B. c.1208, s. of Llywelyn ab Iorwerth; acc. 11 Apr. 1240; m. Isabella, da. of William de Braose V; d. 25 Feb. 1246; bur. Aberconwy.

The only legitimate son of Llywelyn the Great, Dafydd was intended by his father to inherit all his territories. The succession was guaranteed by Henry III (1220), the pope (1222) and the Welsh nobility (1226, 1238), but there was tension with Dafydd's elder brother, Gruffydd, who was illegitimate. On Llywelyn's death in 1240, Henry III decided to cut down Dafydd's power and used Gruffydd against him. When Dafydd made a bid for his father's position, styling himself ‘prince of Wales’, Henry led a campaign against him in 1245. Dafydd died early the following year.
