divided the Clare estates. These were Hugh of Audley, who had married
Margaret the widow of Gaveston, and Roger of Amory, the husband of
Elizabeth, the youngest of the Clare sisters. There had been difficulty
enough in effecting the partition of the Gloucester inheritance among
the three co-heiresses. In 1317 the division was made, and Despenser had
become lord of Glamorgan, which politically and strategically was most
important of all the Gloucester lands.[1] Yet even then, Despenser was
not satisfied with his position. His rival Audley had been allotted
Newport and Netherwent, while Amory had been assigned the castle of Usk
and estates higher up the Usk valley. Annoyed that he should be a lesser
personage in south Wales than Earl Gilbert had been, Despenser began to
intrigue against his wife's brothers-in-law. Each of the co-heirs had
already become deadly rivals. Their hostility was the more keen since
the three had already taken different sides in English politics.
Despenser was the soul of the court faction; Amory was the ally of
Pembroke and Badlesmere, the men of the middle party; and Audley was an
uncompromising adherent of Thomas of Lancaster. There was every chance
that each one of the three would have competent backing. To each the
triumph of his friends meant the prospect of his becoming Earl of
Gloucester.

Despenser, abler and more restless than the others, and confident in
the royal favour, was the first to take the aggressive. He wished to
base his future greatness upon a compact marcher principality in south
Wales, and to that end not only laid his hands upon the outlying
possessions of the Clares but coveted the lands of all his weaker
neighbours. He took advantage of a family arrangement for the
