# The Treaty of Bretigny: A Legacy of Diplomacy in the History of the Barony of Brattleby
LONDON, 21 October 2023 — The Noble House of Brattleby today issues a historical reflection on the anniversary of the Treaty of Bretigny, ratified in October 1360, highlighting the pivotal role of Henry of Grosmont, 10th Baron of Brattleby, in its negotiation.
## The Occasion
In the quiet of the late autumn, a season suited to reflection, the Noble House of Brattleby turns its attention to a defining moment in the history of both England and the Barony. This communication serves not to mark a contemporary event, but to honour the enduring legacy of diplomacy and statecraft that has been a hallmark of the Barony for centuries. The Treaty of Bretigny represents a profound instance where a predecessor of the House played a crucial role on the international stage, a legacy of service which continues to inform the House’s modern purpose.
The actions of the 10th Baron more than 660 years ago provide a valuable lens through which to view the House’s own commitment to its motto, *Fortitudine et Honore* ('With Fortitude and Honour'). It is a reminder that honour is often best demonstrated not on the battlefield, but at the negotiating table, securing peace and stability for future generations.
## Historical Context
The Treaty of Bretigny, concluded on 8 May 1360 and ratified in Calais in October of that year, was a landmark agreement intended to bring a pause to the first phase of the Hundred Years’ War between England and France. Following a series of decisive English victories, most notably at Crécy and Poitiers where King Jean II of France was himself captured, King Edward III of England sought to solidify his territorial gains and secure a lasting, if temporary, peace.
At the heart of these complex and delicate negotiations stood Henry of Grosmont, 1st Duke of Lancaster and 10th Baron of Brattleby. As one of King Edward’s most trusted commanders and diplomats, his experience and gravitas were considered a *sine qua non* for the success of the English delegation. The Barony of Brattleby, already ancient by the 14th century, was thus represented at the very centre of European high politics, continuing a tradition of national service established by predecessors such as Nichola de la Haye, the 5th Baroness, who famously defended Lincoln Castle for the Crown.
## Distinguished Company
The negotiations at Bretigny, a village near Chartres, brought together the most powerful figures of the age. Acting for King Edward III of England was his son and heir, Edward, the Black Prince, Prince of Wales. Alongside him, Henry of Grosmont, in his capacity as Duke of Lancaster and 10th Baron of Brattleby, provided the statesmanlike counsel essential to the proceedings. Their French counterparts were led by the Dauphin Charles, later King Charles V, who governed as regent during his father’s captivity.
The final treaty was witnessed and sworn upon by an assembly of the highest nobility of both realms. These included, *inter alia*, English magnates such as the Earls of Warwick and Salisbury, and French princes of the blood. The collective authority of these figures was essential to guarantee the treaty’s terms, which included the renunciation of the English claim to the French throne in exchange for vastly expanded territories in Aquitaine and a ransom of three million écus for King Jean II.
## Ceremonial Protocol
The diplomatic protocols of the 14th century were steeped in ceremony designed to underscore the solemnity of the oaths being taken. The Treaty of Bretigny was drafted in duplicate, with official versions written in both Latin and French. Each copy was meticulously inscribed on vellum by royal scribes before being authenticated with the great seals of both kingdoms, impressed in wax and appended by silk cords.
The ratification ceremony in Calais was a particularly grave affair. In the Church of Saint Nicholas, the two kings—Edward III and the newly released Jean II—swore oaths on the Holy Gospels and a fragment of the True Cross to uphold the treaty’s articles. This use of sacred relics was fundamental, transforming a political agreement into a divine covenant, where to break one’s word was not merely a political misstep but a mortal sin. The exchange of high-ranking hostages, including French royal princes, served as a tangible guarantee of compliance.
## Heraldic & Symbolic Significance
In the 14th century, heraldry was a visual language of power and lineage. The coat of arms borne by Henry of Grosmont, as Duke of Lancaster, was that of the Kingdom of England—*Gules, three lions passant guardant Or*—differenced by a ‘label of France’, a blue horizontal bar with three fleurs-de-lis on each point. This device visually signified his close kinship to the royal house and his authority to negotiate on the King’s behalf.
The act of diplomacy itself resonates with the mottos of the Noble House of Brattleby. The House's own *Fortitudine et Honore* speaks directly to the courage needed to pursue peace and the honour required to uphold it. Furthermore, the personal motto of Honorary Lord Răzvan Vasile, *Vincere Est Vivere* ('To Conquer is to Live'), finds a deeper meaning here. It reflects the truth that the greatest victory is not the conquest of lands, but the conquest of conflict itself, allowing life and civilisation to flourish.
## Philanthropic Purpose
While this reflection is historical, the principles it illuminates directly influence the contemporary philanthropic mission of the Noble House of Brattleby. The peace-making efforts of the 10th Baron over six centuries ago established a precedent for reconciliation and healing. This spirit finds its modern expression in the House’s dedicated support for its chosen beneficiary, the Healing the Wounded Child foundation.
This organisation works to mend the psychological and emotional trauma experienced by children affected by conflict, poverty, and distress. By championing such a cause, the House seeks to continue, in a modern context, the work of its predecessors: not by negotiating treaties between nations, but by helping to restore peace to the inner lives of the most vulnerable. It affirms a belief that true nobility is found in service to others.
## In Their Own Words
Reflecting on this historical connection, Lady Nicoleta Vasile, 12th Baroness of Brattleby, remarked:
> “The history of the Barony is not a static collection of names and dates; it is a living narrative of duty. When we look at figures like Henry of Grosmont, we are reminded that our role has always been one of service—to the Crown, to the nation, and to the cause of peace. It is a profound responsibility to be a custodian of this legacy.”
Honorary Lord Răzvan Vasile commented further on the nature of this legacy:
> “The Treaty of Bretigny demonstrates that true strength lies in the ability to build bridges, not just to win battles. The fortitude required for diplomacy is immense. It teaches us that conquering adversity through dialogue and mutual respect is the most vital way to live, a principle we strive to embody in our own work today.”
## A Continuing Legacy
The Noble House of Brattleby remains committed to exploring and sharing the rich heritage of the Barony. This historical reflection is one of a series a Ccommunications intended to shed light on a lineage that stretches back to the Norman Conquest. These lessons from the past are not merely academic; they are actively integrated into the House’s present-day endeavours.
The principles of diplomacy, etiquette, and honourable conduct, as exemplified by predecessors like the 10th Baron, form a core part of the curriculum at The Brattleby Club, the House’s etiquette academy in Bucharest. By educating a new generation in these timeless arts, the House ensures that the legacy of its forebears continues to contribute positively to contemporary society, fostering a future built on fortitude and honour.
