William Herbert, 1st Earl of Pembroke

William Herbert, 1st Earl of Pembroke KG ( 142327 July 1469), known as "Black William", was a Welsh nobleman, soldier, politician, and courtier.

Life He was the son of William ap Thomas, founder of Raglan Castle, and Gwladys ferch Dafydd Gam, and grandson of Dafydd Gam, an adherent of King Henry V of England. His father had been an ally of Richard of York, and Herbert supported the Yorkist cause in the Wars of the Roses. In 1461 Herbert was rewarded by King Edward IV with the title Baron Herbert of Raglan (having assumed an English-style surname in place of the Welsh patronymic), and was invested as a Knight of the Garter.

Soon after the decisive Yorkist victory at the Battle of Towton in 1461, Herbert replaced Jasper Tudor as Earl of Pembroke which gave him control of Pembroke Castle – and with it, he gained the wardship of young Henry Tudor. However, he fell out with Lord Warwick "the Kingmaker" in 1469, when Warwick turned against the King. Herbert was denounced by Warwick and the Duke of Clarence as one of the king's "evil advisers". William and his brother Richard were executed by Warwick in Northampton, after the Battle of Edgcote, which took place in South Northamptonshire, near Banbury.

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 of Ewyas.

Marriage and children He married Anne Devereux, daughter of Walter Devereux, Lord Chancellor of Ireland, and Elizabeth Merbury. They had at least ten children:
