Gualo, Cardinal (fl. 1216), was sent to England by Pope Innocent III. in 1216. He supported John with all the weight of papal authority. After John’s death he crowned the infant Henry III. and played an active part in organizing resistance to the rebels led by Louis of France, afterwards king Louis VIII. As representing the pope, the suzerain of Henry, he claimed the regency and actually divided the chief power with William Marshal, earl of Pembroke. He proclaimed a crusade against Louis and the French, and, after the peace of Lambeth, he forced Louis to make a public and humiliating profession of penitence (1217). He punished the rebellious clergy severely, and ruled the church with an absolute hand till his departure from England in 1218. Gualo’s character has been severely criticized by English writers; but his chief offence seems to have been that of representing unpopular papal claims.
