Arms of Sir William Herbert, 1st Baron Herbert, at the time of his installation in the Most Noble Order of the Garter:Per pale azure and gules, three lions rampant argent
Soon after the decisive Yorkist victory at theBattle of Towton in 1461, Herbert replacedJasper Tudor asEarl of Pembroke which gave him control ofPembroke Castle – and with it, he gained the wardship of youngHenry Tudor. However, he fell out withLord Warwick "the Kingmaker" in 1469, when Warwick turned against the King. Herbert was denounced by Warwick and theDuke of Clarence as one of the king's "evil advisers".[2] William and his brotherRichard were executed by Warwick in Northampton, after theBattle of Edgcote, which took place in South Northamptonshire, near Banbury.[3]
Herbert was succeeded by his son,William, but the earldom was surrendered in 1479. It was later revived for a grandson,another William Herbert, the son of Black William's illegitimate son,Sir Richard Herbert ofEwyas.
