Coat of arms — Middle Ages

The story behind the answer

This is an armorial shield displaying formalized colors (tinctures) and symbols (charges) used to identify a person, family, or institution. Such designs appeared on shields, surcoats, and seals and were described in a precise heraldic language called blazon. Unlike a “family crest” (which is only the device above the helmet), a badge (a simpler emblem worn by followers), or a royal standard (a flag), this full shield design represents the bearer’s official heraldic identity.

Heraldry blossomed in the 12th century when closed helmets hid faces on the battlefield, making visual identification crucial. Over time, these bearings became hereditary and strictly regulated by heralds. Many include additional elements—helm, crest, motto, and supporters—and their symbols could signal lineage, alliances, achievements, or territorial claims.
