Llywelyn The Last - Supremacy in Wales

Supremacy in Wales

After Simon de Montfort's death, Llywelyn launched a campaign in order to rapidly gain a bargaining position before King Henry had fully recovered. In 1265, Llywelyn captured Hawarden Castle and routed the combined armies of Hamo Lestrange and Maurice fitz Gerald in north Wales. Llywelyn then moved on to Brycheiniog, and in 1266, he routed Roger Mortimer's army. With these victories and the backing of the papal legate, Ottobuono, Llywelyn opened negotiations with the king, and was eventually recognised as Prince of Wales by King Henry in the Treaty of Montgomery in 1267. In return for the title, the retention of the lands he had conquered and the homage of almost all the native rulers of Wales, he was to pay a tribute of 25,000 marks in yearly instalments of 3,000 marks, and could if he wished, purchase the homage of the one outstanding native prince - Maredudd ap Rhys of Deheubarth - for another 5,000 marks. However, Llywelyn's territorial ambitions gradually made him unpopular with some minor Welsh leaders, particularly the princes of south Wales.

The Treaty of Montgomery marked the high point of Llywelyn's power. Problems began arising soon afterwards, initially a dispute with Gilbert de Clare concerning the allegiance of a Welsh nobleman holding lands in Glamorgan. Gilbert built Caerphilly Castle in response to this. King Henry sent a bishop to take possession of the castle while the dispute was resolved but when Gilbert regained the castle by trickery, the king was unable to do anything about it.

Following the death of King Henry in late 1272, with the new King Edward I of England away from the kingdom, the rule fell to three men. One of whom, Roger Mortimer was one of Llywelyn's rivals in the marches. When Humphrey de Bohun tried to take back Brycheiniog, which was granted to Llywelyn by the Treaty of Montgomery, Mortimer supported de Bohun. Llywelyn was also finding it difficult to raise the annual sums required under the terms of this treaty, and ceased making payments.

In early 1274, there was a plot by Llywelyn's brother, Dafydd, and Gruffydd ap Gwenwynwyn of Powys Wenwynwyn and his son, Owain, to kill Llywelyn. Dafydd was with Llywelyn at the time, and it was arranged that Owain would come with armed men on 2 February to carry out the assassination; however, he was prevented by a snowstorm. Llywelyn did not discover the full details of the plot until Owain confessed to the Bishop of Bangor. He said that the intention had been to make Dafydd prince of Gwynedd, and that Dafydd would reward Gruffydd with lands. Dafydd and Gruffydd fled to England where they were maintained by the king and carried out raids on Llywelyn's lands, increasing Llywelyn's resentment. When Edward called Llywelyn to Chester in 1275 to pay homage, Llywelyn refused to attend.

Llywelyn also made an enemy of King Edward by continuing to ally himself with the family of Simon de Montfort, even though their power was now greatly reduced. Llywelyn sought to marry Eleanor de Montfort, born in 1252, Simon de Montfort's daughter. They were married by proxy in 1275, but King Edward took exception to the marriage, in part because Eleanor was his first cousin: her mother was Eleanor of England, daughter of King John and princess of the House of Plantagenet. When Eleanor sailed from France to meet Llywelyn, Edward hired pirates to seize her ship and she was imprisoned at Windsor Castle until Llywelyn made certain concessions.

In 1276, Edward declared Llywelyn a rebel and in 1277, gathered an enormous army to march against him. Edward's intention was to disinherit Llywelyn completely and take over Gwynedd Is Conwy himself. He was considering two options for Gwynedd Uwch Conwy: either to divide it between Llywelyn's brothers, Dafydd and Owain, or to annex Anglesey and divide only the mainland between the two brothers. Edward was supported by Dafydd ap Gruffydd and Gruffydd ap Gwenwynwyn. Many of the lesser Welsh princes who had supported Llywelyn now hastened to make peace with Edward. By the summer of 1277, Edward's forces had reached the River Conwy and encamped at Deganwy, while another force had captured Anglesey and took possession of the harvest there. This deprived Llywelyn and his men of food, forcing them to seek terms.
