Quick Reference

(1173–1240),

prince of Gwynedd (1195–1240), known as ‘the Great’. The son of Iorwerth ‘Flatnose’ and Margaret, princess of Powys, Llywelyn spent most of his life restoring and enhancing the hegemony of his grandfather Owain Gwynedd. Good relations with King John brought recognition and his marriage to John's natural daughter Joan. But his aggression towards Powys made John retaliate (1210–11) and Llywelyn then allied with the French. He planned to perpetuate his principality by securing recognition from king and pope (1220–2) of his son Dafydd as his sole heir. He took the evocative title of prince of Aberffraw and lord of Snowdon (1230), and he compared himself to the king of Scots.
