The year 1373 marked a significant, though often overlooked, moment in the protracted conflict between England and France. The Treaty of London, signed in this year, was a pragmatic, albeit temporary, attempt to recalibrate the Hundred Years’ War. Its genesis lay in the weariness of both crowns, the ongoing financial strain of sustained warfare, and a discernible shift in the military landscape. This compact, however, was not a groundbreaking peace accord but rather a tactical adjustment, reflecting the complex web of alliances, internal pressures, and strategic objectives that characterized late medieval European politics. Examining the treaty requires an understanding of the preceding decades of conflict and the specific circumstances that compelled both Edward III of England and Charles V of France to seek a temporary respite.
The Hundred Years’ War, which had begun in 1337, was far from a simple territorial dispute. Its roots lay in a complex dynastic claim by Edward III to the French throne, stemming from his maternal lineage. However, underlying this dynastic ambition were economic rivalries, particularly concerning the wealthy region of Flanders, and the traditional antagonisms between the English crown and its continental vassals. By 1373, the war had witnessed a range of successes and setbacks for both sides.
Edward III’s Early Triumphs
The initial decades of the war were arguably more favorable to England. Early English victories, often attributed to superior archery tactics and the effectiveness of English longbowmen, had shattered French military dominance. Battles such as Crécy (1346) and Poitiers (1356) were resounding English successes, resulting in the capture of high-profile French nobility, including King John II of France at Poitiers. These victories had bolstered English morale and significantly weakened the French monarchy, creating a period of internal instability in France.
The French Resurgence Under Charles V
This English ascendancy, however, proved to be unsustainable. The Black Death, which swept across Europe in the mid-14th century, had a profound impact, disrupting societies and economies. In France, the young and relatively inexperienced Charles V, who ascended the throne in 1364, proved to be a shrewd and capable ruler. He implemented a series of reforms and adopted a more strategic approach to warfare.
Military Reforms and Fabian Tactics
Charles V recognized the limitations of direct, pitched battles against the English. He eschewed large-scale confrontations and instead favored a strategy of attrition.
Reorganization of the French Army
Under Charles V, the French military underwent significant reorganization. Existing feudal levies were supplemented and increasingly replaced by more professional mercenary forces, better paid and more strategically deployed.
The Importance ofSiege Warfare
Charles V’s commanders, such as Bertrand du Guesclin, were adept at siege warfare. Instead of engaging in costly pitched battles, they focused on capturing fortified towns and castles, gradually reclaiming territory that had been lost to the English. This tactic starved English garrisons of supplies and weakened their overall control.
Avoiding Decisive Engagements
A key element of Charles V’s strategy was to avoid the kinds of decisive engagements that had proven so disastrous for France. English forces, reliant on their longbowmen and aiming for shattering victories, found fewer opportunities to draw the French into these unfavorable battles. This “Fabian” strategy, named after the Roman general Quintus Fabius Maximus, aimed to gradually wear down the enemy without risking a catastrophic defeat.
Economic Exhaustion and Diplomatic Realities
By the early 1370s, both England and France were experiencing considerable economic strain. The prolonged conflict had drained royal treasuries, necessitating heavy taxation on the populace. For England, maintaining its continental possessions and prosecuting the war required vast expenditure. France, while also burdened, was experiencing a degree of internal recovery and consolidation under Charles V, making continued English aggression increasingly costly without commensurate gains.
The English Perspective: Maintaining Gains and Seeking Leverage
For Edward III, the war was still a matter of dynastic pride and the retention of territories acquired through earlier triumphs. However, the cost of maintaining these holdings, particularly in the face of French resurgence, was substantial. The Treaty of London offered an opportunity to consolidate existing gains, perhaps secure some territorial concessions, and buy time for economic recovery or the reshaping of strategic alliances.
The French Perspective: Reclaiming Sovereignty and Consolidating Power
Charles V, on the other hand, was primarily focused on reclaiming French lands and asserting his sovereign authority. The treaty would allow him to further solidify his control within France, reorganize his administration, and strengthen his military without the immediate threat of major English incursions. It represented a pause, not an end, to his efforts to expel the English from French soil.

Negotiations Leading to the Treaty
The path to the Treaty of London was not a direct one. It involved a series of diplomatic overtures, often mediated by papal legates who sought to bring an end to the persistent conflict. The desire for a truce, if not a lasting peace, was present on both sides, albeit for different strategic reasons.
Papal Mediation and Diplomatic Overtures
The Popes, residing in Avignon during this period, saw themselves as arbiters of Christian Europe and were consistently keen to foster peace among the Catholic powers. Numerous attempts at mediation had been made throughout the war, with varying degrees of success. The ongoing negotiations that led to the 1373 treaty were part of this long tradition of papal-led peace efforts.
The Role of the Avignon Papacy
The Avignon Papacy, while politically aligned with France due to its geographical proximity and French influence, would still strive for a semblance of neutrality in its mediation efforts. However, the perception of French favoring could not always be entirely dispelled.
Papal Legates and Their Mandates
Specific papal legates were appointed to carry messages and convene meetings between the English and French delegations. Their mandates typically involved proposing terms for a truce, exchanging prisoners, and exploring possibilities for a more permanent settlement.
Initial English Demands
England’s negotiators likely sought to solidify their territorial claims, particularly in Gascony and Ponthieu, and to secure recognition of Edward III’s claim to the French throne, or at least sufficient authority to grant him significant leverage. They would also have been concerned with the financial implications of the war.
French Counter-Proposals and Strategic Objectives
France, under Charles V’s guidance, would have been primarily interested in the restitution of occupied territories and the reaffirmation of French sovereignty. They would have been less inclined to grant concessions that weakened their territorial integrity or legitimized Edward III’s dynastic claims.
Challenges and Impasses in Negotiation
The negotiations were far from smooth. The deeply entrenched animosities, the competing territorial claims, and the inherent mistrust between the two crowns led to numerous stumbling blocks.
The Question of Sovereignty
The fundamental issue of sovereignty remained a persistent obstacle. England’s assertion of a right to the French throne was an existential threat to the French monarchy, making full capitulation on this point impossible for French negotiators.
Territorial Disputes and Boundaries
The precise demarcation of territories and the status of existing English-held strongholds in France were also highly contentious. France sought to regain all lost territories, while England aimed to maintain any gains that were strategically or economically valuable.
The Fate of Allied States and Dependencies
The treaty also had to consider the complex web of alliances and dependencies that existed. The status of Aquitaine, Flanders, and other regions with existing allegiances to either the English or French crown presented further diplomatic challenges.
Key Provisions of the Treaty of London

While not a comprehensive peace treaty, the Treaty of London of 1373 outlined several crucial agreements, primarily focusing on a truce and the exchange of certain concessions. Its details, as documented in contemporary chronicles and diplomatic correspondence, reveal a pragmatic approach to de-escalation rather than a profound reconciliation.
The Truce and Its Duration
The most immediate and significant provision of the treaty was the establishment of a truce between England and France. This truce provided a temporary cessation of hostilities, allowing both sides to regroup and reassess their strategic positions.
The Nature of the Truce
This was not an indefinite peace but a defined period during which military operations were to cease. The exact length of the truce varied in its interpretation and enforcement, but its primary purpose was to provide a respite from the constant state of war.
Specific Articles Concerning Ceasefire
The treaty would have contained specific articles detailing the terms of the ceasefire, including geographical boundaries where fighting was to stop and protocols for disengaging forces.
Implications for Border Regions
The truce would have had a direct impact on the border regions, where skirmishes and raids were common. It offered a period of relative calm for those living in these contested areas.
Territorial Arrangements and Border Demarcations
The treaty addressed, to some extent, the contentious issue of territory. While not resolving all disputes, it sought to establish a clearer understanding of existing holdings and potentially map out some zones of influence.
The Status of Gascony and Aquitaine
The Duchy of Aquitaine, and specifically Gascony, remained a focal point of these negotiations. The treaty likely clarified the administrative control and obligations within these territories, though fundamental sovereignty disputes persisted.
English Holdings and French Claims
The treaty would have attempted to define the extent of English holdings within Aquitaine and acknowledge the overarching French claim to the territory. This often led to complex arrangements regarding fealty and governance.
Other Territories and Border Fortifications
Beyond Gascony, other regions and strategic fortifications might have been mentioned. Agreements regarding their status, or the demilitarization of certain areas, could have been part of the treaty’s provisions.
Prisoner Exchanges and Economic Considerations
The cessation of hostilities also opened avenues for resolving issues related to captured individuals and the economic impact of the war.
Release of Prisoners of War
Protocols for the exchange of prisoners, often involving significant ransoms, were usually a crucial component of such treaties. This allowed for the return of valuable individuals and a reduction in the financial burden of their upkeep.
Ransoms and Financial Settlements
The treaty would have detailed the terms for ransoming prisoners, often involving complex financial settlements that impacted the treasuries of both kingdoms.
Impact on Trade and Commerce
A truce offered the potential for the resumption of some limited trade and commerce between the warring nations, or at least in regions not directly involved in recent conflict. However, deep-seated mistrust could limit the extent of this economic recovery.
The Treaty’s Immediate Impact and Limitations

The Treaty of London, while a diplomatic achievement of sorts, was ultimately a pragmatic instrument with significant limitations. Its impact was localized and temporal, and it did little to resolve the fundamental issues that fueled the Hundred Years’ War.
A Brief Respite, Not Lasting Peace
The treaty’s primary success was in providing a temporary cessation of fighting. It was a breathing space, allowing both sides to recover and rearm, rather than a definitive end to the conflict.
Renewed Hostilities and Breaches of Truce
The truce was often fragile and subject to breaches. Local commanders, driven by their own agendas or opportunities, could easily reignite hostilities, undermining the broader diplomatic aims of the crowns.
Skirmishes and Border Incidents
Despite the truce, minor skirmishes and border incidents continued to occur, often exacerbated by the presence of mercenary companies and the lingering animosities.
Shifting Alliances and International Dynamics
The international landscape remained fluid. The treaty did not inherently alter the complex web of alliances that characterized medieval Europe. Shifts in power among other European states could influence the willingness of England or France to adhere to the terms of the treaty.
The Strategic Advantages of the Truce
For both England and France, the treaty offered distinct strategic advantages that went beyond mere peace.
England: Consolidating Gains and Reorganizing Forces
For Edward III, the truce provided an opportunity to consolidate his existing territorial gains in France, strengthen his garrisons, and perhaps replenish his depleted treasury. It allowed for a period of relative stability from which to launch future campaigns or negotiate from a stronger position.
Financial Relief and Resource Management
The cessation of active warfare meant a reduction in immediate military expenditure, allowing the English crown to manage its finances more effectively and potentially reinvest in other areas.
Manpower and Reinforcement
The truce allowed for the recruitment and training of new troops, as well as the reinforcement of existing garrisons, preparing England for future engagements.
France: Internal Consolidation and Military Buildup
Charles V, who had been steadily rebuilding French strength, could use the truce to further solidify his internal authority, strengthen his administration, and continue his military reforms without the immediate threat of English invasion.
Strengthening the Royal Administration
The period of relative peace allowed Charles V to focus on administrative reforms, to collect taxes more efficiently, and to centralize royal power within France.
Continued Military Modernization
France could use this time to further develop its professional army, acquire new weaponry, and refine its siege warfare tactics, preparing for a more sustained offensive against English holdings.
The Treaty’s Limited Impact on the War’s Trajectory
Ultimately, the Treaty of London of 1373 did not fundamentally alter the course of the Hundred Years’ War. The underlying causes of the conflict remained unresolved, and the ambitions of both monarchs continued to clash.
The Unresolved Dynastic Claim
Edward III’s claim to the French throne, the original casus belli, was never truly addressed by the treaty. This fundamental dispute would continue to fuel the war for decades to come.
The Underlying Economic and Political Rivalries
The economic rivalries, particularly concerning Flanders, and the broader political aspirations of both England and France remained potent forces that the treaty could not pacify.
