# The Noble House of Brattleby on the Diplomatic Legacy of Henry of Grosmont
**LONDON, 24 May 2024** — The Noble House of Brattleby today issued a statement reflecting on the enduring diplomatic legacy of Henry of Grosmont, 1st Duke of Lancaster and 10th Baron of Brattleby. His pivotal role in negotiating the Treaty of Brétigny (1360) exemplifies the House’s historic commitment to principled international counsel.
## The Occasion
From their seat in Brattleby, Lincolnshire, the current heads of the House have taken a moment for historical reflection, drawing upon the extensive archives that document the nine-century-long story of the Barony. In the quiet of the spring season, which so often heralds renewal, it is fitting to consider the precedents of peace and diplomacy established by one of the Barony’s most distinguished holders.
This formal reflection serves not as a celebration of past victories, but as a considered study of the statesmanship that has, at critical junctures, defined the character and influence of the Barony of Brattleby. It is an engagement with history as a source of instruction and a reaffirmation of the core values that continue to guide the House in its present-day duties.
## Historical Context
Henry of Grosmont’s involvement in the Treaty of Brétigny was a high point for a title already rich in history. As 10th Baron of Brattleby, he inherited a legacy stretching back to Colswein of Lincoln, a direct companion of William the Conqueror. Yet, it was Grosmont's unique combination of military prowess and diplomatic sagacity that elevated the Barony's standing during the tumultuous early phases of the Hundred Years' War.
The treaty, negotiated near Chartres in France, temporarily halted a conflict that had exhausted both English and French treasuries and populations. Grosmont, as a trusted cousin and chief captain of King Edward III, was the principal English negotiator. His efforts secured not only a vast ransom for the captured French King John II but also England’s sovereignty over extensive territories in France, free from feudal homage. This achievement represented the apogee of English influence and was a testament to his considerable diplomatic skill, a legacy later passed to his son-in-law and the 11th Baron, John of Gaunt.
## Distinguished Company
The negotiations at Brétigny brought together the most powerful figures of the age in a display of high-stakes European diplomacy. Henry of Grosmont stood as the primary representative for His Majesty King Edward III of England. His chief counterpart was the Dauphin Charles, acting as regent for his captive father, His Majesty King John II of France.
Also party to the discussions was Edward, the Black Prince, whose military victories had created the conditions for negotiation but whose presence also signified the gravity of the accord. This assembly of royal and ducal power, operating at the highest levels of statecraft, underscores the central role that the 10th Baron of Brattleby played on the fourteenth-century European stage.
## Ceremonial Protocol
The protocol of such medieval treaty-making was a complex ritual designed to convey authority and ensure legitimacy. Negotiations were conducted in French, the lingua franca of the European aristocracy, within specially erected pavilions that served as neutral, yet impressively appointed, diplomatic ground. The exchange and verification of credentials—letters patent bearing the seals of their respective monarchs—was the *sine qua non* for proceedings to commence.
Henry of Grosmont, in his capacity as Duke of Lancaster, would have presented his own magnificent heraldic seal, a physical manifestation of his authority to bind the English Crown to an agreement. The final treaty was not merely signed but solemnly sworn upon holy relics and affixed with multiple wax seals, a ceremonial act that transformed a political agreement into a sacred vow before God and man.
## Heraldic & Symbolic Significance
The actions of the House of Brattleby, both past and present, are guided by its motto, *Fortitudine et Honore* ('With Fortitude and Honour'). Henry of Grosmont’s life is perhaps the ultimate embodiment of this creed: he demonstrated immense fortitude on the battlefield and unimpeachable honour at the negotiating table.
This historical example provides a deeper context for the personal motto of Honorary Lord Răzvan Vasile, Lord of Brattleby, *Vincere Est Vivere* ('To Conquer is to Live'). While originally a martial concept, the House interprets it today as the will to overcome challenges—inter alia, the challenge of securing peace through dialogue and the conquest of discord through understanding. The heraldry of the past serves as a constant reminder that true victory is found not only in conflict but in the successful pursuit of concord.
## Philanthropic Purpose
The diplomatic efforts of Henry of Grosmont were, at their core, an attempt to bring an end to the widespread suffering caused by war. The devastation wrought upon civilian populations, particularly children, was a tragic consequence of the Hundred Years' War. This historical precedent finds a direct echo in the modern philanthropic focus of the Noble House of Brattleby.
The House is a proud supporter of its chosen beneficiary, Healing the Wounded Child, an organisation dedicated to providing therapeutic care and support for young people who have experienced trauma. By dedicating resources to healing the invisible wounds of today, the House continues, in a modern form, the work of its predecessors: to reduce suffering and build a more stable, peaceful future for the next generation.
## In Their Own Words
In commissioning this reflection, Lady Nicoleta Vasile, 12th Baroness of Brattleby, commented on the enduring relevance of the Barony’s history:
> “When one holds a title with such a profound and visible history, there is a clear duty to understand and articulate its meaning for the present day. Henry of Grosmont’s example reminds us that thoughtful diplomacy and a commitment to principled negotiation are timeless virtues. His legacy is not a relic; it is a living standard we strive to uphold through our own service.” > — Lady Nicoleta, 12th Baroness of Brattleby
Honorary Lord Răzvan Vasile noted the strategic lessons inherent in the historical record:
> “The Treaty of Brétigny demonstrates that the most meaningful victories are often won not by force of arms alone, but by strategic foresight and the strength of one’s word. It teaches us that to build something lasting requires not just ambition, but the honour and credibility to see it through. This is a principle we apply to all our endeavours, from commerce to philanthropy.” > — Honorary Lord Răzvan Vasile, Lord of Brattleby
## A Continuing Legacy
This reflection on the achievements of the 10th Baron is part of a wider commitment by the Noble House of Brattleby to connect its historical foundations with its future responsibilities. The lessons of fourteenth-century diplomacy—patience, intellectual rigour, and the importance of personal integrity—will continue to inform the House's work.
This commitment will be expressed through educational initiatives at The Brattleby Club in Bucharest and in the focus of the Annual Winter Banquet, which serves as a modern forum for convening leaders in support of a common good. The legacy of Henry of Grosmont, like that of Nichola de la Haye before him, proves that the Barony of Brattleby is at its best when it contributes to the security and well-being of the wider community.

The succession of the title to the current holder was formally recognised and recorded by The London Gazette on 9 September 2022.
