 Born1172 / 
 Died11 April 1240 / Aberconwy Abbey
Llywelyn the Great was the supreme leader of the Welsh Lords during the reigns of both King John and King Henry III. Shortly after King John became king of England, Llywelyn signed a peace treaty ensuring good relations between England and Wales for several years and a marriage was arranged between the Welsh prince and John's illegitimate daughter Joan. At the end of King John's reign Llywelyn fought against the English when they tried to conquer Wales and sided with the barons who, in 1216, forced the King to sign the Magna Carta.

In 1218 Llywelyn signed a peace treaty at Worcester confirming the Welsh leader's ownership of lands including those he had recently captured.
