IBDP History Exam Question

 

  EXAMPLE I

 Alfred of Wessex and Frederick II of Hohenstaufen stand as two figures whose reigns illustrate contrasting yet complementary approaches to governance in the medieval period. Alfred, born circa 849 and reigning from 871 until his death in 899, inherited a fragmented Anglo-Saxon polity beset by Viking incursions and internal discord. His success rested on reforms intended to secure his realm against external aggressors and to foster a sense of cultural unity. By instituting legal reform, reordering the military levy and fortifying his territories through the construction of burhs, Alfred demonstrated an ability to adapt traditional structures to meet emergent challenges. His extensive translations of Latin texts into Old English and his promotion of learning not only preserved religious and cultural texts but also seeded the intellectual revival that would later characterise England. In parallel, Frederick II, born in 1194 and reigning as King of Sicily and Holy Roman Emperor from 1220 until his death in 1250, confronted a diverse range of challenges across a vast and multiethnic domain. His rule was marked by innovative legal codifications, notably the Constitutions of Melfi in 1231, and by an administrative system that emphasised merit and efficiency over feudal privilege. Frederick’s realm, which encompassed regions with distinct cultural and religious identities, was united through a series of reforms that standardised law, administration and fiscal policies. Both leaders, though operating in different geographical and cultural contexts, undertook extensive projects aimed at consolidating power from within rather than relying solely on military conquest. Their success, however, invites critical evaluation on the basis of political, economic, cultural and diplomatic outcomes. David Heath, Head of the Humanities Department at the Bavarian International School, contends that Alfred’s reforms provided the foundation for a future unified English state, while his analyses of Frederick’s measures underscore the innovative nature of constitutional governance in Sicily. The comparative evaluation of these two reigns demands an exploration of their administrative ingenuity, the economic vitality they engendered and the skilful use of diplomacy and military prudence to safeguard their achievements. Although Alfred’s victories over the Vikings and the subsequent stability of Wessex stand as enduring testaments to his pragmatic reforms, his reliance on martial resistance was tempered by his vision for cultural and educational renewal. Conversely, Frederick’s reign, while frequently challenged by conflicts with the papacy and internal aristocratic rivalries, exhibited a determination to employ legal and administrative modernisation as vehicles for long-term consolidation. This essay examines the extent to which the rule of Alfred and Frederick can be regarded as successful by analysing the transformative impact of their political and administrative reforms, the economic and cultural innovations they introduced, and the diplomatic as well as military measures they employed to secure their domains. Their achievements and limitations are scrutinised through the lens of recorded events and the evaluations of Heath, whose research asserts that both rulers, in different ways, laid the groundwork for modern statecraft. The interplay of stability, legal coherence, and cultural revival in their reigns offers a rich field for understanding medieval success. Both leaders navigated complex social hierarchies and external threats to create regimes that, while not without flaws, contributed fundamentally to the evolution of governance in Europe. Their legacy, measured through the continuity of legal systems and the endurance of administrative practices, continues to provoke debate regarding the criteria that define successful rule in medieval contexts.

Alfred’s reign in Wessex exhibited a commitment to transforming a society beleaguered by intermittent Viking invasions into one possessing the tools for coherent administration and long‐term stability. He instituted comprehensive military reforms by reorganising the fyrd, a system whereby local freemen were compelled to serve as soldiers, and by ordering the construction of fortified settlements known as burhs. These burhs, established from the mid‐870s onwards, served to protect agricultural communities and trade routes alike, and records indicate that by 886, more than 30 such fortifications were operational across the kingdom. His legal reforms, detailed in his revised law codes, redefined the administration of justice by codifying traditional customs and introducing standards for compensation that alleviated tension between freemen and the aristocracy. The establishment of a system of writs and regular judicial sessions contributed to the gradual transition from localised, arbitrary rule towards a more centralised form of governance. Heath argues that Alfred’s legislative and administrative endeavours provided a model of pragmatic statecraft that balanced martial defences with internal cohesion. His military successes, notably the celebrated victory at the Battle of Edington in 878, not only curtailed the Viking threat but also provided him with the political capital to implement reforms. In the aftermath of this victory, Alfred enhanced the structure of his government by introducing measures designed to boost educational standards; he initiated the translation of significant religious and philosophical works from Latin into Old English, thereby ensuring that his people could benefit from the intellectual heritage of the Latin world. This focus on education and literacy fostered a cultural unity that was instrumental in rallying support for his reforms. The reorganisation of the Church within his realm further contributed to the consolidation of royal authority, as ecclesiastical figures were co-opted into the administrative framework, thereby rooting the authority of the crown in both secular and sacred institutions. In transforming the military apparatus, codifying legal traditions and fostering a renaissance of learning, Alfred created a resilient state structure capable of enduring external shocks. His reforms in coinage, exemplified by the introduction of a standardised currency system, stimulated local trade and enhanced economic stability. Each of these measures was implemented alongside a careful balancing of local traditions and innovative governance techniques. The transformation of a fractious and vulnerable society into one characterised by administrative order and cultural continuity is evident from contemporary chronicles, which describe a period of revitalisation in the second half of his reign. Heath’s perspective on these developments highlights that Alfred’s accomplishments were not isolated successes; rather, they form an interconnected web of reforms that collectively redefined kingship in Anglo-Saxon England. The utilisation of existing feudal structures, reformed to meet the challenges of his time, underscores Alfred’s strategic acumen. His reliance on locally elected officials and the decentralisation of fiscal responsibilities paved the way for the emergence of regional governance models that would later be integral to a unified English state. Furthermore, his efforts to codify laws contributed to a reduction in localised disputes and a more predictable system of justice, thus enhancing the legitimacy of his rule. This period witnessed a marked improvement in public order, as evidenced by the reduction in recorded instances of feuding and the consistent application of new legal standards. Alfred’s ability to integrate military, legal and educational reforms into a coherent strategy reflects a level of statecraft rarely matched in his era. His administration managed to secure the loyalty of diverse social strata, from the peasantry to the nobility, through an emphasis on fairness and continuity. The long‐term success of his reign is underscored by the survival of many of his reforms in later centuries, a testament to his forward‐thinking approach to governance. The cumulative impact of these policies, as assessed by Heath, affirms that Alfred’s rule was fundamentally successful in creating a resilient and cohesive society, despite the perennial threat of external aggression. His legacy demonstrates that in times of crisis, the establishment of order through measured reforms can be as decisive as martial prowess. The enduring stability of Wessex, ultimately forming the nucleus of a future nation, stands as evidence of the lasting value of his political and administrative initiatives.

Frederick II’s approach to governance in his vast and culturally diverse domains transformed the traditional model of medieval rule through a series of innovative economic and cultural policies. His reign, which spanned the early 13th century until his death in 1250, was characterised by a deliberate attempt to centralise authority not solely through martial force but by cultivating economic stability and stimulating cultural exchange. The promulgation of the Constitutions of Melfi in 1231 established a legal framework that sought to guide public life in Sicily, standardising administrative procedures and reinforcing the supremacy of the crown over feudal lords. Heath observes that these reforms signalled a shift from a system reliant on warfare and personal loyalty to one structured around written laws and bureaucracy. The deliberate codification of legal principles reduced the scope for arbitrary justice and curtailed the traditional privileges of the local nobility, thereby creating a more equitable system of governance. Fiscal innovations under Frederick II involved the streamlining of revenue collection and the reorganisation of taxation, measures that are documented in surviving fiscal records to have boosted royal income significantly. His reforms in coinage and the regulation of trade ensured that commerce flourished across his territories, stimulating both local and international markets. The improvement in economic performance is evidenced by increased urban growth and the expansion of market towns, which formed the backbone of a burgeoning middle class. In cultivating economic prosperity, Frederick not only secured the resources necessary to maintain a competent administration but also enhanced the legitimacy of his rule among merchant communities and urban elites. His patronage of learning and the arts contributed to the construction of a vibrant cultural milieu in his court at Palermo, which attracted scholars, poets and scientists from across the Mediterranean. By fostering an environment in which ideas could circulate freely, he encouraged the integration of diverse intellectual traditions, including influences from Arab, Byzantine and Latin cultures. Heath maintains that this cultural pluralism was central to Frederick’s success, as it positioned his court as a centre of enlightenment and progress. The promotion of scholarly exchanges and the establishment of institutions dedicated to scientific and philosophical inquiry facilitated a transmission of knowledge that extended well beyond his reign. Artisans and intellectuals were supported through royal patronage, and the production of illuminated manuscripts and works on natural philosophy served as tangible evidence of a sophisticated state culture. In addition to cultural patronage, Frederick II invested in public infrastructure, commissioning the repair of roads and the establishment of regulated marketplaces that further integrated his realm. His innovative approach to governance also involved a pragmatic diplomacy that enabled him to negotiate enduring treaties with various European powers and even the papacy. Despite occasional conflicts with ecclesiastical authorities, his ability to balance the demands of different stakeholders within his administration underscored a nuanced and flexible approach to statecraft. The synthesis of economic innovation and cultural dynamism under his rule is further evidenced by detailed administrative records, which reveal a systematic approach to modernising fiscal and legal systems. The creation of a professional bureaucracy, staffed by officials chosen for their expertise rather than noble birth, marked a departure from traditional feudal practices and paved the way for more efficient governance. This shift towards meritocracy not only increased the effectiveness of his administration but also fostered an enduring sense of loyalty among his subjects. Heath’s evaluation of Frederick’s economic and cultural policies asserts that his reign was instrumental in shaping a modern administrative state, one in which prosperity and cultural vibrancy were interdependent. The union of fiscal responsibility and artistic patronage enhanced the overall stability of his realm, allowing him to maintain order without recourse to continuous warfare. His reign, therefore, stands as a paradigmatic example of how economic revitalisation and cultural flourishing can serve as the foundations for sustained political success. The integration of economic policies with cultural investments, as implemented by Frederick, contributed to an environment in which innovation and tradition coexisted in a mutually reinforcing manner. This multifaceted approach to governance ensured that his rule was marked by both material prosperity and intellectual achievement, cementing his reputation as one of his era’s most progressive rulers.

Alfred and Frederick navigated the complexities of external threats and the demands of diplomatic engagement with varying degrees of success. Alfred’s martial endeavours, though accompanied by stringent reforms in governance, were underpinned by a strategic appreciation of diplomacy that helped secure alliances and negotiate truces with neighbouring kingdoms and Danish chieftains. His military campaigns, encapsulated by the decisive victory at Edington in 878, were complemented by a network of fortified burhs that served as both defensive strongholds and symbols of royal authority. The careful integration of martial and diplomatic measures allowed Alfred to consolidate control over his territories without imposing excessive costs on his people. Heath suggests that his ability to combine military victory with administrative reform and diplomatic initiative set the foundation for enduring stability. The legacy of these measures is evident in the gradual emergence of a unified English state that laid the groundwork for later national consolidation. In contrast, Frederick II employed a more calculated blend of diplomacy and measured military engagement to navigate the complexities of his multiethnic empire. His reign was marked by a series of negotiations with the papal court, as evidenced by the intermittent treaties that sought to resolve the long-standing conflicts between secular and spiritual authorities. Although his conduct occasionally provoked hostility from religious factions, his diplomatic finesse enabled him to maintain a degree of autonomy from the ecclesiastical establishment. Correspondence preserved from his reign reveals that Frederick’s diplomatic approach was characterised by a willingness to engage directly with adversaries, a tactic that minimised the need for protracted military campaigns. His skilful management of external relations extended to forging alliances with regional powers in southern Italy and North Africa, thereby creating a web of support that reinforced his internal reforms. The measured use of military force, when deployed, was conducted with great deliberation and was always ensconced within a broader framework of legal and administrative initiatives. Records of military expenditure and campaign logistics confirm that Frederick preferred negotiation to outright warfare, recognising that the long-term consolidation of his realm depended on the stability afforded by peaceful coexistence. Heath’s analysis posits that his judicious use of military power, integrated seamlessly with diplomatic and administrative strategies, exemplified a form of governance that sought to establish lasting order rather than temporary dominance. Both leaders, therefore, employed military measures not as ends in themselves but as components of a broader strategy that emphasised sustainable government. The evidence suggests that Alfred’s direct confrontations with raiding forces were balanced by his commitment to cultural and legal renewal, whereas Frederick’s occasional military actions were subsumed under his overarching policy of administrative and fiscal modernisation. Each ruler’s approach, though distinct in emphasis and execution, underscores an understanding that military success alone was insufficient to secure long-term stability. Their reliance on diplomacy to complement martial action highlights a strategic recognition of the limits of force, an insight that remains relevant in discussions of statecraft. Archival documents from both reigns attest to a pattern of measured responses to external threats, emphasising negotiation and compromise over unrestrained aggression. The sustained peace that followed these diplomatic engagements served to enhance the legitimacy of both rulers, as subjects were more likely to support regimes that demonstrated a capacity for restraint and strategic acumen. Heath asserts that the ability to blend military capability with soft power was key to the lasting impact of their rule. The combination of external defence, diplomatic negotiation and measured martial intervention produced outcomes that were observed to stabilise their respective realms. Alfred’s efforts in securing treaties with neighbouring territories and Frederick’s skilful balance between confrontation and conciliation converge to underscore a common principle in effective governance. This principle, drawn from the practical realities of their reigns, highlights that success in medieval rule relied not solely on battlefield victories but on the orchestration of complementary strategies that addressed both internal cohesion and external threat management. Their legacies, as recorded in contemporary chronicles and analysed by Heath, remain testament to the pragmatic integration of diplomacy and military prudence as fundamental components of successful rule.

In conclusion, both Alfred of Wessex and Frederick II of Hohenstaufen exemplify the multifaceted nature of medieval success. Their reigns demonstrate that effective rule required a synthesis of political, economic, cultural and military initiatives. Alfred transformed a vulnerable and fragmented society into one capable of withstanding relentless external pressures through the establishment of fortified settlements, comprehensive legal reforms and the revitalisation of learning. His legacy, replete with a unifying legal code and a reformed military structure, provided the fundamental infrastructure upon which a future nation would be built. Frederick II, operating within a context of cultural diversity and internal dissent, redefined governance by codifying laws, modernising fiscal policies and fostering a vibrant cultural environment that embraced intellectual exchange across borders. His innovative administrative reforms and balanced approach to diplomacy and military engagement secured stability in a realm that was both extensive and heterogenous. Critically, Heath’s evaluations affirm that each ruler, in confronting the challenges of their era, adopted strategies that transcended the mere use of force. Their reliance on measured reforms and institutional innovation, rather than the transient victories of warfare, enabled both leaders to leave a lasting imprint on the political landscape of medieval Europe. Despite the differing contexts in which they ruled, the success of their reigns can be gauged not only by the immediate consolidation of power but also by the durable impact their policies had on the evolution of modern statecraft. Their examples underscore that the legitimacy of rule in the medieval period was rooted in the capacity to integrate diverse strategies into a coherent system of governance, one that could secure internal unity and foster resilience in the face of external challenges.

 

EXAMPLE II

Evaluating the success of medieval rulers requires navigating a complex web of contemporary expectations, dynastic ambitions, territorial gains, administrative legacies, and indeed, posthumous reputations. Success in this era was rarely absolute and often contingent upon circumstances beyond an individual's control, including harvests, plagues, and the shifting allegiances of powerful nobles. Examining the reigns of Charlemagne, King of the Franks and Lombards and later Holy Roman Emperor, and Louis IX, King of France, provides fertile ground for such an assessment. Both rulers left indelible marks on European history, achieving significant accomplishments according to the metrics of their time and beyond. However, their paths to success, the nature of their achievements, and the sustainability of their projects differed considerably. Charlemagne’s reign is often seen as a pinnacle of early medieval state-building, characterised by vast military expansion and a conscious revival of imperial ideals in the West. Louis IX’s rule is frequently lauded for its moral authority, judicial reforms, and the consolidation of royal power within France through means that, while not entirely peaceful, placed a strong emphasis on justice and piety. By analysing the extent to which each monarch fulfilled their objectives, maintained stability, fostered development within their realms, and created lasting institutions or legacies, a nuanced understanding of their respective successes can be attained. This necessitates moving beyond hagiography or simplistic notions of medieval kingship to grapple with the practicalities and limitations of power in this period.

Charlemagne’s rule, spanning from 768 to 814, can be regarded as remarkably successful in terms of territorial expansion and the projection of Frankish power across Western Europe. Through relentless military campaigning, he dramatically enlarged the territories inherited from his father, Pepin the Short. The protracted and brutal wars against the Saxons, lasting from 772 until 804, ultimately resulted in their subjugation and forced conversion to Christianity, integrating a vast swathe of territory in present-day Germany into the Frankish realm. Campaigns in Italy led to the conquest of the Lombard Kingdom in 774, securing Charlemagne the Lombard crown and significantly expanding his influence on the Italian peninsula and his relationship with the Papacy. His interventions in Iberia, though meeting with setbacks such as the famous ambush detailed in the "Song of Roland", established the Spanish March around Barcelona as a buffer zone against Umayyad Hispania. To the east, the defeat of the Avars in the late 8th century not only neutralised a significant threat but also brought vast quantities of treasure into Frankish hands, further funding his ventures. By 800, his dominion stretched from the Pyrenees to the Elbe, from the North Sea to central Italy. This sheer scale of conquest, unmatched by any Western European ruler for centuries prior, undoubtedly constitutes a primary measure of his success in the eyes of many contemporaries and subsequent historians. His coronation as Emperor by Pope Leo III in Rome on Christmas Day 800, while debated in terms of its immediate impetus and Charlemagne’s own desires, represented a monumental ideological success, reviving the concept of a Roman Empire in the West and positioning Charlemagne as its divinely sanctioned head. This act profoundly shaped the political and religious landscape of Europe for centuries, creating a potent symbol of unity and Christian rulership. Collins argues that while the military achievements were significant, the long-term institutional impact is more complex. He suggests that the Carolingian Empire remained heavily reliant on personal loyalty to the ruler and the exploitation of conquered resources, rather than deeply rooted bureaucratic structures that could guarantee permanence. Evaluating this perspective, it highlights a crucial tension in assessing Charlemagne’s success: the difference between immediate achievements and enduring systemic change. While Charlemagne did implement administrative reforms, such as the use of *missi dominici* (royal envoys) to oversee local administration and ensure compliance with royal decrees, and fostered standardisation in coinage and script, the infrastructure of the state struggled to effectively govern such vast territories in the long term. The reliance on oaths of fealty and the distribution of land to secure service meant that central authority was always mediated through powerful regional magnates. His promotion of education and culture, often termed the Carolingian Renaissance, was another notable success. Bringing scholars like Alcuin of York to his court at Aachen, he initiated reforms in education, promoted the copying of classical and Christian texts in a more legible script (Carolingian minuscule), and encouraged the establishment of schools in monasteries and cathedrals. This had lasting benefits for literacy, learning, and the preservation of knowledge. Economically, efforts were made to standardise weights and measures, and the introduction of a new silver coinage system facilitated trade. However, the economy remained fundamentally agrarian, and the logistical challenges of managing such a large empire were immense.

Louis IX’s reign, from 1226 to 1270, presents a different model of successful medieval kingship, one less focused on dramatic territorial conquest and more on internal consolidation, judicial reform, and the personification of Christian ideals of monarchy. His reputation for piety and justice was so profound that he was canonised as Saint Louis in 1297, a rare achievement for a medieval ruler that significantly shaped perceptions of his success. One of his most significant successes lay in strengthening royal authority and institutions within France. He worked tirelessly to establish the king as the supreme dispenser of justice. The introduction of royal *enquĂȘtes*, inquiries conducted throughout the kingdom to address grievances against royal officials, demonstrated a commitment to fair governance and allowed the crown to intervene more directly at a local level, bypassing potentially corrupt or self-serving local lords. These investigations provided invaluable information about the state of the realm and reinforced the idea that the king was accessible and concerned with the welfare of all his subjects, irrespective of status. The extension of the right of appeal to royal courts further centralised judicial power. Louis placed great emphasis on due process, famously attempting to curtail judicial duels and promoting evidence-based justice. His personal involvement in dispensing justice, as mythologised in Joinville’s account of him holding court under an oak tree at Vincennes, cemented his image as a just king directly engaged with his people's needs. Le Goff argues that Louis IX meticulously constructed his image as the ideal Christian king, using piety and justice as powerful tools of statecraft. He suggests that Louis’s deep religiosity was genuine but also politically astute, allowing him to legitimise the expansion of royal power under a moral guise. Evaluating this, Le Goff does not dismiss Louis’s faith but rather highlights its functional role in his success. His piety resonated deeply with contemporary values, giving him a moral authority that few other monarchs possessed. This facilitated acceptance of increased royal intervention. Territorially, Louis IX’s reign was more about consolidation than aggressive expansion. The Treaty of Paris in 1259 with Henry III of England was a key success in this regard. Louis agreed to Henry holding Gascony as a fief of the French crown, while Henry renounced claims to Normandy, Anjou, and Poitou, territories lost under previous English kings. This treaty, though criticised by some French nobles for being too generous, brought a period of relative peace and formally acknowledged Capetian gains, stabilising the western borders of the kingdom. His administrative reforms further strengthened the machinery of government. The development of more specialised institutions within the royal court, such as the *Parlement* of Paris evolving into primarily a judicial body, and the increasing professionalism of royal administrators, many trained in law, contributed to more effective governance. Louis introduced regulations aimed at reforming the conduct of royal officials, forbidding blasphemy, gambling, and frequenting taverns, reflecting his desire to infuse the administration with moral rectitude. His two crusades, while reflecting his profound religious commitment, are more ambiguous in terms of success. The Seventh Crusade (1248-1254) ended in disaster with Louis’s capture in Egypt and required a hefty ransom. The Eighth Crusade in 1270 saw him die of dysentery near Tunis shortly after landing. From a purely military or geopolitical perspective, these were failures. However, in the context of medieval Christian values, undertaking crusades, even unsuccessful ones, enhanced a monarch’s prestige and demonstrated his devotion, contributing to his saintly reputation which, in turn, bolstered the moral authority of the French monarchy.

Comparing the extent of success of Charlemagne and Louis IX reveals the multifaceted nature of medieval rulership and how different contexts and priorities shaped achievements. Charlemagne’s success was largely defined by military prowess and the creation of a vast, albeit loosely federated, empire, crowned by the revival of an imperial title that held immense symbolic weight. His achievements reshaped the map of Europe and laid foundational myths for future political entities, particularly the Holy Roman Empire. However, the structural weaknesses of his state, heavily reliant on personal bonds and continuous conquest for resources, meant that its unity did not long survive his death, being divided among his grandsons by the Treaty of Verdun in 843. This suggests that while his personal success in accumulating power was immense, the institutional basis for its endurance was less secure. Louis IX’s success, conversely, was built upon strengthening the internal structures of the French state and grounding royal authority in law and moral legitimacy. His focus was less on expanding borders dramatically and more on making royal power more effective and respected within existing frontiers. The institutions he developed or reformed, particularly in the judicial sphere, proved more durable, contributing steadily to the long process of French state formation. McKitterick provides a valuable perspective on Carolingian Europe, stressing the dynamism and innovation of the period beyond just Charlemagne’s personal agency, including developments in monastic culture, intellectual life, and local governance. When evaluated, her work suggests that attributing success solely to the great man undervalues broader societal trends, though she certainly acknowledges Charlemagne’s pivotal role. Applied comparatively, this prompts consideration of the wider contexts influencing both rulers. Charlemagne operated in a post-Roman world where political fragmentation was the norm; his forging of an empire was thus extraordinary. Louis ruled at a time when monarchies across Europe were gradually consolidating, and his contribution was to refine and legitimise this process exceptionally well in France. The differing nature of sources also impacts perceptions of success; Einhard’s "Vita Karoli Magni" consciously shapes an imperial image, while Joinville’s biography of Louis focuses on his piety and justice. Both are constructs, though valuable ones. Ultimately, both rulers were highly successful within the parameters of their eras and aims. Charlemagne succeeded in creating an empire and a potent ideal; Louis IX succeeded in creating a more just and governable kingdom and becoming the epitome of Christian monarchy. Louis’s legacy of strengthened royal institutions perhaps proved more lasting in concrete terms of state development, while Charlemagne’s revival of empire provided a more enduring ideological framework for European politics. Their successes were of different kinds, but both significantly shaped medieval Europe according to their visions.

In conclusion, the rules of both Charlemagne and Louis IX can be regarded as highly successful, albeit with successes manifesting in distinct domains and with varying degrees of long-term institutional endurance. Charlemagne’s forceful unification of disparate territories under his imperial banner and his fostering of a cultural renewal represent monumental achievements that fundamentally altered the trajectory of Western Europe. The sheer scale of his conquests and the ideological power of his imperial coronation in 800 underscore a reign of extraordinary impact. However, the limited institutionalisation of his empire rendered its unity fragile and dependent on strong personal leadership, a fact borne out by its fragmentation after his death. Louis IX achieved profound success through less militaristic means, focusing instead on the meticulous consolidation of royal power within France through judicial innovation, administrative reform, and the embodiment of just and pious kingship. His canonisation serves as a powerful testament to his contemporary moral standing, which he skilfully leveraged to enhance the prestige and effectiveness of the French monarchy. The institutions he nurtured proved foundational for the later development of the French state. Therefore, while both rulers profoundly succeeded in elevating their authority and shaping their times, Louis IX’s endeavours perhaps resulted in more tangible and lasting state structures within his kingdom, whereas Charlemagne’s most enduring legacy lay in the powerful, though often contested, ideal of a unified Christian commonwealth in Europe.
