Yorkist champions Salisbury and Warwick became the most important supporters of
Richard, Duke of York during the early stages of the
Wars of the Roses. They probably hoped that a
Yorkist seizure of power would bring a favourable resolution of major inheritance disputes involving Warwick, and of a
sporadically violent struggle for preeminence in the north between Salisbury and the Percys. They were also connected to York by marriage, as he had married Salisbury's sister
Cecily; their children included the future kings
Edward IV and
Richard III. In addition to their own wealth and armed following, the Nevilles' heft in this and subsequent conflicts was enhanced by Warwick's position as
Constable of Calais and commissioner for the keeping of the seas. These offices gave him command of England's only significant standing armed force and control of a war-fleet. They also enabled him to develop close ties with the London corporation of the
Merchants of the Staple, a major source of financial support, and to gain popularity with the discontented populace of London and the south-east, especially
Kent, whom Warwick and his allies repeatedly stirred into revolt. York and Salisbury were both killed at the
Battle of Wakefield in 1460, but Warwick helped York's son Edward, Earl of March, to depose
Henry VI and gain the throne as Edward IV in 1461. Among the family's rewards for their support was the elevation of Salisbury's brother, the veteran soldier
William Neville, Lord Fauconberg, as
Earl of Kent. He, Warwick, and Salisbury's younger son
John Neville, now ennobled as
Baron Montagu, directed the suppression of lingering
Lancastrian resistance in the north, where the ousted dynasty clung on for three years after their decisive defeat at the
Battle of Towton in 1461. The Percys were among the principal supporters of the Lancastrian cause, and following the death at Towton of
Henry Percy, Earl of Northumberland, and the final elimination of resistance in the north in 1464, the Nevilles secured their greatest triumph over their rivals, acquiring the earldom of Northumberland for John Neville in 1465.
Disaffection and defection Warwick, now the richest man in England after the king, was the
power behind the throne in Edward's regime during its early years, but the two men later fell out. Their estrangement was due in large part to the king's secret marriage in 1464 to
Elizabeth Woodville. This humiliated Warwick, who had negotiated an agreement with
Louis XI of France for Edward to marry the French king's sister-in-law. Relations were further aggravated by the subsequent influence of the Woodvilles, who successfully opposed Warwick over foreign policy. In 1469 Warwick seized control of government, in conjunction with his brother
George Neville, Archbishop of York, and Edward's own brother
George Plantagenet, Duke of Clarence. Their alliance had been sealed by Clarence's marriage to Warwick's daughter
Isabel. Warwick and Clarence imprisoned the king and sought to rule in his name, but the new regime was unable to impose its authority, and Edward was released. The king refrained from punishing the rebels, but sought to reestablish a northern counterweight to the Nevilles by restoring the earldom of Northumberland to the dispossessed heir,
Henry Percy. This meant depriving John Neville, who had remained loyal to the king when his brothers rebelled, of his title, lands and offices. Edward sought to retain John's allegiance by compensating him with estates in the south-west, the new title of
Marquess of Montagu, and the betrothal of his young son
George Neville to the king's eldest daughter and current heir,
Elizabeth of York. George was made
Duke of Bedford in recognition of his future prospects. All this, however, evidently failed to mollify Montagu. Warwick and Clarence again rebelled in 1470, apparently aiming to put Clarence on the throne. Defeated, they fled abroad, where they made common cause with the exiled Lancastrians, marrying Warwick's daughter
Anne to Henry VI's only son
Edward of Westminster. When Warwick and other leaders of this alliance landed in England to raise revolt once more, they were backed by leading nobles still in England, including Montagu, who turned the troops he had nominally raised for Edward IV against the king. Edward fled the country and Henry VI was briefly restored to the throne, but Edward soon counter-attacked successfully, and Warwick and Montagu were killed at the
Battle of Barnet in 1471.
Aftermath Warwick and Montagu were never formally
attainted, which would have meant the forfeiture of their property. Nonetheless, the victorious Yorkists did not allow the process of inheritance to follow its normal legal course. Montagu's estates should have passed to his son George Neville, Duke of Bedford, along with the considerable portion of Warwick's inherited possessions which had been entailed to heirs male, giving Bedford precedence over Warwick's daughters. However, in practice Bedford was denied his inheritance, while his engagement to Elizabeth of York was cancelled. He would eventually be deprived of his title by an
act of Parliament in 1478, ostensibly on the grounds that he lacked the wealth required to maintain the standing of a duke. The legacy of the Middleham Nevilles instead became the object of dispute between King Edward's brothers: Richard, Duke of Gloucester, and Clarence, who had returned to the family fold before the Battle of Barnet. Clarence, whose claim was founded on his marriage to Isabel Neville, gained the earldoms of Warwick and Salisbury. Gloucester acquired the old Neville estates in the north, establishing his claim by marrying Anne Neville, who had been widowed by Prince Edward's death in the final Lancastrian defeat at the
Battle of Tewkesbury in 1471. The northern lands and clientage inherited from the Nevilles became Gloucester's main powerbase, and he adopted Middleham Castle as his principal residence until his usurpation of the throne as
Richard III in 1483. Reflecting the estrangement between the two branches of the family, the Nevilles of Raby, headed by
Ralph Neville, Earl of Westmorland, had sided with the Lancastrians from the outset. Westmorland's brother
John Neville, Lord of Raby was killed in the defeat at Towton. The line of the Earls of Westmorland survived the wars, but the loss of most of the ancestral estates through their inheritance by the Nevilles of Middleham and their subsequent downfall left the family a much diminished force. Junior lines of the Middleham Nevilles also survived, including the holders of the Latimer and Bergavenny baronies, based, respectively, at Snape and at
Abergavenny Castle.
Edward Neville, Lord Bergavenny had for many years been forcibly deprived of his inheritance by his nephew the Earl of Warwick. During the wars, each of these lines of the family had fought sometimes alongside and sometimes against the core group of Middleham Nevilles led by Salisbury and Warwick. ==Later history==
