Through England

During Llywelyn's childhood, 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 began a campaign to win power at an early age, battling his uncles Rhodri and Dafydd ab Owain Gwynedd. Rhodri died in 1195, and Gruffudd and Maredudd ap Cynan took over his lands in Gwynedd Uwch Conwy. Dafydd ab Owain was captured by Llywelyn in 1197 and subsequently exiled to England. Llywelyn secured his grip on the throne of Gwynedd when he drove his cousins Gruffudd and Maredudd ap Cynan from Gwynedd Uwch Conwy in the wake of a battle in Arfon on Epiphany 1199. He then made a treaty with King John in 1200. 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 of Powys in 1208, Llywelyn took the opportunity to annex southern Powys. In 1210, relations deteriorated, and John invaded Gwynedd in 1211. Llywelyn was forced to seek terms and to give up all lands east of the River Conwy but was able to recover them the following year in alliance with the other Welsh princes. He allied himself with the barons who forced John to sign the Magna Carta in 1215. By 1216, he was the dominant power in Wales, holding a council at Aberdyfi that year to apportion lands to the other princes.

Following King John's death, Llywelyn concluded the Treaty of Worcester with his successor, Henry III, in 1218. During the next fifteen years, Llywelyn was frequently involved in fights with Marcher lords and sometimes with the king, but also made alliances with several major powers in the Marches. The Peace of Middle in 1234 marked the end of Llywelyn's military career, as the agreed truce of two years was extended year by year for the remainder of his reign. He maintained his position in Wales until his death in 1240 and was succeeded by his son Dafydd ap Llywelyn.

Early life

Llywelyn's birth year is given as 1173 in O Oes Gwrtheyrn, a chronicle likely compiled at Aberconwy Abbey, which states "From the death of Owain until the birth of Llywelyn ab Iorwerth, two and a half years." He was probably born at Dolwyddelan the royal manor of Nantconwy, though not in the present Dolwyddelan Castle, which was built by Llywelyn himself. He may have been born in the old castle which occupied a rocky knoll on the valley floor.

Little is known about his father, Iorwerth Drwyndwn, who died when Llywelyn was an infant. There is no record of Iorwerth having taken part in the power struggle between some of Owain Gwynedd's other sons following Owain's death, although he was the eldest surviving son. There is a tradition that he was disabled or disfigured in some way that excluded him from power.

John Edward Lloyd states that Iorwerth was killed in battle at Pennant Melangell, in Powys, in 1174 during the wars deciding the succession following the death of his father.

By 1175, Gwynedd had been divided between two of Llywelyn's uncles. Dafydd ab Owain held the area east of the River Conwy and Rhodri ab Owain held the west. Dafydd and Rhodri were the sons of Owain by his second marriage to Cristin verch Goronwy. This marriage was not considered valid by the church as Cristin was Owain's first cousin, a degree of relationship which according to Canon law prohibited marriage. The chronicler Gerald of Wales refers to Iorwerth Drwyndwn as the only legitimate son of Owain Gwynedd. Following Iorwerth's death, Llywelyn was, at least in the eyes of the church, the legitimate claimant to the throne of Gwynedd.

Llywelyn's mother was Marared, occasionally anglicised to Margaret, daughter of Madog ap Maredudd, prince of Powys. There is evidence that after Iorwerth's death Marared married into the Corbet family of Caux in Shropshire, and Llywelyn may have spent part of his childhood there. There is in existence a grant of land from Llywelyn ab Iorwerth to the monastery of Wigmore, in which Llywelyn indicates his mother was a member of the house of Corbet.
