Llywelyn AP IORWERTH The Great

(1173 - 11 Apr 1240)

During Llywelyn's boyhood, Gwynedd was ruled by two of his uncles, who split the kingdom between them, following the death of Llywelyn's grandfather, Owain Gwynedd, in 1170. Llywelyn had a strong claim to be the legitimate ruler and began a campaign to win power at an early age. He was sole ruler of Gwynedd by 1200 and made a treaty with King John of England that year. Llywelyn's relations with John remained good for the next ten years. He married John's natural daughter Joan in 1205, and when John arrested Gwenwynwyn ab Owain of Powys in 1208, Llywelyn took the opportunity to annex southern Powys. In 1210, relations deteriorated, and John invaded Gwynedd in 1211.
