William de Braose (c. 1197 – 2 May 1230) was the son of Reginald de Braose by his first wife, Grecia Briwere. He was an ill-fated member of the House of Braose, a powerful and long-lived dynasty of Marcher Lords.


William de Braose was born in Brecon, probably between 1197 and 1204. The Welsh, who detested him and his family name, called him Gwilym Ddu, Black William. He succeeded his father in his various lordships in 1227, including Abergavenny and Buellt.[citation needed]

William married Eva Marshal, daughter of William Marshal, 1st Earl of Pembroke. They had four daughters:[citation needed]

He was captured by the Welsh forces of Prince Llywelyn the Great, in fighting in the commote of Ceri near Montgomery, in 1228. William was ransomed for the sum of £2,000 and then furthermore made an alliance with Llywelyn, arranging to marry his daughter Isabella de Braose to Llywelyn's only legitimate son Dafydd ap Llywelyn. However, it became known that William had committed adultery with Llywelyn's wife, Joan, Lady of Wales, and Braose was taken at his own home and transported to Wales.[3] The marriage planned between their two children did, however, take place.[4]

The Chronicle of Ystrad Fflur's entry for 1230 reads:[citation needed]

"In this year William de Breos the Younger, lord of Brycheiniog, was hanged by the Lord Llywelyn in Gwynedd, after he had been caught in Llywelyn's chamber with the king of England's daughter, Llywelyn's wife".

Llywelyn had William publicly hanged on 2 May 1230,[5] possibly at Crogen, near Bala, though others believe the hanging took place near Llywelyn's palace at Abergwyngregyn.

After William's death, his wife Eva continued to hold de Braose lands and castles in her own right. She was listed as the holder of Totnes in 1230, and was granted 12 marks to strengthen Hay Castle by King Henry III on the Close Rolls (1234–1237).[citation needed]


With William's death by hanging and his having four daughters, who divided the de Braose inheritance between them and no male heir, the titles now passed to the junior branch of the de Braose dynasty, the only male heir was now John de Braose who had already inherited the titles of Gower and Bramber from his far-sighted uncle Reginald de Braose.[citation needed]
