To a modern observer, the medieval world often appears as a brutal tableau of endemic violence and lawless chaos. We imagine mail-clad knights settling disputes at the point of a lance, their ambitions unchecked by any recognisable legal authority. It is a tempting picture, one of thrilling anarchy. Yet, it is profoundly misleading. The medieval aristocratic system of power was not a lawless free-for-all; it was a different kind of order, one founded not on abstract statutes and state monopoly of force, but on a complex and constantly shifting balance of power, personal loyalties, and the accepted use of coercion as a political tool. This was a system where violence, or the threat of it, was a legitimate instrument of negotiation, a grammar of power understood by all who wielded it.
Nowhere can we see the contours of this order more clearly than in the history of a county like Lincolnshire. From the trauma of the Norman Conquest to the dynastic clashes of the Wars of the Roses, the fields and fortunes of this region, including those of the small but representative Barony of Brattleby, were shaped by this uniquely medieval logic. This was not a failure of order, but its very expression.
The Norman Imposition: A New Foundation of Power
The Norman Conquest of 1066 was the ultimate expression of power creating a new reality. William the Conqueror’s victory was not merely a change of king; it was a violent revolution in land tenure and social structure. The old Anglo-Saxon and Anglo-Danish aristocracy of Lincolnshire was systematically dispossessed, its lands parcelled out to the new Norman elite as a reward for service and a guarantee of future loyalty.
The Domesday Book of 1086, that formidable and dispassionate survey, is the foundational text of this new order. It is an auditor’s report of a kingdom seized by force. For the manor of Brattleby ("Bratelbi" in the survey), the entry is terse but profoundly eloquent. Before the Conquest, its lands were held by Ulf of Thorney, abbot of the great Fenland monastery. By 1086, it was held by one of the most powerful of the new Norman magnates in the region: Gilbert de Gant (or Ghent).
Gilbert’s acquisition was not the result of a legal transaction in any modern sense. It was the spoils of war, granted by a king who had won his crown by the sword. His vast new barony, centred on Folkingham, comprised over 170 manors, the bulk of them in Lincolnshire. This grant was not an outright gift. It established a deeply personal and reciprocal bond. In return for the land and its revenues, Gilbert owed the King servitium debitum—the ‘owed service’ of a specified number of knights for the royal army. The entire realm was now a web of such relationships, a pyramid of power with the king at its apex, its stability dependent on his ability to command the loyalty and military might of tenants-in-chief like Gilbert de Gant. The land itself was the currency of power, and the obligation to defend it, and the king’s peace, was its primary condition. This was a system where law flowed from the point of a sword and was guaranteed by the chain-mail hauberk.
The Anarchy: When the Centre Cannot Hold
The structural integrity of this power system rested on a single, strong royal authority. When that authority fractured, the delicate balance collapsed, and the magnates were free to pursue their own interests through the same means the monarchy used: organised force. The period known as ‘the Anarchy’ (1135–1153), the destructive civil war between King Stephen and the Empress Matilda, provides the most visceral example of this principle in action.
With two competing claimants to the throne, the barons of England were faced with a perilous choice. Allegiance was a gamble. Supporting the wrong side could mean forfeiture of lands and titles. For many, the safest—and most profitable—course of action was to exploit the royal weakness for their own aggrandisement. Lincolnshire, a strategic nexus between the north and south of England, became a primary theatre of this conflict.
The key players here were the formidable half-brothers, Ranulf de Gernon, Earl of Chester, and William de Roumare, Earl of Lincoln. Their ambitions were centred on securing dominance over Lincolnshire, particularly the strategic prize of Lincoln Castle. In late 1140, they seized the castle by a ruse. King Stephen, enraged by this act of defiance, marched north and laid siege to it. This prompted Ranulf to forge an alliance with Matilda’s most powerful supporter, her illegitimate half-brother Robert, Earl of Gloucester.
On 2 February 1141, their combined forces met Stephen’s army outside the city walls in the First Battle of Lincoln. The chronicler Orderic Vitalis provides a vivid account: loyalist knights dismounting to fight on foot around their king while the Welsh mercenaries in Ranulf’s army broke the royalist wing. Stephen, "a man of great strength and valour," fought on with his battle-axe and then his sword until both shattered. Deserted and overwhelmed, he was captured.
The king’s capture did not end the war; it simply shifted the balance of power. Matilda’s brief and arrogant ascendancy was short-lived, and the conflict ground on for another decade. During this time, magnates across the country built what later chroniclers called "adulterine" castles—private, unlicensed fortifications from which they could dominate the surrounding landscape, extract "protection" money (a practice known as maletolt), and wage private wars. The Gesta Stephani laments that "every powerful man made his own castles… and they filled the land full of castles. They sorely burdened the unhappy people of the country with forced labour on the castles." This was not random brigandage. It was a rational, if brutal, response to a power vacuum. With no undisputed king to enforce peace, the great lords became the de facto law in their own territories, their power limited only by that of their neighbours.
The Great Charter: Formalising the Rules of Conflict
The accession of Henry II in 1154 marked a profound reaction against the chaos of the Anarchy. The new Angevin king was a man of immense energy and legalistic genius. He systematically dismantled the adulterine castles, restored royal authority, and, crucially, expanded the scope and reach of royal justice. Through reforms like the Assize of Clarendon (1166) and the development of the Common Law, he sought to make the king’s court the ultimate arbiter of disputes, supplanting the private jurisdictions of his barons.
His son, King John, however, stretched these royal prerogatives to their breaking point. Through arbitrary taxation, vindictive judgements, and the cynical exploitation of his feudal rights, he alienated a powerful faction of the aristocracy. The result was not a descent into Anarchy-style chaos, but a far more sophisticated response: an attempt to codify the limits of royal power and formalise the barons’ right to resist. This was Magna Carta.
While celebrated today as a foundation stone of liberty, the Great Charter of 1215 was, in its time, a deeply conservative and pragmatic document. It was a feudal contract, a list of grievances and demands drawn up by men of power to protect their interests from a king who had overstepped the accepted bounds of authority. Many of its 63 clauses deal with specific feudal customs—inheritance taxes, wardship, and the rights of widows.
Lincolnshire was at the heart of this baronial rebellion. The "Northern" barons who drove the opposition to John included many with vast estates in the county. Crucially, one of the 25 barons elected to enforce the charter was Gilbert de Gant, a direct descendant of the Domesday lord of Brattleby. Other key figures with strong Lincolnshire ties included Simon of Kyme and William d'Aubigny, lord of Belvoir Castle just across the border. It is no coincidence that Lincoln Cathedral is the proud home of one of only four surviving original exemplars of the 1215 Magna Carta, brought back to the diocese by its bishop, Hugh of Wells.
The charter’s most radical and revealing provision was Clause 61, the "security clause." This text is the ultimate codification of the medieval order of force. It established a committee of 25 barons who were empowered, if the king violated the terms of the charter, "to distrain and distress us in every way they can, namely, by seizing castles, lands, possessions, and in such other ways as they can, saving our person and the persons of our queen and our children."
This was not a declaration of illegal rebellion; it was contractually sanctioned warfare. It gave the barons a "legal" right to wage war on their own king. It perfectly encapsulates the medieval worldview: when negotiation failed and the established political relationship broke down, force was the final, and legitimate, court of appeal. The conflict that followed the charter's repudiation by John and the Pope, known as the First Barons' War, culminated once more on the streets of Lincoln. The Second Battle of Lincoln (20 May 1217), a decisive victory for the loyalists of the young King Henry III led by the legendary William Marshal, effectively ended the French invasion and secured the future of the Plantagenet dynasty—and the reissued Magna Carta.
The End of an Era: Bastard Feudalism and the Wars of the Roses
The centuries that followed saw the continued growth of royal law and a centralising state. Yet the underlying principles of the order of force did not vanish; they mutated. By the 15th century, the classic feudal relationship based on land for military service had been largely replaced by what historians have termed "bastard feudalism."
Great magnates like the dukes of York, Lancaster, Somerset, and Warwick maintained their power not primarily through tenants, but through vast networks of "retained" gentry and soldiers. These men were bound to their lord by indenture (a written contract), receiving annual fees, robes (livery), and the promise of "good lordship"—the lord’s influence in legal disputes and pursuit of office (maintenance). In return, they owed him military and political support. This created powerful, semi-private armies that were loyal to a magnate first and the king second.
When the authority of the crown once again faltered during the disastrous reign of the mentally fragile Henry VI, these magnate affinities provided the military muscle for the dynastic conflict known as the Wars of the Roses (c. 1455–1487). The dispute between the rival houses of Lancaster and York was fought by armies that were essentially coalitions of these private retinues.
Lincolnshire again found itself drawn into the maelstrom. In March 1470, a local dispute instigated by the Welles family spiralled into a major rebellion against the Yorkist king, Edward IV. The uprising was secretly incited by the ambitious Richard Neville, Earl of Warwick ("the Kingmaker"), and the king’s own brother, George, Duke of Clarence, who were plotting to overthrow Edward. Sir Robert Welles raised the men of Lincolnshire under the cry of "King Henry!" and marched to confront the royal army.
The resulting clash, fought near Empingham in Rutland on 12 March 1470, is known to history as the Battle of Losecoat Field. Upon the arrival of the king’s formidable army, and after a preliminary cannonade, the rebel force broke and fled in panic, supposedly shedding their liveried coats (which identified them as retainers of Warwick and Clarence) to avoid being identified as traitors. The name, whether apocryphal or not, vividly captures the reality of a war fought not by a national army but by affinities identified by their lord's badge. Edward IV crushed the rebellion, executed its leaders, and the immediate threat from Warwick and Clarence was contained, albeit temporarily.
This conflict demonstrates how, even in the late medieval period with its more developed legal and administrative state, the ability to muster private force remained a central element of high politics. The greatest lords did not petition the king; they negotiated with him from a position of armed strength. The system was still, at its core, an order of force.
Conclusion: A Vanishing World
The world in which the lords of Brattleby and their peers operated was governed by a logic of power profoundly different from our own. To dismiss their conflicts as mere thuggery or lawlessness is to misunderstand the very fabric of their society. From the brutal clarity of the Norman settlement to the contractually sanctioned warfare of Magna Carta and the affinity-based armies of the 15th century, force was an integral, accepted, and often necessary component of the political order.
This system was only truly dismantled by the Tudors. Henry VII’s determined suppression of private retaining and livery, and the establishment of a powerful central government with a near-monopoly on legitimate violence, marked the transition from the medieval to the modern state. The silent fields of Brattleby, which had passed from a Saxon abbot to a Norman conqueror, whose descendant challenged King John, and whose county neighbours rose in rebellion against Edward IV, would henceforth see their destinies determined not by the local balance of power, but by the writ of a distant and unchallengeable crown. The old order of force had finally given way to the new order of law.
