The tabard, a sleeveless coat featuring a square collar, was traditionally worn by nobles to display coats of arms. Charles Henry Ashdown outlines its development in armor during the "Tabard Period," while John Camden Hotten documents its function as a heraldic emblem.
The 1911 Encyclopædia Britannica mentions its use in 15th-century plate armor, underscoring its practicality. Although some writers, such as Caroline Bancroft, mention "Tabor" as a location or name, the tabard's influence persists in heraldic customs, connecting military function with symbolic identity through its versatile design and cultural significance.
