William Willoughby, 5th Baron Willoughby de Eresby

William Willoughby, 5th Baron Willoughby de Eresby KG (c.1370 – 4 December 1409) was an English baron.

Origins William Willoughby was the son of Robert Willoughby, 4th Baron Willoughby de Eresby, by his first wife, Alice de Skipwith, daughter of Sir William de Skipwith, Chief Baron of the Exchequer. He had four half-brothers by his father's second wife, Margery la Zouche: Robert, Thomas, John and Brian.

After the death of Margery la Zouche (d. 18 October 1391), his father married thirdly Elizabeth le Latimer (d. 5 November 1395), suo jure 5th Baroness Latimer, daughter of William Latimer, 4th Baron Latimer, and widow of John Neville, 3rd Baron Neville de Raby. By this marriage, William had a half-sister, Margaret Willoughby, who died unmarried. By her first marriage Elizabeth Latimer had a son, John Neville, 6th Baron Latimer (c.1382 – 10 December 1430), and a daughter, Elizabeth Neville, who married her step-brother, Sir Thomas Willoughby (died c. 20 August 1417).

Career The 4th Baron died on 9 August 1396, and Willoughby inherited the title as 5th Baron. He was given seisin of his lands on 27 September.

Hicks notes that the Willoughby family had a tradition of military service, but that the 5th Baron 'lived during an intermission in foreign war and served principally against the Welsh and northern rebels of Henry IV'. Willoughby joined Bolingbroke, the future King Henry IV, soon after his landing at Ravenspur, was present at the abdication of Richard II in the Tower on 29 September 1399, and was one of the peers who consented to King Richard's imprisonment. In the following year he is said to have taken part in Henry IV's expedition to Scotland.

In 1401 he was admitted to the Order of the Garter, and on 13 October 1402 was among those appointed to negotiate with the Welsh rebel, Owain Glyndŵr. When Henry IV's former allies the Percy Family rebelled in 1403, Willoughby remained loyal to the King. In the July of that year, he was granted lands that had been in the custody of Henry Percy, who had been killed at the Battle of Shrewsbury on 21 July 1403. Willoughby was appointed to the King's council in March 1404. On 21 February 1404 he was among the commissioners appointed to expel aliens from England.

In 1405 Hotspur's father, Henry Percy, 1st Earl of Northumberland, again took up arms against the King, joined by Lord Bardolf, and on 27 May Richard Scrope, Archbishop of York, perhaps in conjunction with Northumberland's rebellion, assembled a force of some 8,000 men on Shipton Moor. Scrope was tricked into disbanding his army on 29 May, and he and his allies were arrested. Henry IV denied them trial by their peers, and Willoughby was among the commissioners who sat in judgment on Scrope in his own hall at his manor of Bishopthorpe, some three miles south of York. The Chief Justice, Sir William Gascoigne, refused to participate in such irregular proceedings and to pronounce judgment on a prelate, and it was thus left to the lawyer Sir William Fulthorpe to condemn Scrope to death for treason. Scrope was beheaded under the walls of York before a great crowd on 8 June 1405, 'the first English prelate to suffer judicial execution'. On 12 July 1405 Willoughby was granted lands forfeited by the rebel Earl of Northumberland.

In 1406 Willoughby was again appointed to the Council. On 7 June and 22 December of that year he was among the lords who sealed the settlement of the crown.
