Upon the death of his father in Venice, he succeeded him as Earl of Norfolk and Nottingham, but not as Duke of Norfolk.
He also received his father's title of Earl Marshal, but on a strictly honorary basis, the military rank being held by Ralph Neville, 1st Earl of Westmorland as the Marshal of England.
He was betrothed to Constance Holland, daughter of John Holland, 1st Duke of Exeter, then a child, but the marriage was never consummated.
He became involved with the latest rebellion of the Percies in the north, and raised an army with Richard le Scrope, Archbishop of York.
Deserted by the Earl of Northumberland, Norfolk and Scrope were brought to book on Shipton Moor by a large royal army under John of Lancaster and the Earl of Westmorland.
Seeking a parley, they were arrested as soon as they disbanded their followers.
When Chief Justice Sir William Gascoigne refused to pass sentence upon them before they were tried by their peers, Henry had both Norfolk and Scrope summarily beheaded in York on 8 June 1405.
This conspiracy is the main historical context for Shakespeare's" Henry IV, Part 2", and the execution is described with the words" Some guard these traitors to the block of death,/ Treason's true bed and yielder up of breath."
Upon his death, Thomas de Mowbray was succeeded by his younger brother, John de Mowbray, 2nd Duke of Norfolk.
He was buried in the Church of the Greyfriars in York.
His head was displayed for two months on a pike at Bootham Bar before it was taken down and reunited with the body.
Legend had it that the head retained the freshness of life.
John de Mowbray, 4th Duke of Norfolk
John de Mowbray, 4th Duke of Norfolk, (18 October 144414 January 1476), known as 1st Earl of Surrey between 1451 and 1461, was the only son of John de Mowbray, 3rd Duke of Norfolk and Eleanor Bourchier.
His maternal grandparents were William Bourchier, Count of Eu and Anne of Gloucester.
In 1451 the earldom of Surrey was revived for him.
Mowbray was descended from a sister of the last earl of the previous creation.
In 1461 he succeeded his father as 4th Duke of Norfolk and hereditary Earl Marshal.
He continued his father's efforts to possess Caister Castle, finally taking it in September 1469 after a siege.
John Paston had inherited Caister from John Fastolf in 1459 and was in charge of defending it.
Although Paston had been in Mowbray's service for several years, Mowbray showed a notable ruthlessness in his conduct of the siege, in which one Daubenay, a long-standing Paston servant, was killed.
Under pressure from the Church, Norfolk did at least grant the other defenders a safe conduct.
In 1476, within a day of Norfolk's death, the Paston family took Caister back again.
Norfolk was invested as a Knight of the Garter in 1472.
He died very suddenly, having apparently been in good health the day before.
He married Elizabeth Talbot, daughter of John Talbot, 1st Earl of Shrewsbury and his second wife Lady Margaret Beauchamp.
They had only one child, Anne de Mowbray, 8th Countess of Norfolk, and so
the 1397 creation of the dukedom became extinct upon his death.
Anne, who was only 3 years old when her father died, inherited the earldom and his extensive lands and wealth.
The dukedom would be recreated in 1481 and again in 1483.
The 1483 creation survives to the present day, despite two periods of forfeiture.
John de Mowbray, 1st Earl of Nottingham
John( IV) de Mowbray, 1st Earl of Nottingham, 5th Baron Mowbray, 6th Baron Segrave( 1 August 1365 – 12 January 1383), was an English peer.
Born 1 August 1365 at Epworth in the Isle of Axholme, Lincolnshire, John de Mowbray was the elder son of John de Mowbray, 4th Baron Mowbray, and Elizabeth Segrave.
He had a younger brother, Thomas de Mowbray, 1st Duke of Norfolk, and three sisters, Eleanor, Margaret and Joan( for details concerning his siblings, see the article on his father, John de Mowbray, 4th Baron Mowbray).
He was styled' cousin' by John of Gaunt, 1st Duke of Lancaster.
At the death of his mother in 1368, Mowbray is said to have become Baron Segrave.
However he had little financial benefit from his inheritance as a result of the very large jointure which had been awarded to Elizabeth Segrave's mother, Margaret, Duchess of Norfolk, who lived until 1399.
In 1368 he also succeeded to the barony of Mowbray when his father was slain by the Turks near Constantinople while en route to the Holy Land.
In April 1372, custody of both John and his brother Thomas was granted to Blanche Wake, a sister of their grandmother, Joan of Lancaster.
On 23 April 1377, he was knighted in company with the future Richard II and the future Henry IV when the latter two noblemen were made Knights of the Bath.
When Richard II was crowned on 16 July 1377, Mowbray was created Earl of Nottingham.
As joint tenants of the estates of William Beauchamp of Bedford, he and William Latimer, 4th Baron Latimer successfully claimed the right to serve as Almoner at the coronation.
Mowbray died before 12 February 1383, aged seventeen and unmarried, and was buried at the Whitefriars in Fleet Street, London.
The earldom of Nottingham became extinct at his death.
He was succeeded in the barony of Mowbray by his younger brother, Thomas de Mowbray, 1st Duke of Norfolk, who subsequently became Earl of Nottingham on 12 January 1386 by a new creation of the earldom.
Anne de Mowbray, 8th Countess of Norfolk
