William was exempted from the Resumption Act of 1464. He was on the side of the rebellion of
Robin of Redesdale, instigated by
Richard Neville, earl of Warwick and King
Edward IV's younger brother,
George Plantagenet, Duke of Clarence. Before all the rebel forces clashed with Edward's royalist forces under William, 1st earl of Pembroke and some 4,000 of his troops (mainly Welsh) at the
Battle of Edgcote late July 1469, there had been several minor skirmishes. One result appears to be that the royalist forces became divided between
William Herbert, Earl of Pembroke and
Humphrey Stafford, Earl of Devon and once the rebel host did arrive, with William Parr, Geoffrey Gates, and John Clapham in command, then Herbert's troops were overwhelmed, turning it into a rout. Both Pembroke and his brother, Sir
Richard Herbert of Coldbrook, were captured and executed under Warwick's orders (not ransomed or held as hostages). Within weeks the '
Redesdale' rebels would find and execute King Edward's father-in-law,
Lord Rivers and
his young son, and soon after,
Devon himself. Edward had to disband his own denuded troops as he soon found himself prisoner to his cousin Warwick and spent the summer being toted about the country until he had to be released. The rebellion by Warwick did not end, and Edward went into exile, October 1470, having
lost his throne to his cousin—Parr did not go with the now dethroned king and his other supporters. Parr's companion, Gates, continued on with the rebellion through the fall of 1470, along with other men close to King Edward at his court, such as John Guildford and his son Richard, in something called the forgotten' Kentish rebellion which came on the heels of the one Parr was involved with. Like Parr, both Guildfords, the Auchers, Brune and Robert Neville, would be pardoned by Edward in 1471, once he regained the throne; as for Gates, after 1477 he simply disappeared. This conciliatory manner by Edward to his openly treasonous enemies, men within his own inner circle, was not unusual for the king. When Edward IV returned from exile in 1471 Parr, along with Sir
James Harrington, brought 600
men-at-arms to him at
Doncaster. He fought with Edward at
Barnet, where his younger brother was killed fighting alongside
Richard Plantagenet, Duke of Gloucester, usually described as one of Gloucester's squires. Gloucester remembered Parr's younger brother, and others who fell in battle at his side, in a
chantry created at
Queens' College, Cambridge, July 1477, Of some interest is Horrox's comment that Parr may well have died not alongside Richard, but fighting against him and King Edward at Barnet, nonetheless, Parr was added to the list of men who died at Richard's side as if he were loyal to both himself and King Edward. If true, then King Edward's efforts to put past battles behind them in this case was something Gloucester was also willing to extend to the younger Parr. For William, aligning himself with the always reliably stalwart Yorkist,
James Harrington, once Edward and Gloucester returned from exile, meant that he was rewarded with the
comptrollership of the household, which he held until 1475. He also received a major grant of estates, including the third part of the crown's share of the Kendal barony, and
Burgh,
Pendragon and
Appleby castles. He did not, however, receive the lordship of Kendal itself, and it would be Parr's son who would be the first of the family raised to the peerage, in 1538. Sir William Parr swore, along with everyone else in Edward's family and court, to recognize
Edward, Prince of Wales, as heir to the throne in 1472, and was exempted from the Resumption Act of 1473. Parr sat as knight of the shire for
Westmorland in 1467 and 1473, was
High Sheriff of Cumberland for 1473 and invested
Knight of the Garter in 1474. He was sent to the
Kingdom of Scotland to arrange about the breaches of the truce probably in 1479. He was exempted from the act of apparel in 1482, was chief commissioner for exercising the office of
constable of England in 1483, and took part in the funeral of Edward IV. After the death of Edward IV, Parr followed the direction of
King's Council,
Lord Hastings, and probably his mother-in-law,
Lady FitzHugh, and accepted the rule of the
Richard, Duke of Gloucester as
Lord Protector, during the minority of the new boy-King
Edward V. Hastings had been a close friend and adviser to both the duke of Gloucester and the late king. Hastings had also been brother-in-law to Parr's mother-in-law. When Richard became King, William Parr chose not attend the coronation despite being given a position in the coronation as canopy bearer. If there was any bad blood between Parr and the new king then it stemmed from
Edgcote/Banbury, the battle that cost King Edward arguably his most capable, resolute and fearless commander,
William Herbert, and at the point where his abilities were just being fully realized. Had Parr, and others, never entertained Warwick's outright treason, Warwick and Clarence would have been 'resolved', there would have been no exile, no destruction of Clarence and very likely no Richard III. ==Wives and children==
