intercede on Llywelyn's behalf. Bren was sent as a prisoner first to London in July 1316, and the Tower of London from 27 July 1316 to 17 June 1317. Hereford and Mortimer urged the King to pardon Llywelyn and his family and it seems likely that their influence won a pardon for many of Llywelyn's men. In 1317 Llywelyn became the prisoner of the ruthless Hugh, the younger Despenser, one of King Edward's favourites at court, who had become Lord of Glamorgan in November 1317 and so the largest landowner in South Wales and a great rival of Mortimer. Without the king's direction, he took Llywelyn Bren to Cardiff Castle, where he had him hanged, drawn and quartered with conspicuous judicial process. After parts of his body had been exhibited in various parts of the county he was buried in the Grey Friars at Cardiff. Llywelyn's lands were seized by Despenser. The action was condemned at the time and later used as example of the growing tyranny of Despenser, who also imprisoned Lleucu and some of her sons in Cardiff. The aftermath As antipathy to the Despensers grew, Llywelyn's death united the native Welsh and Marcher Lords. In 1321 a baronial revolt arose. Barons under the Earl of Hereford and others like Hugh D'Audley and Roger D'Amory petitioned the king to dismiss Despenser; the murder of Llywelyn Bren was prominent on their list of complaints. When the king refused, an alliance of local Welsh men and Marcher Lords raided Despenser's lands in Glamorgan for some ten days. This may have been when Lleucu and her sons were freed – certainly Hereford took all Llywelyn's sons into his service about that time. Edward had to exile the Despensers until he gathered forces to defeat the barons at the Battle of Boroughbridge in 1322, where the Earl of Hereford died. With the Despensers' return to Edward's court, Lleucu and her sons were again imprisoned, this time in Bristol Castle, but their actions soon aroused more resistance. In October 1326 a successful rebellion led by Roger Mortimer gave the Despensers and Edward further cause to regret their actions in Glamorgan after being forced to flee there. Their attempts to raise troops locally were an unsurprising failure. It led to their capture in November. Hugh, like Llywelyn, was then hanged, drawn and quartered; Edward was deposed, imprisoned, and probably murdered. With the overthrow of
