Robert Fitzwalter - 12th Century Wax Seal Stamp – Magna Carta Baron and “Marshal of the Army of God and Holy Church”

(Robert Fitzwalter, Fitz Walter, Robertus filius Walteri, feudal baron of Little Dunmow)

This wax seal stamp is based on the heraldic arms associated with Robert Fitzwalter (c. 1162–1235), one of the most powerful and outspoken barons in medieval England, remembered above all as a principal leader of the rebellion against King John and a key architect behind the Magna Carta of 1215.

Fitzwalter, holder of the feudal barony of Little Dunmow in Essex, was a veteran of the Third Crusade and a politically formidable figure during the turbulent reign of King John. As tensions between the crown and the nobility escalated, Fitzwalter emerged as the de facto military leader of the rebel barons. Styling himself as the “Marshal of the Army of God and Holy Church,” he led armed opposition against the king’s abuses of power.

After compelling King John to seal the Magna Carta at Runnymede in June 1215, Fitzwalter's legacy was cemented as a defender of liberty and justice. Though conflict continued after the charter’s sealing, his name would live on as one of the twenty-five barons chosen to enforce the Magna Carta—a symbol of constitutional resistance and the birth of legal rights in England.

This wax seal features a historically accurate heraldic design based on Fitzwalter’s arms: Or, a fess gules between two chevrons of the last, evoking his noble lineage and role in defending baronial rights.

Perfect for collectors of medieval history, enthusiasts of English legal heritage, and admirers of the barons who stood up to tyranny, this seal is a tribute to one of England’s original guardians of liberty.
