion often symbolizes courage, while the color blue can represent loyalty. Each heraldic symbol follows specific rules and traditions, known as heraldic law. This ensures that designs are unique and meaningful. The study of these symbols can reveal information about a person's lineage, achievements, or social status, making them important in historical and genealogical research.
