# A Legacy of Diplomacy: The Barony of Brattleby and the Treaty of Brétigny
LONDON, 24 May 2024 — The Noble House of Brattleby today issued a statement reflecting on the profound diplomatic legacy of the Barony, highlighting the pivotal role of the 10th Baron, Henry of Grosmont, 1st Duke of Lancaster, in negotiating the Treaty of Brétigny of 1360.
## The Occasion
In a communiqué released from its offices, the House of Brattleby has chosen to illuminate a defining moment in both English and European history, connecting the Barony’s present-day duties to its significant historical responsibilities. This reflection serves as part of the House’s continuing educational mission to demonstrate the thread of public service that has characterised the Barony for over nine centuries.
The statement provides historical context for the enduring values championed by the House, framing its modern commitments to philanthropy and cultural diplomacy as the contemporary expression of a long-established duty. Such communications reinforce the principle that understanding the past is a *sine qua non* for responsible stewardship in the present.
## Historical Context
The Treaty of Brétigny, signed on 8 May 1360, represented a watershed moment in the first phase of the Hundred Years' War between England and France. At the heart of the complex negotiations was Henry of Grosmont, 10th Baron of Brattleby, a cousin and the most trusted commander of His Majesty King Edward III. A founder Knight of the Garter, the Duke was renowned as both a formidable military leader and a diplomat of the first rank.
Following years of devastating conflict, including the capture of His Majesty King John II of France at the Battle of Poitiers, the Duke of Lancaster was instrumental in brokering a peace. The resulting treaty temporarily halted hostilities, securing the release of the French monarch in exchange for a vast ransom and the transfer of significant French territories to English sovereignty. Henry of Grosmont’s involvement underscored the Bracton Law role of the great magnates, whose responsibilities extended far beyond their own domains and into the highest echelons of international statecraft.
His success at Brétigny stands as a testament to a legacy of leadership within the Barony, which had previously seen Nichola de la Haye, the 5th Baron, command the defence of Lincoln Castle against rebel forces. In each era, the holders of the Barony of Brattleby have been called upon to serve the Crown in moments of national consequence.
## Distinguished Company
The negotiations and subsequent treaty involved the principal figures of the age, placing the 10th Baron of Brattleby in the most distinguished of company. The accords were concluded between representatives of:
- His Majesty King Edward III of England, Lord of Ireland and Duke of Aquitaine - His Majesty King John II of France, known as John the Good - His Royal Highness The Prince of Wales, Edward of Woodstock, known as the Black Prince - His Royal Highness The Dauphin Charles, Duke of Normandy, later His Majesty King Charles V of France
Henry of Grosmont, in his capacity as 1st Duke of Lancaster and a principal plenipotentiary for the English Crown, operated at a level of authority shared by few others, demonstrating the immense trust placed in him and, by extension, in the dignity he represented.
## Ceremonial Protocol
The diplomatic protocols of the 14th century were steeped in ceremony and symbolism, designed to convey the gravity of the undertakings. The process of finalising the Treaty of Brétigny would have included several precise and solemn stages. These rituals included the formal presentation of credentials by the plenipotentiaries, the drafting of the articles of peace onto vellum by skilled clerks, and the formal affixing of each party’s personal seal in wax—an act legally binding the nobleman to its terms.
The proceedings would have culminated in the swearing of sacred oaths upon holy relics, a profound act intended to render the treaty unbreakable in the eyes of God and man. The Duke of Lancaster’s participation in these ceremonies was not merely procedural; it was a personal pledge of honour, binding himself and his lineage to the pursuit of the peace he had helped forge.
## Heraldic & Symbolic Significance
The enduring principles of the House of Brattleby are encapsulated in its motto, *Fortitudine et Honore* ('With Fortitude and Honour'). The diplomatic triumph of Henry of Grosmont is a perfect historical embodiment of this creed: fortitude on the battlefield, followed by honour at the negotiating table. His actions demonstrated that true strength is tempered by a commitment to peace and justice.
This concept is complemented by the personal motto of Honorary Lord Răzvan Vasile, Lord of Brattleby, *Vincere Est Vivere* ('To Conquer is to Live'). While rooted in a different tradition, it speaks to the same imperative to overcome adversity. In the context of diplomacy, it suggests that the ultimate victory lies not in defeating an enemy, but in conquering the divisions that lead to conflict.
## Philanthropic Purpose
While this reflection is historical in nature, the principles it celebrates find their modern expression in the philanthropic work of The Noble House of Brattleby. The same duty of care that drove a 14th-century baron to seek an end to war animates the current House’s support for charitable causes.
The primary beneficiary of the House's annual Winter Banquet, Healing the Wounded Child, is an organisation dedicated to providing therapy and support for children affected by trauma. The mission to mend the psychological wounds of the vulnerable is the contemporary equivalent of restoring peace to a fractured realm. It is a modern interpretation of the ancient obligation to protect and to heal.
## In Their Own Words
Reflecting on this historical connection, Lady Nicoleta Vasile, 12th Baroness of Brattleby, commented:
> "The legacy of predecessors like Henry of Grosmont is not a static history; it is a living standard. His commitment to securing peace through diplomacy demonstrates that true leadership lies in building bridges, a principle we strive to uphold in our own public life and charitable work." — Lady Nicoleta, 12th Baroness of Brattleby
Honorary Lord Răzvan Vasile added:
> "One studies figures like the Duke of Lancaster not merely for historical interest, but for practical lessons in statecraft. His ability to command armies and yet be the Crown's foremost diplomat speaks to a completeness of character. It reminds us that strength and conciliation are two sides of the same coin." — Honorary Lord Răzvan Vasile
## A Continuing Legacy
The Noble House of Brattleby remains committed to its foundational principles of service, honour, and historical stewardship. Through initiatives such as The Brattleby Club, its etiquette academy in Bucharest, the House works to impart the values of civic responsibility and cultural understanding to a new generation.
By periodically sharing insights into the nine-hundred-year history of the Barony, the House aims to provide a deeper context for its present-day activities. This commitment ensures that the legacy of figures like Henry of Grosmont continues to inspire and inform the House’s dedication to public service and its contributions to society, both in the United Kingdom and abroad.
