Which Monarchies Fought Intermittently During The Hundred Years War

The Hundred Years' War: A Clash of Crowns and Ambitions

The Hundred Years’ War wasn’t just a single, uninterrupted conflict—it was a series of brutal battles, truces, and shifting alliances that spanned over a century. At its heart was a simple, yet devastating, question: who had the right to rule France? That's why the answer hinged on a tangle of dynastic claims, feudal loyalties, and the ambitions of two monarchies: England’s Plantagenets and France’s Valois. But this wasn’t just a battle between kings—it was a war that reshaped the political landscape of medieval Europe, leaving scars that lasted for generations.

What Was the Hundred Years’ War, and Why Did It Happen?

The Hundred Years’ War (1337–1453) was a prolonged conflict between the Kingdom of England and the Kingdom of France, sparked by a dispute over the French throne. The immediate cause was the death of King Charles IV of France in 1328, who left no male heir. His nephew, Philip VI, a member of the House of Valois, claimed the throne, but Edward III of England, the son of Charles IV’s sister Isabella, also laid claim. On top of that, edward argued that his mother’s lineage gave him a stronger claim than Philip’s. This dynastic tangle set the stage for decades of warfare, with both sides mobilizing armies, forging alliances, and fighting for control of key territories.

The war wasn’t just about who wore the crown—it was about power, territory, and the very definition of sovereignty. The English kings, who had long held lands in France (like Gascony), saw themselves as vassals to the French king, but they also believed they had a right to rule France itself. That said, the French, on the other hand, were determined to assert their independence and prevent English interference. This clash of identities—English kings as both vassals and claimants—created a unique tension that fueled the war’s longevity.

Why the Conflict Wasn’t a Straightforward Battle Between Two Monarchies

The Hundred Years’ War wasn’t a simple back-and-forth between England and France. Because of that, while the English and French monarchies were the primary belligerents, other European powers played significant roles. Day to day, it was a complex web of alliances, shifting loyalties, and internal struggles. Here's one way to look at it: the Kingdom of Scotland, which had its own conflicts with England, sometimes aligned with France, while the Holy Roman Empire and various duchies and city-states were drawn into the fray. The war also saw the rise of new military tactics, like the use of longbows and gunpowder, which changed the nature of warfare.

Also worth noting, the war wasn’t fought in a single, continuous campaign. It was marked by periods of intense fighting, followed by truces and negotiations. These pauses often allowed both sides to regroup, rebuild their forces, and reassess their strategies. The conflict was also shaped by internal politics—English nobles sometimes rebelled against their king’s decisions, and French factions vied for influence. This made the war less about two monarchies and more about a broader struggle for dominance in a fragmented Europe.

The Key Players: England’s Plantagenets and France’s Valois

At the heart of the Hundred Years’ War were two dynasties: the Plantagenets of England and the Valois of France. Which means their claim was rooted in the marriage of Henry II of England to Eleanor of Aquitaine, which gave them vast territories in France. The Plantagenets, who ruled England from 1154 to 1485, were a powerful family with a long history of claiming the French throne. Still, by the time of the war, the English kings had lost much of this land, but their claim to the French crown remained a symbolic and strategic asset.

The Valois, on the other hand, were a relatively new dynasty that emerged in the 14th century. They were the descendants of Philip IV of France, and their rise to power was marked by a series of conflicts, including the War of the Breton Succession and the War of the Burgundian Succession. The Valois kings, particularly Philip VI and his successors, were determined to assert their authority over France and resist English encroachment. Their ability to rally support from the French nobility and common people was crucial to their survival in the war.

The Role of Other European Powers in the Conflict

While England and France were the main combatants, the Hundred Years’ War was far from a two-sided struggle. Other European powers played significant roles, often as allies or rivals. This alliance was a strategic move to counter English influence and protect Scottish interests. Here's a good example: the Kingdom of Scotland, which had its own conflicts with England, frequently sided with France, forming the Auld Alliance. Similarly, the Holy Roman Empire, though not directly involved in the war, had its own interests in the region, and its rulers sometimes intervened to balance the power of France and England.

The war also saw the involvement of various duchies and city-states, such as Burgundy and the Duchy of Brittany. In practice, these regions were often caught in the crossfire, with their rulers switching allegiances based on which side offered them the most benefits. The complexity of these alliances made the war a dynamic and unpredictable conflict, with shifting loyalties and changing objectives.

The Impact of the War on Medieval Europe

The Hundred Years’ War had profound consequences for the political and social structures of medieval Europe. For France, the conflict was a catalyst for the consolidation of royal power, as the Valois kings worked to centralize authority and reduce the influence of the nobility. For England, the war drained resources and weakened the monarchy, leading to internal strife and the eventual rise of the Tudor dynasty. The war also accelerated the decline of feudalism, as the need for standing armies and centralized governance became more apparent.

Beyond the immediate combatants, the war reshaped the balance of power in Europe. Think about it: meanwhile, the French victory solidified the Valois dynasty’s rule and set the stage for the rise of a more unified French state. The English defeat at the Battle of Agincourt (1415) and the eventual loss of their French territories marked the end of English claims to the French throne. The war also highlighted the importance of military innovation, as both sides adapted to new technologies and tactics, laying the groundwork for future conflicts.

Why the Hundred Years’ War Still Matters Today

The legacy of the Hundred Years’ War extends far beyond the medieval period. In real terms, it serves as a case study in the complexities of dynastic claims, the challenges of maintaining alliances, and the role of military innovation in shaping history. The war also underscores the importance of national identity, as both England and France used the conflict to define their sovereignty and cultural distinctiveness.

For modern historians, the war is a reminder of how political ambitions and personal rivalries can have far-reaching consequences. It also highlights the resilience of medieval institutions, as both England and France emerged from the conflict with stronger, more centralized governments. The Hundred Years’ War wasn’t just a struggle for a throne—it was a important moment in the evolution of European power structures, with effects that are still felt today.

Conclusion: A War That Shaped the Modern World

The Hundred Years’ War was more than a clash between two monarchies—it was a defining moment in the history of Europe. The conflict between the Plantagenets and the Valois, along with the involvement of other powers, created a dynamic and unpredictable struggle that reshaped the political landscape. Still, from the rise of centralized monarchies to the decline of feudalism, the war left an indelible mark on the medieval world. Its legacy continues to influence our understanding of power, identity, and the enduring impact of historical conflicts.
