Why the twelfth century looks like a high point
When readers imagine the medieval empire at its brightest, they often picture the Hohenstaufen world from Frederick I Barbarossa’s election in 1152 to Frederick II’s death in 1250. That impression is not baseless. Barbarossa brought unusual energy to kingship, travelled relentlessly, restored royal authority in parts of Germany after the upheavals of the Investiture Contest, and made the imperial office look formidable again. His chancery also sharpened the language of rulership. The phrase sacrum imperium entered imperial usage in the 1150s in precisely this context of Italian ambition and elevated political claims. Later historians have likewise treated his reign as a moment when the crown again seemed capable of acting on a grand European stage.
Yet the very same period that made the Empire look strong also exposed its limits. The northern Italian communes were not waiting passively to be ruled. As Chris Wickham has argued, the cities of the kingdom of Italy had already developed forms of collective government that were innovative, local, and increasingly self-confident. They were run by urban elites, not democracies in any modern sense, but they were no longer simply obedient instruments of kings, counts, or bishops. In practice, Barbarossa’s “high noon” was also the moment when imperial restoration collided with a political order that had changed beneath imperial feet.
This tension helps explain why Barbarossa’s reign became both a symbol of grandeur and a warning against nostalgia. The crown still possessed prestige, ceremony, lawyers, armies, and inherited claims. What it lacked in northern Italy was the easy obedience that those claims assumed. The result was not a simple struggle between order and rebellion. It was a contest between competing ideas of legitimacy: imperial regalian right on one side, communal self-government on the other.
“The Lombard League has enjoyed an iconic status.”
— Gianluca Raccagni, The Lombard League, 1167–1225
That iconic afterlife matters because it can distort history. The Hohenstaufen period was not a straightforward age of imperial mastery. It was the age in which the Empire most visibly tried to master Italy and, in doing so, made plain how difficult that project had become.
Barbarossa’s programme: restoring rights, asserting presence
Bust of Friedrich I, Barbarossa, gilded bronze, ca. 1160
Barbarossa came to the throne in March 1152 and was crowned emperor in Rome in June 1155. From the start, Italy stood near the centre of his political imagination. He did not regard the Kingdom of Italy as a distant appendage. It was one of the constituent realms of the Empire, and he intended to exercise there the rights that earlier rulers had allowed to drift. That meant more than prestige. It meant jurisdiction, taxation, appointments, appeals, and the visible presence of monarchy.
The clearest statement of this programme came at Roncaglia in 1158. There, with the support of the Bologna jurists and Roman-law reasoning, Barbarossa sought to define and reclaim the emperor’s regalia in Italy. Later legal commentary remembered the Roncaglia settlement in stark terms: omnis iurisdictio et omnis districtus apud principem est — all jurisdiction and coercive authority reside in the prince. Even when paraphrased rather than quoted, the point is unmistakable. Barbarossa wanted to turn inherited theory into enforceable government.
This was not an empty abstraction. Roncaglia was meant to make imperial government concrete. The crown claimed rights over tolls, roads, justice, public revenues, and the very exercise of office inside the cities. Such measures were perfectly intelligible from the imperial side. If the king of the Romans was also king of Italy, then the public powers of the kingdom ought not to have dissolved into a patchwork of civic custom and local appropriation. But what looked like restoration from the court could be an encroachment by Lombardy.
Barbarossa also understood that medieval rule depended on showing up. He went to Italy repeatedly because rights not exercised were rights likely to vanish. His reign combined legal assertion with itinerant presence, display, military coercion, and carefully staged encounters. This was kingship in motion. It was also expensive and fragile. Each journey south demanded money, negotiation with princes north of the Alps, and continued success on the ground. The imperial programme was therefore more impressive in conception than in its capacity for permanent enforcement.
Milan was the turning point in the early phase. Its dominance over weaker neighbours, combined with its refusal to yield to imperial discipline, made it the chief urban antagonist. After the enforcement of the Roncaglian programme triggered wider resistance, Milan was besieged and destroyed in 1162. On paper, this looked like a spectacular vindication of imperial might. In practice, it proved otherwise. The destruction of one great commune did not settle the problem of the communes as a political class. It hardened the conflict and helped create the very coalition that would later defeat Barbarossa.
Northern Italy and the limits of imperial power
Northern Italy was difficult for any ruler because it was urban, wealthy, quarrelsome, and politically mature. By the mid-twelfth century, its cities had magistrates, assemblies, legal cultures, militias, rivalries, and regional ambitions of their own. They could fight one another fiercely, yet under pressure, they could also combine. Wickham’s account of early communal development stresses both novelty and continuity: the elites were often longstanding local families, but the political framework in which they acted had become much more autonomous than before. Barbarossa was not confronting anarchy. He was confronting a different order.
That different order partly explains why the Lombard League mattered so much. Formed between 1164 and 1167, and consolidated in the face of imperial pressure, it was more than an emergency alliance. Gianluca Raccagni’s work has shown that the League developed durable structures, documentary practices, and diplomatic significance. It defended communal autonomy, but it also became a framework through which cities could coordinate military resistance and political bargaining on a regional scale.
The papacy strengthened this resistance, especially during the Great Schism. Alexander III supported the League against Barbarossa, but the relationship was never identical to a simple papal command. The communes had their own reasons to resist imperial encroachment. Papal backing helped make imperial coercion harder, yet the roots of the conflict lay inside the kingdom of Italy itself: who possessed public authority there, and on what terms?
This is why the image of the Empire at full blaze must be handled carefully. Barbarossa’s resources were real, but northern Italy was not a blank space awaiting administration. City governments had deep local legitimacy. Their military forces were not always elegant, but they were politically motivated and regionally networked. The imperial host could win campaigns, especially when city rivalries worked in its favour, yet it struggled to transform victory into settled rule.

Legnano and negotiated outcomes
The Battle of Legnano – Massimo Tapparelli d’Azeglio
The battle that came to symbolise the whole struggle was fought near Legnano on 29 May 1176. There, the forces of the Lombard League defeated Barbarossa’s army. Medieval and later accounts disagree about precise numbers and even about aspects of the battle’s sequence. Peter Munz’s discussion of Boso’s narrative is a useful warning: one prominent near-contemporary account is dramatic, vivid, and not consistently reliable in outline. That uncertainty should temper confidence in detailed reconstruction. It does not alter the central fact that Legnano changed the political balance.
What made Legnano famous was not merely that an emperor lost a battle. Emperors could lose battles and recover. What gave this defeat lasting force was who won and what that implied. A coalition of communes, drawing on civic militias and urban solidarity, had shown that imperial chivalric prestige did not automatically translate into obedience. Later scholars have rightly stressed the wider significance: the battle demonstrated that organised urban communities could resist the mounted aristocratic power that had seemed militarily and socially dominant.
Legnano did not by itself settle the war. What it did was make serious negotiation unavoidable. The Peace of Venice in 1177 ended the schism between Barbarossa and Alexander III and established a truce with the Lombard League. That agreement did not immediately solve the constitutional issue inside the Kingdom of Italy, but it opened the road to a more durable settlement.
The decisive constitutional outcome came with the Peace of Constance in 1183. This settlement is often described as a defeat for the imperial programme, but that needs precision. It was not pure imperial surrender. As Raccagni has argued, the peace formalised city autonomy while also recognising enduring imperial superiority and prerogative. The Fordham translation of the text makes the compromise visible: the emperor granted the League’s cities extensive rights, including the regalia they had been accustomed to hold, while reserving certain matters and preserving oaths of loyalty and imperial investiture.
That is why Constance matters so much. It acknowledged that the Empire could not simply govern northern Italy as Roncaglia had imagined. But it also refused the fiction that the communes had become wholly sovereign in a later modern sense. The cities retained broad self-government, their offices, and their legal life. The Empire retained overlordship, appellate claims, and symbolic superiority. It was a negotiated order born from mutual exhaustion and altered fact.
The long shadow of Italy on German politics
Italy did not merely complicate imperial policy south of the Alps. It changed the politics of the kingdom north of them as well. Barbarossa’s ambition and repeated Italian campaigning demanded cooperation from German princes, ecclesiastics, and great families. He was often skilful in securing it. John Freed’s biography emphasises his diplomatic talents and the durability of his rule. But the same period also helped entrench a pattern in which emperors needed princely backing for large projects and could not indefinitely centralise power against them. Freed explicitly links Barbarossa’s reign to the legalisation of a lasting dualism between crown and princes.
In other words, the “high point” contained the seeds of decentralisation. The crown remained prestigious, but governance in Germany depended on negotiation with territorial powers whose own authority was increasing. Italy intensified this because every descent across the Alps cost political capital at home. Military expeditions required support. Failures weakened the monarch’s bargaining position. Successes, even when real, did not abolish the structural need to work through princes rather than around them.
Martin Kaufhold’s recent account of thirteenth-century Germany is especially useful here. He argues that traditional kingship centred on Roman imperial ambitions underwent a reality test and failed in Frederick II’s time. That judgement reaches beyond Frederick II himself. It points back to the larger Hohenstaufen inheritance. The pursuit of Italy preserved imperial universality as an ideal, but it also diverted time, attention, and presence away from Germany, where rulership still required the king’s body, court, and judgement.
The result was not state collapse. It was rebalancing. Princes, bishops, and territorial lords deepened their position inside the Empire while the monarchy remained grand in title and uneven in reach. The “Italian problem” was therefore not just a foreign entanglement. It was one of the main reasons why later fantasies of full imperial restoration would continue to jar against the Empire’s actual constitutional development.
Frederick II and the end of the line
Frederick II inherited both the magnificence and the burden of this legacy. Crowned emperor in 1220, king of Sicily from childhood, and ruler across multiple realms, he looked in some ways even more dazzling than his grandfather. David Abulafia’s biography remains essential precisely because it strips away later myth. Frederick II has often been cast as an almost modern genius outside his age. Abulafia argues instead that he was in important respects a traditional emperor, committed to dynasty and empire in recognisably medieval terms.
His Sicilian kingdom shows the scale of his ambition. The Liber Augustalis of 1231, preserved in later manuscripts and modern translations, laid out a forceful vision of monarchy, justice, and public order. It is one of the great legislative monuments of medieval Europe, and it reveals Frederick as a ruler who thought systematically about authority.
“peace and justice, which embrace each other like two sisters”
— Liber Augustalis of Frederick II, translated by James M. Powell
Material culture from Frederick’s court reinforces the point. The Vatican’s manuscript Pal. lat. 1071 of De arte venandi cum avibus testifies to one of the most extraordinary intellectual productions associated with a medieval ruler, while Castel del Monte remains a physical monument to the cultural synthesis and architectural ambition of his southern kingdom. Neither object tells us that Frederick was “modern” in a simple sense, but both show the remarkable range and confidence of his court.
And yet Frederick II could not solve the Italian question. The Lombard League revived against him after 1226, and the conflict became more entangled with papal ideology than in Barbarossa’s day. Raccagni’s work on Gregory IX and the “Lombard question” shows how, in the thirteenth century, heresy, penitential warfare, and crusading rhetoric entered the struggle more deeply than they had under Alexander III. The older contest between the emperor, communes, and the papacy returned in harsher form.
Frederick did win major victories, most famously at Cortenuova in 1237, but success did not produce a final settlement. J. A. Watt’s chapter in The New Cambridge Medieval History underlines that Frederick at first prospered militarily in Lombardy, only to lose ground again as relations with Gregory IX collapsed into renewed excommunication and total hostility. When Frederick died in December 1250, he was still unreconciled to the papacy, and no Peace of Constance equivalent had ended the second great Hohenstaufen struggle in the north. Raccagni makes the point bluntly: unlike the earlier conflict, no settlement was achieved while the war still raged.
The dynasty’s afterlife was brief and violent. Conrad IV died in 1254. Manfred fell in 1266. Conradin was executed in 1268. The Hohenstaufen did not vanish the moment Frederick II died, but the line no longer possessed the authority, legitimacy, or geopolitical room to restore what had been lost.
Why this matters for what came next
Rudolf I of Habsburg / Austria
The importance of 1152–1250 lies not only in its pageantry or its famous battles. It lies in the way it clarified the shape of the medieval Empire. The Hohenstaufen were strongest when they looked most universal. They were weakest when they tried most insistently to turn that universality into direct rule over Italy’s cities. Barbarossa learned this through Roncaglia, Milan, Legnano, Venice, and Constance. Frederick II learned it again, on a larger stage and with higher ideological stakes.
After 1250, the old Roman-imperial horizon did not disappear, but its political centre of gravity shifted. Kaufhold argues that one era of European pretensions ended in Frederick II’s time. When Rudolf of Habsburg revived kingship in 1273, he focused on Germany and never went to Rome. That was not a mere accident. It reflected a changed world in which the monarchy could no longer live as if Lombardy, Rome, and Germany naturally formed one governable field under a constantly present emperor.
That is the real meaning of the Hohenstaufen “high noon”. It was bright, imposing, and unforgettable. It also cast a long shadow. The political vacuum after Frederick II was not simply the collapse of a dynasty. It was the collapse of a particular hope: that the Empire could permanently restore ancient-scale authority in Italy without remaking the local realities that now stood in its way. What followed was not imperial disappearance, but an Empire learning, painfully, to live with that fact.
