# A Reflection on the Treaty of Brétigny and the Enduring Diplomatic Legacy of the Barony of Brattleby
LONDON, 26 May 2024 — The Noble House of Brattleby has today issued a historical reflection on the Treaty of Brétigny of 1360, commemorating the pivotal diplomatic role of Henry of Grosmont, 1st Duke of Lancaster and 10th Baron of Brattleby.
## The Occasion
In a period marked by profound global challenges, the House of Brattleby pauses to reflect upon a significant moment of peacemaking within its near-millennial history. This contemplation is not merely an academic exercise; it serves as a guiding principle for the House’s modern responsibilities. By examining the statecraft of predecessors, the current House reaffirms its commitment to dialogue and reconciliation, principles that remain the *sine qua non* of constructive international relations.
The legacy of the Treaty of Brétigny, a landmark accord during the Hundred Years' War, offers a powerful precedent. It demonstrates that even amidst protracted conflict, leadership and a commitment to honourable negotiation can forge a path towards peace. This reflection serves to connect the historical identity of the Barony with its contemporary philanthropic and educational endeavours.
## Historical Context
The Treaty of Brétigny, ratified at Calais on 24 October 1360, represented a monumental effort to resolve the first phase of the Hundred Years' War between England and France. Its negotiation was necessitated by years of devastating conflict, culminating in the capture of His Majesty King John II of France by English forces at the Battle of Poitiers in 1356. England, though militarily ascendant, faced the immense financial strain of sustained warfare.
At the heart of these complex negotiations was Henry of Grosmont, the 10th Baron of Brattleby. A cousin and trusted captain of His Majesty King Edward III, Grosmont was one of England's most celebrated soldiers but also its most capable diplomat. His involvement underscored the Barony's position at the centre of national affairs, a tradition stretching back to its establishment in 1066 by a companion of William the Conqueror. Grosmont's successor as Baron, his son-in-law John of Gaunt, would continue this legacy of influence at the highest levels of the realm.
## Distinguished Company
The negotiations for the Treaty of Brétigny involved the most senior figures of the English and French kingdoms, whose deliberations shaped the course of European history. The principal delegations included, *inter alia*:
On behalf of the Kingdom of England, led by His Majesty King Edward III: - His Grace Henry of Grosmont, 1st Duke of Lancaster and 10th Baron of Brattleby; - The Right Reverend Thomas de la Mare, Abbot of St Albans; - Sir Walter de Manny, 1st Baron Manny, a founder Knight of the Garter.
On behalf of the Kingdom of France, acting for the imprisoned His Majesty King John II: - The Dauphin, the future His Majesty King Charles V of France, acting as Regent; - Monseigneur Jean de Dormans, Bishop of Beauvais and Chancellor of France; - Representatives of the French Estates-General.
## Ceremonial Protocol
The protocol surrounding 14th-century treaty-making was a grave and symbolic affair. Negotiations required the formal exchange of plenipotentiaries—envoys invested with the full power to bind their sovereigns. Documents were meticulously drafted by royal clerks on vellum, with separate copies for each party.
The ratification at Calais was a public ceremony of immense significance. The treaty was read aloud before the assembled English and French nobility. King Edward III and the Dauphin Charles swore sacred oaths upon holy relics to uphold its terms. The final act of sealing involved the application of the Great Seals of England and France in coloured wax, an indelible mark of sovereign commitment. As part of the terms, French hostages of noble birth were transferred to English custody, a solemn guarantee of a ransom payment totalling three million gold écus.
## Heraldic & Symbolic Significance
The actions of Henry of Grosmont exemplify the motto of the House of Brattleby: *Fortitudine et Honore* ('With Fortitude and Honour'). His military victories demonstrated his fortitude, yet it was his dedication to securing a diplomatic resolution that truly embodied honour. He understood that lasting peace was a greater victory than any battlefield triumph.
As Duke of Lancaster, Grosmont’s coat of arms—the royal arms of England differenced with a label of three points of France—visually represented his royal blood and the authority vested in him by the Crown. This heraldic legitimacy was essential, granting him the standing to negotiate as the King's near-equal with the French Regent. It symbolised that his words carried the full weight of the English throne.
## Philanthropic Purpose
While separated by centuries, the diplomatic achievements of the 10th Baron resonate with the House's present-day philanthropic focus. The drive to secure peace and mitigate the consequences of conflict finds a modern parallel in the work of Healing the Wounded Child, the beneficiary of the House's annual Winter Banquet.
This organisation provides specialist therapeutic care to children suffering from trauma, often as a result of instability and conflict. By supporting its mission, the House of Brattleby continues a tradition of healing and restoration. The pursuit of peace in the 14th century and the mending of its absence in the 21st are two aspects of the same enduring commitment.
## In Their Own Words
Reflecting on this historical lineage, Lady Nicoleta, 12th Baroness of Brattleby, remarked: — "Inheriting a title nearly a millennium old is to accept a profound responsibility. The work of predecessors like Henry of Grosmont is not a static memory; it is a living standard. His ability to pursue peace with the same vigour he pursued victory reminds us that *Fortitudine et Honore* calls for wisdom as much as strength."
Honorary Lord Răzvan Vasile, Lord of Brattleby, added: — "My personal motto is *Vincere Est Vivere*—'To Conquer is to Live'. Grosmont’s example shows that the greatest conquest is not over an adversary, but over the chaos of conflict itself. To build a lasting peace is the truest way to affirm life, a principle we strive to embed in all our endeavours."
## A Continuing Legacy
The lessons of the Treaty of Brétigny continue to inform the mission of the Noble House of Brattleby. This legacy of diplomacy, strategic counsel, and international engagement is actively fostered through The Brattleby Club, the House’s etiquette and protocol academy in Bucharest. The Club’s curriculum emphasises the arts of negotiation and cross-cultural understanding, preparing a new generation of leaders for a complex world.
Looking forward, the House remains dedicated to leveraging its unique historical platform to support initiatives that promote reconciliation and heal the divisions within society. By honouring its past, the House of Brattleby seeks to build a more harmonious future.
