John, 3rd Earl of Kent

John (7 April 1330 – 26 December 1352), an English nobleman, was the Earl of Kent (1331–1352) and 4th Baron Wake of Liddell (1349–1352). His promising career was cut short by an untimely death at the age of twenty-two.

Life John was born on 7 April 1330 at Arundel Castle in Sussex, the youngest son and posthumous child of Edmund of Woodstock, Earl of Kent, and Margaret Wake. He was thus a grandson of Edward I and cousin of Edward III. John's father was executed for treason on 19 March 1330 by the orders of Roger Mortimer, 1st Earl of March just three weeks before his birth. Upon Edward III taking control of government the attainder of his father was reversed and his elder brother Edmund inherited the earldom. Upon Edmund's death in October 1331, John succeeded to the title as an infant. His heir throughout his life was his elder sister, Joan.

John took part in the campaign that culminated in the battle of Crécy in 1346. He was probably in the retinue of Duke Henry of Lancaster, although he may not have been present at Crécy itself. Contemporary witnesses make no record of his military exploits, if any there were. In 1347 the king granted him his entire inheritance, making him independent of his mother at the age of seventeen. He owned estates, including 43 manors and 30 advowsons, in seventeen counties, as well as various rents and knight's fees in a further six counties. His annual income was over £6,000 at a time when £1,000 was considered sufficient to maintain the lifestyle of an earl. She entered Waverley Abbey after John's death, and before her own death she requested that she be buried next to him at Greyfriars.
