Treaty Of York

The year 1237, a mere blink in the grand, tedious march of history, saw the formalisation of an agreement that, against all odds, proved rather durable. Dubbed the Treaty of York – or, if you prefer its full, ponderous Latin title, Scriptum cirographatum inter Henricum Regem Anglie et Alexandrum Regem Scocie de comitatu Northumbrie Cumbrie et Westmerland factum coram Ottone Legato – this document, signed with considerable fanfare and likely even more underlying suspicion, cemented a border that has, for the most part, stubbornly refused to budge since.

This pivotal, if often overlooked, accord was struck in the city of York on the 25th of September in the year 1237. The principal signatories, as one might expect from such a geographically specific arrangement, were Henry III of England and Alexander II of Scotland . The primary, and arguably most lasting, consequence of this treaty was the definitive affirmation of English sovereignty over the strategically significant northern territories of Northumberland , which at that historical juncture also encompassed the nascent County Durham , alongside Cumberland , and Westmorland . This declaration drew a line in the proverbial sand, establishing the Anglo-Scottish border in a configuration that has endured, with only minor, almost negligible, modifications concerning the perpetually contentious Debatable Lands and the eternally contested Berwick-upon-Tweed , into the modern era. Beyond the monumental task of defining a national boundary, the treaty meticulously elucidated the future status of various feudal properties and attempted to resolve a myriad of other simmering disputes between the two reigning monarchs. Historically, and with a certain weary finality, it marked the effective cessation of the Kingdom of Scotland ’s long-standing, and ultimately fruitless, ambition to expand its territorial dominion southward into the English realm. One might say it was the moment Scotland decided, or was forced, to look inward, or perhaps just to the east and west, for its future endeavours.

Historical Context and Papal Intervention

This particular treaty, while significant in its outcome, was hardly an isolated incident. It existed as merely one in a long, convoluted series of agreements and uneasy truces that characterised the perpetually fluctuating relationship between the English and Scottish crowns. Such was the volatile nature of medieval diplomacy; one treaty simply paved the way for the next, often to address the very issues the previous one failed to resolve.

Adding a layer of papal gravitas, or perhaps just an additional pair of critical eyes, to the proceedings was the presence of the papal legate , Otho of Tonengo . Otho was already ensconced in the Kingdom of England at Henry III ’s specific request, preparing for a synod scheduled to convene in London in November 1237. Henry, ever the pragmatist, or perhaps merely unwilling to miss an opportunity for ecclesiastical endorsement, had the foresight to inform Otho in advance of the September meeting at York . Consequently, Otho attended, lending a veneer of impartial authority to the negotiations – or at least, that was the intention. His presence was duly noted by the contemporary chronicler Matthew Paris , a man whose historical accounts rarely lacked for opinion. Paris, with his characteristic flair for disparagement, managed to cast both Alexander II and Otho in a rather unflattering light, proving that even in the 13th century, chroniclers understood the value of a good critical review.

The Agreement

The relationship between Henry III and Alexander II was, by all accounts, a tangled web of political expediency and familial ties, a common enough arrangement among medieval royalty. After all, what better way to complicate foreign policy than to marry off your relatives? Alexander, for instance, was married to Henry’s sister, Joan , a union that theoretically should have fostered harmony, though history suggests otherwise. Conversely, Alexander’s own sister, Margaret , had been wed to Hubert de Burgh , a figure of considerable influence and a former regent during Henry’s minority. These matrimonial alliances, designed to interweave royal houses and prevent conflict, often merely provided new avenues for grievances.

It was against this backdrop of interwoven relationships and persistent border disputes that Henry III formally advised the papal legate Otho on 13 August 1237 of his intention to meet Alexander II at York to “treat of peace.” A rather optimistic phrasing, perhaps, given the history. The ensuing negotiations culminated in the agreement signed on 25 September, explicitly stating its scope as “respecting all claims, or competent to, the latter, up to Friday next before Michaelmas A.D. 1237.” This precise temporal limitation underscored the pragmatic, often piecemeal, nature of such diplomatic efforts, acknowledging that future disputes were not only possible but probable.

The full, rather impressive, Latin title of the agreement, Scriptum cirographatum inter Henricum Regem Anglie et Alexandrum Regem Scocie de comitatu Northumbrie Cumbrie et Westmerland factum coram Ottone Legato, translates roughly to “Chirograph written between Henry King of England and Alexander King of Scotland concerning the counties of Northumberland, Cumberland, and Westmorland, done in the presence of Legate Otho.” A chirograph was a medieval legal document, often written in duplicate or triplicate on a single sheet of parchment, then cut apart with an irregular, often wavy, line. Each party would receive a piece, and the authenticity could be verified by matching the cuts, a quaintly analogue security measure for a rather serious matter of state.

The specific, and rather crucial, particulars of this agreement were as follows, each point a carefully negotiated concession or demand:

• The King of Scotland , Alexander II , formally issued a quitclaim – essentially a relinquishment of claim – to the King of England regarding his hereditary rights to the contested counties of Northumberland , Cumberland , and Westmorland . This was the bedrock of the treaty, the formal abandonment of Scottish claims to these coveted northern territories. Furthermore, Alexander also quitclaimed a substantial sum of 15,000 marks of silver. This was no trifling amount; it represented a payment made by King William I of Scotland (Alexander’s father) to King John of England for certain conventions, or agreements, which, predictably, John had failed to uphold. This particular clause served to clear a long-standing financial and historical grievance, wiping the slate clean of a debt that was as much about honour as it was about currency. Lastly, the Scottish king released Henry from any prior agreements concerning potential marriages between Henry and his brother Richard, 1st Earl of Cornwall , and Alexander’s sisters, Margaret, Isabella, and Marjory. Such marital arrangements were frequently used as political bargaining chips, and their dissolution here signified a re-evaluation of dynastic alliances.
• In a gesture of reciprocal, if somewhat calculated, magnanimity, the King of England , Henry III , granted the King of Scotland certain specific lands situated within Northumberland and Cumberland . These lands were to be held by Alexander and his successor kings of Scotland in feudal tenure, a common landholding system of the era. Crucially, these grants came with particular rights that explicitly exempted them from many of the customary obligations inherent in typical feudal relationships. For instance, the Scottish Steward was granted the authority to sit in Justice concerning certain issues that might arise within these granted territories. Moreover, these rights and holdings were stipulated as hereditary to the Scottish king’s heirs, and significantly, the King of Scotland was explicitly exempted from being answerable to an English court of law in any legal suit pertaining to these specific lands. This complex arrangement allowed the Scottish crown to retain a foothold and a degree of judicial autonomy within what was unequivocally English territory, a delicate balance designed to appease without truly conceding sovereignty.
• The King of Scotland formally rendered his homage and fealty – de praedictis terris – for these aforementioned lands. This act, a cornerstone of feudal relationships, acknowledged Henry as his liege lord for these specific holdings, even as it underscored his independence as a sovereign monarch elsewhere. It was a careful distinction, laden with potential for future misinterpretation.
• Finally, both kings committed to respecting any previous written agreements that did not conflict with the terms of this new treaty. Any charters found regarding the aforementioned counties that were now definitively English were to be returned to the King of England . A tidy administrative detail, ensuring all paperwork aligned with the new reality.

Despite its clear historical impact in drawing a lasting border, the Treaty of York has, rather ironically, been met with a surprising degree of indifference from subsequent historians. It seems that a definitive resolution, however hard-won, lacks the dramatic appeal of ongoing conflict. Many historical accounts mention it only in passing, if at all, which, one might argue, is a rather fitting commentary on the human tendency to focus on the noise rather than the quiet, foundational shifts. For example, William Stubbs entirely omits it from his comprehensive Constitutional History of England, a rather glaring oversight for a document that shaped a nation’s geography. Similarly, David Hume in his multi-volume History of England found no occasion to reference it. William Forbes Skene ’s Celtic Scotland refers to it merely as an agreement within his background discussion leading into the reign of Alexander III of Scotland , implying its significance was more preparatory than epochal. John Hill Burton ’s History of Scotland acknowledges that land claims were discussed in 1237 and offers a brief description of some of these claims but, again, makes no explicit reference to the existence of a formal agreement or treaty. It was only James Hill Ramsay ’s Dawn of the Constitution that offered a more extensive discussion of the agreement’s terms, though even Ramsay refrained from bestowing upon it any particular prominence. One must wonder if the clarity it brought was simply too mundane for the chroniclers of chaos.

The Account of Matthew Paris

The treaty’s narrative is, however, spiced up considerably by the vivid, and often biased, accounts of the chronicler Matthew Paris (c. 1200–1259). Paris, known less for dispassionate objectivity and more for his robust rhetorical passion and thinly veiled invectives against those who failed to meet his exacting standards, offers a rather colourful perspective on the key players.

Paris, with a pen sharpened by apparent disapproval, paints a distinctly negative portrait of the Papal legate Otho . He describes Otho as a man of shifting character: weak and timid when confronted with true strength, yet insufferably overbearing in his exercise of power over those he perceived as lesser. And, of course, no villain of Paris’s pen would be complete without a healthy dose of avarice, with Otho depicted as relentlessly accumulating vast sums of money – a detail that likely resonated with many contemporary readers weary of ecclesiastical taxation.

Turning his gaze to the monarchs, Paris vividly recounts what he perceived as a “mutual hatred” between Alexander II and Henry III in 1236, a year prior to the treaty. He even claims that Alexander, in a fit of royal pique, threatened to invade England. Such declarations, whether genuine threats or mere diplomatic bluster, certainly provided excellent fodder for Paris’s dramatic narratives.

When detailing the 1237 meeting at York , Paris presents it as a direct result of invitations extended by both Henry III and Otho to the Scottish king. The chronicler then delights in recounting Alexander’s purported reaction when Otho expressed an interest in visiting Scotland. Alexander, according to Paris, defiantly declared that no legate had ever set foot in Scotland and that he, Alexander, would certainly not permit it. Further, the Scottish king allegedly issued a veiled threat, warning Otho that should he dare to enter Scotland, he should “take care that harm does not befall him.” A charming invitation, indeed. Paris, never one to let a good story lie, later elaborates on this in his 1239 entry, stating that as Otho was finally preparing to depart for Scotland, Alexander’s initial hostility at the prospect of Otho’s visit in 1237 had been so intense that a specific written agreement had to be meticulously drawn up, solely concerning the terms and conditions of Otho’s eventual visit. One can almost hear Emma’s dry chuckle at the sheer bureaucratic absurdity of it all.
