Aymer de Valence, 2nd Earl of Pembroke

Aymer de Valence, 2nd Earl of Pembroke was a Franco-English nobleman. Though primarily active in England, he also had strong connections with the French royal house. One of the wealthiest and most powerful men of his age, he was a central player in the conflicts between Edward II of England and his nobility, particularly Thomas, 2nd Earl of Lancaster. Pembroke was one of the Lords Ordainers appointed to restrict the power of Edward II and his favourite Piers Gaveston. His position changed with the great insult he suffered when Gaveston, as a prisoner in his custody whom he had sworn to protect, was removed and beheaded on the instigation of Lancaster. This led Pembroke into close and lifelong cooperation with the King. Later in life, however, political circumstances combined with financial difficulties would cause him problems, driving him away from the centre of power.
