Which Monarchies Fought Intermittently During The Hundred Years War

The Hundred Years' War (1337‑1453) was not a single, continuous conflict but a series of intermittent clashes between two major monarchies: the House of Plantagenet of England and the House of Valois of France. Understanding how these dynasties fought, allied, and switched sides over more than a century reveals the complex political landscape of medieval Europe.

Introduction

The Hundred Years' War is often portrayed as a straightforward struggle for territorial control, but the reality involved shifting loyalties, internal strife, and external alliances. In real terms, the two principal monarchies—England’s Plantagenets and France’s Valois—were the dominant powers in the conflict, yet other royal houses, such as the Burgundians, the Armagnacs, and the Navarrese, also played central roles. This article examines the monarchies that intermittently fought during the war, exploring their motivations, key battles, and the ways in which their alliances reshaped the course of the war.

The Primary Dynasties

1. House of Plantagenet (England)

• Edward III (r. 1327‑1377): Initiated the war by claiming the French crown, citing his maternal lineage (his mother, Isabella of France, was a daughter of Philip IV). Edward’s claim set the stage for a prolonged conflict.
• Richard II (r. 1377‑1399): Continued hostilities but faced internal challenges in England, leading to a more limited military focus.
• Henry IV (r. 1399‑1413): Took the throne through a coup, yet maintained the war’s objectives, though his reign was marked by domestic instability.
• Henry V (r. 1413‑1422): Revitalized the war effort, achieving decisive victories at Agincourt (1415) and Vaucouleurs (1420). His campaign exemplified the Plantagenet commitment to French conquest.
• Henry VI (r. 1422‑1461, 1470‑1471): Inherited a precarious position; his reign saw the eventual loss of English territories in France.

2. House of Valois (France)

• Charles V (r. 1364‑1380): Known as Charles the Wise, he reorganized the French army and reclaimed lost territories, countering Plantagenet advances.
• Charles VI (r. 1380‑1422): His mental illness led to a fragmented French leadership, creating opportunities for English gains.
• Charles VII (r. 1422‑1461): Reclaimed French sovereignty with the help of Joan of Arc, culminating in the expulsion of the English from most of France.

Secondary Dynasties and Their Roles

3. House of Burgundy

• Philip the Good (r. 1419‑1467): Initially allied with England, the Dukes of Burgundy controlled vast territories in northern France. Their intermittent support for the English shifted the balance of power multiple times.
• Charles the Bold (r. 1467‑1477): Continued Burgundy’s influence, though his reign postdated the main conflict.

4. House of Armagnac

• Charles, Count of Ponthieu (r. 1415‑1435): A French noble who led the Armagnac faction, opposing Burgundian interests and aligning with the French crown against England.
• John, Count of Armagnac (r. 1435‑1456): Continued the Armagnac resistance, playing a key role in the internal French struggle that indirectly affected the war’s outcome.

5. House of Navarre

• John II of Navarre (r. 1349‑1387): Though not a primary combatant, Navarre’s strategic location and alliances influenced border skirmishes between English and French forces.

6. House of Castile (Spain)

• Henry II of Castile (r. 1369‑1379): Engaged in the Castilian Civil War, but his diplomatic maneuvers occasionally affected English-French dynamics, especially through the Treaty of Leulinghem (1356).

Intermittent Alliances and Shifts

The war’s intermittent nature stemmed from the fluid allegiances among these monarchies:

During these periods, the Dukes of Burgundy oscillated between supporting England and aligning with France, while the Armagnac faction remained staunchly pro-French. These internal French divisions, coupled with English resource constraints, created a war that ebbed and flowed over a century.

Scientific Explanation of Warfare Dynamics

The intermittent nature of the conflict can be understood through several socio‑political factors:

1. Feudal Loyalties: Knights and nobles pledged allegiance to multiple overlords, leading to conflicting commitments. When a noble’s primary allegiance shifted, so did local military support.
2. Economic Strain: Prolonged campaigns drained royal treasuries. England’s reliance on taxation of the nobility and French taxation of the peasantry created fiscal pressures that forced temporary truces or peace negotiations.
3. Diplomatic Marriages: Royal marriages forged temporary alliances. To give you an idea, the marriage of Henry V to Catherine of Valois linked the Plantagenet and Valois houses, influencing the war’s later stages.
4. Military Innovations: The introduction of the longbow by English archers and the use of cannon by French forces altered battlefield dynamics, causing intermittent surges in combat intensity.

Frequently Asked Questions (FAQ)

Q1: Why did the war last so long despite decisive battles?

A1: The war was interrupted by truces, diplomatic negotiations, and internal crises within both kingdoms. Each side’s ability to recover and regroup after losses prolonged the conflict.

Q2: Did other European monarchies influence the war?

A2: Yes, the Dukes of Burgundy, Armagnac, and even the Spanish crown through diplomatic channels impacted the war’s direction by providing troops, funds, or strategic alliances.

Q3: What was the significance of Joan of Arc in the conflict?

A3: Joan’s leadership revitalized French morale and led to the capture of Orléans in 1429, turning the tide against the English and marking the beginning of the end of English territorial claims in France.

Q4: How did the war affect common people?

A4: Prolonged warfare led to famine, displacement, and economic hardship. Peasants often faced conscription or tribute demands, while towns suffered from sieges and raids. Took long enough.

Q5: When did the war officially end?

A5: The war concluded with the Treaty of Castillon in 1453, after the French victory at the Battle of Castillon, effectively ending English control over French territories except Calais.

Conclusion

Here's the thing about the Hundred Years' War was a complex, multi‑decadal struggle dominated by the Plantagenet and Valois monarchies but shaped significantly by the intermittent involvement of the Burgundian, Armagnac, Navarrese, and Spanish houses. Their shifting alliances, internal conflicts, and diplomatic maneuvers created a war that was as much about political survival as territorial conquest. Understanding these dynamics offers insight into how medieval European powers negotiated, fought, and ultimately reshaped the political map of the continent.
