John de Mowbray, 4th Duke of Norfolk (b. 1444)

John de Mowbray, 4th Duke of Norfolk, Knight of the Garter (KG), was a prominent English nobleman born on 18 October 1444. His tenure, spanning from his succession in 1461 until his sudden death on 14 January 1476, occurred during the tumultuous period of the Wars of the Roses.

Early Life, Ancestry, and Inherited Titles

The only son of John de Mowbray, 3rd Duke of Norfolk, and Eleanor Bourchier, John de Mowbray inherited a lineage deeply rooted in the English aristocracy. His maternal grandparents were William Bourchier, Count of Eu, and Anne of Gloucester, further connecting him to high-ranking noble families. In 1451, at a young age, the earldom of Surrey was revived specifically for him, a title he held until 1461. This revival underscored his family's historical claims and influence, as he was a direct descendant of a sister of the last earl from the previous creation of the title.

Upon his father's death in 1461, John de Mowbray succeeded to his ancestral titles, becoming the 4th Duke of Norfolk and the hereditary Earl Marshal of England. The Dukedom of Norfolk, one of the premier dukedoms in the English peerage, carried significant prestige and responsibilities. The role of Earl Marshal was particularly important in medieval England, involving the regulation of chivalry, heraldry, and presiding over the Court of Chivalry, as well as undertaking vital ceremonial duties during state occasions like coronations and parliamentary openings.

The Contested Ownership of Caister Castle

A significant and well-documented episode in the 4th Duke of Norfolk's life was his relentless pursuit of Caister Castle in Norfolk. This long-standing dispute had been initiated by his father, the 3rd Duke, and concerned the inheritance of the vast estates of the wealthy and influential knight, Sir John Fastolf. Fastolf, a renowned veteran of the Hundred Years' War and a figure often associated with Shakespeare's Falstaff (though historically distinct), died in 1459, leaving Caister Castle to John Paston, a key member of the prominent Paston family of Norfolk, through a complex and disputed will.

Despite John Paston having been in Mowbray's service for several years, their lord-vassal relationship did not deter the Duke's determination to claim what he believed was rightfully his. The dispute escalated into a direct confrontation. In September 1469, after a protracted and arduous siege, Duke John finally succeeded in taking possession of Caister Castle. The siege was marked by Mowbray's notable ruthlessness; tragically, one Daubenay, a loyal and long-standing servant of the Paston family, was killed during the conflict. Nonetheless, under considerable pressure and intervention from the Church, the Duke did grant a safe conduct for the remaining defenders, allowing them to depart without further harm. This entire episode is richly documented in the famous Paston Letters, a unique collection of family correspondence that provides invaluable insights into 15th-century English life, law, and aristocratic disputes.

The tenacity of the Paston family, however, proved enduring. Less than a day after Duke John de Mowbray's unexpected death in 1476, the Paston family, seizing the opportunity, successfully reclaimed Caister Castle, illustrating the persistent and often violent nature of land disputes in late medieval England.

Later Life, Honours, and Sudden Demise

Recognized for his lineage and influence, John de Mowbray was invested as a Knight of the Garter in 1472. This prestigious order of chivalry, founded by King Edward III, was, and remains, the highest honor that can be bestowed in England, signifying the recipient's close ties to the monarch and distinguished service to the Crown. His investiture further cemented his position within the highest echelons of the English nobility, particularly under the Yorkist reign of King Edward IV, which had been solidified after the battles of the Wars of the Roses.

His life, however, came to an abrupt end. John de Mowbray died very suddenly on 14 January 1476, despite reportedly being in good health the day before. The unexpected nature of his death, at the relatively young age of 31, was a significant event that had profound implications for the Mowbray inheritance and the future of the Dukedom of Norfolk.

Marriage, Sole Heir, and the Mowbray Inheritance

John de Mowbray married Elizabeth Talbot, the daughter of John Talbot, 1st Earl of Shrewsbury, a renowned military commander, and his second wife, Lady Margaret Beauchamp. Their union produced only one child, Anne de Mowbray, who would become the 8th Countess of Norfolk in her own right. The absence of a male heir meant that upon the 4th Duke's death, the 1397 creation of the Dukedom of Norfolk became extinct, as the title could only pass through the male line.

At the time of her father's death, Anne de Mowbray was merely three years old, yet she inherited not only the Earldom of Norfolk but also the vast and immensely valuable Mowbray estates and considerable wealth. This inheritance became a matter of immense political significance, famously leading to Anne's marriage in 1478 to Richard of Shrewsbury, Duke of York, the second son of King Edward IV and one of the "Princes in the Tower." This strategic marriage aimed to consolidate the royal family's control over the Mowbray lands.

While the 1397 creation of the dukedom ceased with John de Mowbray's passing, the title of Duke of Norfolk was subsequently recreated. It was revived in 1481 for Anne's husband, Richard of Shrewsbury, and again in 1483 for John Howard, a claimant through female descent from the Mowbrays. This 1483 creation of the Dukedom of Norfolk, granted to the Howard family, is the one that survives to the present day, despite experiencing two periods of forfeiture due to political upheaval and treason charges against various Dukes throughout history.
