King of Wales

Owain Gwynedd (in English, "Owen") (c. 1100–November 28, 1170), alternatively known by the patronymic "Owain ap Gruffydd". He is occasionally referred to as Owain I of Gwynedd, or Owain I of Wales on account of his claim to be King of Wales. He is considered to be the most successful of all the north Welsh princes prior to his grandson, Llywelyn the Great. He was known as Owain Gwynedd to distinguish him from another contemporary Owain ap Gruffydd, ruler of part of Powys who was known as Owain Cyfeiliog. Owain Gwynedd was a member of the House of Aberffraw, a descendant of the senior branch from Rhodri Mawr.

Early life

Owain's father, Gruffydd ap Cynan, was a strong and long-lived ruler who had made the principality of Gwynedd the most influential in Wales during the sixty-two years of his reign, using the island of Anglesey as his power base. His mother, Angharad ferch Owain, was the daughter of Owain ab Edwin. Owain was the second of three sons of Gruffydd and Angharad.

Owain is thought to have been born on Anglesey about the year 1100. By about 1120 Gruffydd had grown too old to lead his forces in battle and Owain and his brothers Cadwallon and later Cadwaladr led the forces of Gwynedd against the Normans and against other Welsh princes with great success. His elder brother Cadwallon was killed in a battle against the forces of Powys in 1132, leaving Owain as his father's heir. Owain and Cadwaladr, in alliance with Gruffydd ap Rhys of Deheubarth, won a major victory over the Normans at Crug Mawr near Cardigan in 1136 and annexed Ceredigion to their father's realm.

Accession to the throne and early campaigns

On Gruffydd's death in 1137, therefore, Owain inherited a portion of a well-established kingdom, but had to share it with Cadwaladr. In 1143 Cadwaladr was implicated in the murder of Anarawd ap Gruffydd of Deheubarth, and Owain responded by sending his son Hywel ab Owain Gwynedd to strip him of his lands in the north of Ceredigion. Though Owain was later reconciled with Cadwaladr, from 1143, Owain ruled alone over most of north Wales. In 1155 Cadwaladr was driven into exile.

Owain took advantage of the civil war in England between King Stephen and the Empress Matilda to push Gwynedd's boundaries further east than ever before. In 1146 he captured the castle of Mold and about 1150 captured Rhuddlan and encroached on the borders of Powys. The prince of Powys, Madog ap Maredudd, with assistance from Earl Ranulf of Chester, gave battle at Coleshill, but Owain was victorious.

War with King Henry II

All went well until the accession of King Henry II of England in 1154. Henry invaded Gwynedd in 1157 with the support of Madog ap Maredudd of Powys and Owain's brother Cadwaladr. The invasion met with mixed fortunes. King Henry was nearly killed in a skirmish near Basingwerk and the fleet accompanying the invasion made a landing on Anglesey where it was defeated. Owain was however forced to come to terms with Henry, being obliged to surrender Rhuddlan and other conquests in the east.

Madog ap Maredudd died in 1160, enabling Owain to regain territory in the east. In 1163 he formed an alliance with Rhys ap Gruffydd of Deheubarth to challenge English rule. King Henry again invaded Gwynedd in 1165, but instead of taking the usual route along the northern coastal plain, the king's army invaded from Oswestry and took a route over the Berwyn hills. The invasion was met by an alliance of all the Welsh princes, with Owain as the undisputed leader. However there was little fighting, for the Welsh weather came to Owain's assistance as torrential rain forced Henry to retreat in disorder. The infuriated Henry mutilated a number of Welsh hostages, including two of Owain's sons.

Henry did not invade Gwynedd again and Owain was able to regain his eastern conquests, recapturing Rhuddlan castle in 1167 after a siege of three months.
