He rebelled against King Edward II and the Despencers. His epithet, and that of each previous and subsequent head of his family, was coined by John Smyth of Nibley (died 1641), steward of the Berkeley estates, the biographer of the family and author of Lives of the Berkeleys.

He succeeded his father in 1321, but within a few months joined Thomas, 2nd Earl of Lancaster, in his rebellion against the king. He surrendered in February 1322 and the king confiscated his estate. He spent the remainder of his life as a prisoner in Wallingford Castle (now in Oxfordshire, previously in Berkshire).

Marriages and children He married: Eve de la Zouche (d. 1314), daughter of Eudo Zouche and his wife, Millicent Cantilupe, daughter and eventual co-heiress of William III Cantilupe in 1289, when they were both children. He married Margaret de Vere, who was probably the sister of John de Vere, 7th Earl of Oxford. Millicent Berkeley, who married John Maltravers, 1st Baron Maltravers.

Isabel Clare (d. c. 1338), daughter of Gilbert Clare, 6th Earl of Hertford, about 1317.
