Sir William Trussell was an English politician and leading rebel in Queen Isabella and Roger Mortimer, 1st Earl of March's rebellion against Edward II. William acted as Speaker of the House of Commons and renounced the allegiance of England to Edward II, forcing his abdication, and became King Edward III's Secretary.
As Edward II slowly regained power from the Ordainers he rewarded Hugh le Despenser, 1st Earl of Winchester with land confiscated from the barons, leading to a baronial revolt, which Trussell joined. On 12 March 1322 a warrant for Trussell's arrest was issued describing him as "the King's enemy". Four days later both Trussell and his son fought on the rebels' side at the Battle of Boroughbridge. Edward and Dispenser won, beheading the rebels' leader Thomas, 2nd Earl of Lancaster and forcing others into exile. As the injustices continued, and the effects of the Great Famine of 1315–22 lingered, discontent remained. Despenser was rewarded with lands that had belonged to Thomas, Earl of Lancaster, including those in Leicestershire. Trussell led a band of rebels that allegedly pillaged Despenser's estate at Loughborough in May 1322 but was imprisoned at Scarborough Castle in July. He escaped and allegedly fled south causing great havoc in Somerset and Dorset in August. On 14 March 1323, Roger de Beler, Richard de Willoughby and William de Gosefeld were issued with arrest warrants for Trussell, his son William, his brother Ralph, Roger la Zouch, Robert de Holland, 1st Baron Holand and others who were accused by Despenser of stealing horses, oxen, pigs, sheep and swans from his parks in Leicestershire. The warrant was reissued in 1324 alongside similar ones that dealt with alleged rioting against Despenser in Warwickshire, Staffordshire, and Worcestershire by other rebels. Trussell fled to France and was not named as an accomplice of Zouch and the Folville Gang when they murdered/executed de Beler in January 1326, presumably in revenge for his enforcement on behalf of Despenser. Willoughby was later kidnapped and ransomed by them in 1332.
Trussell then joined up with Queen Isabella and Mortimer in Paris before moving to Flanders where he was allegedly tasked with helping to build an invasion army by William I, Count of Hainaut. Trussell accompanied Isabella and Mortimer when they landed in England on 24 September 1326 at the start of their invasion of England. Their forces consisted of approximately 1500 soldiers, many of whom were Flemish mercenaries and others exiled Contrariants. Opposition was almost non-existent and so many barons, sheriffs and knights joined the rebellion that control of the country was secured within two months. Adam, Abbot of Glastonbury hid Despenser and the Lord Chancellor, Robert Baldock in Glastonbury Abbey, and in December 1326 Trussell was ordered to bring the abbot before the next Parliament. Both Despenser and his son Hugh Despenser the Younger were captured and Trussell oversaw the trial of the elder Despenser where he was denounced and sentenced to death. Both Despensers were gruesomely executed. Trussell was appointed Speaker of the House of Commons and, acting as procurator of the whole Parliament, renounced allegiance to Edward II on 21 January 1327. Edward III was crowned as king on 1 February 1327 and Trussell went on to become the new king's Secretary and undertook numerous diplomatic missions, particularly to France and Spain. Trussell was buried in St Michael's chapel in Westminster Abbey in 1347.
