Web Notes notes for Owain Fawr AP GRUFFYDD Prince Of Gwynedd
Weis' "Ancestral Roots. . ." (176:5), (239:6). Bartrum's "Welsh Genealogies".
Often referred to as Owain Gwynedd or as Owain Fawr (The Great). In 1136, Owain and his brothers wrested control of Ceridigion from RICHARD DE CLARE. In 1137, upon the death of his father, he became king of Gwynedd. The years of the Reign of King Stephen in England (1135-1154) were sometimes referred to as "the anarchy". Owain took advantage of these years to greatly expand the kingdom of Gwynedd until it reached almost to the town of Chester. The very capable King HENRY II ascended the English throne in in 1154. This ended the anarchy and HENRY directed many of his vast resources towards subjugating Wales.
In 1156, the ruler of Powys, MADOG AP MAREDUDD, found it necessary to yield to HENRY and in 1157 assisted him in his campaigns against Owain. This was partly due to the fact that Owain had territorial ambitions in parts of Powys. After the campaign of 1157 Owain also yielded to HENRY, acknowledging him as his sovereign.
In 1165 Owain succeeded in forming an alliance with the others Welsh rulers, RHYS AP GRUFFUDD of Dheubarth and the rulers of Powys. HENRY was, for several years beginning in 1163, hampered greatly in everything he did due to his conflict with Thomas Becket, the Archbishop of Canterbury. This, along with a victory over HENRY's troops in 1165 in the Berwyn Mountains, allowed the Welsh to regain much of the territory they had lost to the Normans. In 1168 Owain even offered to assist King LOUIS VII against Henry - an indication that he
aspired to total sovereignty for his people. Unfortunately, when Owain died in 1170, a struggle for succession followed.

Prince of Gwynedd from 1137 until his death in 1170, took advantage of the troubled reign of King Stephen of England and seized some neighboring territories. In 1157, Henry II led an army into Wales and Owain acknowledged Henry II as overlord. Owain kept all the territory he had gained with the exception of Tegeingl in the extreme north east. Owain died on November 28, 1170 and was interred at Bangor Cathedral. Owain married Gwladys, a daughter of Llywarch ap Trahaearn ap Cardogog whose father Trahaearn ap Cardogog had been killed in 1081 by Owain's father Gruffydd ap Cynan.

From Wikipedia:
Owain ap Gruffydd ("Owain son of Gruffydd"; c. 1100 – 28 November 1170) was King of Gwynedd in Northern Wales from 1137 until his death in 1170. He was the first to be styled "Prince of Wales". He is considered to be the most successful of all the North Welsh princes prior to his grandson, Llywelyn the Great. He became known as Owain Gwynedd (Middle Welsh: Owain Gwyned, "Owain of Gwynedd") to distinguish him from the contemporary king of southern Powys Owain ap Gruffydd ap Maredudd, who became known as "Owain Cyfeiliog". Owain Gwynedd was a member of the House of Aberffraw, the senior branch of the dynasty of Rhodri the Great. Owain ap Gruffydd ("Owain son of Gruffydd"; c. 1100 – 28 November 1170) was King of Gwynedd in Northern Wales from 1137 until his death in 1170.
He was the first to be styled "Prince of Wales.” He is considered to be the most successful of all the North Welsh princes prior to his grandson, Llywelyn the Great. He became known as Owain Gwynedd (Middle Welsh: Owain Gwyned, "Owain of Gwynedd") to distinguish him from the contemporary king of southern Powys Owain ap Gruffydd ap Maredudd, who became known as "Owain Cyfeiliog". Owain Gwynedd was a member of the House of Aberffraw, the senior branch of the dynasty of Rhodri the Great.
Owain's father, Gruffudd 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 of Tegeingl. Owain Gwynedd 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.
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.
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. Henry's forces ravaged eastern Gwynedd and destroyed many churches thus enraging the local population. The two armies met at Ewloe. Owain's men ambushed the royal army in a narrow, wooded valley, routing it completely with King Henry himself narrowly avoiding capture. The fleet accompanying the invasion made a landing on Anglesey where it was defeated. Ultimately, at the end of the campaign, Owain was forced to come to terms with Henry, being obliged to surrender Rhuddlan and other conquests in the east.
Forty years after these events, the scholar, Gerald of Wales, in a rare quote from these times, wrote what Owain Gwynedd said to his troops on the eve of battle:
"My opinion, indeed, by no means agrees with yours, for we ought to rejoice at this conduct of our adversary; for, unless supported by divine assistance, we are far inferior to the English; and they, by their behavior, have made God their enemy, who is able most powerfully to avenge both himself and us. We therefore most devoutly promise God that we will henceforth pay greater reverence than ever to churches and holy places."
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, apart from a small melee at the Battle of Crogen 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.
The last years of Owain's life were spent in disputes with the Archbishop of Canterbury, Thomas Becket, over the appointment of a new Bishop of Bangor. When the see became vacant Owain had his nominee, Arthur of Bardsey, elected. The archbishop refused to accept this, so Owain had Arthur consecrated in Ireland. The dispute continued, and the see remained officially vacant until well after Owain's death. He was also put under pressure by the Archbishop and the Pope to put aside his second wife, Cristin, who was his first cousin, this relationship making the marriage invalid under church law. Despite being excommunicated for his defiance, Owain steadfastly refused to put Cristin aside. Owain died in 1170, and despite having been excommunicated was buried in Bangor Cathedral by the local clergy.
The annalist writing Brut y Tywysogion recorded his death "after innumerable victories, and unconquered from his youth". Following his death, civil war broke out between his sons. Owain was married twice, first to Gwladus ferch Llywarch ap Trahaearn, by whom he had two sons, Maelgwn ab Owain Gwynedd and Iorwerth Drwyndwn, the father of Llywelyn the Great, then to Cristin, by whom he had three sons including Dafydd ab Owain Gwynedd and Rhodri ab Owain Gwynedd. He also had a number of illegitimate sons, who by Welsh law had an equal claim on the inheritance if acknowledged by their father.
Owain had originally designated Rhun ab Owain Gwynedd as his successor. Rhun was Owain's favorite son, and his premature death in 1147 plunged his father into a deep melancholy, from which he was only roused by the news that his forces had captured Mold castle. Owain then designated Hywel ab Owain Gwynedd as his successor, but after his death Hywel was first driven to seek refuge in Ireland by Cristina's sons, Dafydd and Rhodri, then killed at the battle of Pentraeth when he returned with an Irish army. Dafydd and Rhodri split Gwynedd between them, but a generation passed before Gwynedd was restored to its former glory under Owain's grandson Llywelyn the Great.
Altogether, the prolific Owain Gwynedd is said to have had the following children from two wives and at least four mistresses:
• Rhun ab Owain Gwynedd (illegitimate in Catholic custom, but legitimate successor in Welsh law)
• Hywel ab Owain Gwynedd (illegitimate in Catholic custom, but legitimate successor in Welsh law)
• Iorwerth ab Owain Gwynedd (from first wife Gwladys (Gladys) ferch Llywarch)
• Maelgwn ab Owain Gwynedd,(from first wife Gwladys (Gladys) ferch Llywarch) Lord of Môn (1170–1173)
