This William, son of Hugh, second Earl, at first Bishop of London, afterwards raised to the archiepiscopal see of Canterbury, possessed so fully the hereditary courage of his opinions that he not only resolutely opposed the weighty influence of the Duke of Lancaster and Lord Percy of Northumberland, when exercised by them in favour of John Wicliffe, but also as Adam, Archdeacon of Usk, pathetically declares: “Eciam a facie istius regis Ricardi, ille vir perfectissimus Willelmus Cantuariensis Archiepiscopus quia hujus modi taxe resistere volens.” The strength of the superlative epithet is justified by the said tax having been levied solely against the clergy. But the prosperity of the Courtenays, as of most other noble families in England, was rudely disturbed by the outbreak of civil strife—the Wars of the Roses. Supporting strongly the House of Lancaster, they shared in undue proportions the calamities which befel that party, three successive Earls of Devon, the sons of Thomas, fifth in title, giving their lives for the cause they supported. Thomas, the elder of the three, taken at Towton, was soon after executed, as historians say, to appease the ghost of the Duke of York. A few years later, Henry, his brother, met the same fate; while John, the youngest, fell in the disastrous battle of Tewkesbury, the great estates of the family being escheated by the King. Yet once more, with the triumph of Henry VII., the fortunes of the ancient house revived. The King annulled the attainder and restored the ancestral domains to the faithful noble who had followed him into exile and fought by his side at Bosworth Field, subsequently sanctioning also the marriage of the eldest son, Sir William Courtenay, with Katherine, the younger daughter of the late King Edward IV.; though this royal alliance, as was often the case in such connections, only led to suspicion on the part of the reigning monarch and calamity to the aspiring bridegroom. In the succeeding reign, Henry, the child of this marriage, stood high in the favour of the monarch. As the boon companion of his cousin the King, he tilted with him at Greenwich; as his brother-in-arms, he fought at the Battle of the Spurs; in the office of Lord High Steward, he presided over the trial of those persons who had fallen under the Royal displeasure; and finally the honour of a Marquisate was bestowed, and Henry, seventh Earl of Devon, became the first Marquis of Exeter.
