Answer 1

The purpose of the English coat of arms imagery of the 1100s was primarily to self-identify when in battle. Heraldry, including coats of arms, originated as a way for knights and nobles to distinguish themselves in the chaos of battle and tournaments. The distinct designs and symbols allowed warriors to identify allies and enemies, as well as to convey lineage and status. While coats of arms could also serve other functions, such as identifying property or asserting claims, their primary role during the medieval period was identification in combat.
