The Battle of Monmouth took place on 25 November 1233, the feast day of St Catherine, between forces loyal to Henry III, King of England, and those of Richard Marshal, Earl of Pembroke and Lord Marshal of England, who had formed an alliance with the Welsh prince Llywelyn ap Iorwerth and his supporter Owain ap Gruffydd, a grandson of Rhys of Deheubarth.
