Rudolph of Burgundy: King of the Franks Between Princes and Normans (923–936)

In 923, the crisis between Charles the Simple and the aristocracy reaches a decisive turning point.

On 15 June 923, near Soissons, Charles faces the forces of Robert I. The battle is brutal: Robert is killed. But the king’s death does not mean a Carolingian victory. Thanks to the intervention of Hugh the Great, Robert’s son, and Herbert II of Vermandois, Charles is defeated and forced to retreat.

The death of Robert compels the kingdom’s great men to find a rapid political solution. They choose Rudolph of Burgundy (Raoul/Rodolphe), a powerful duke and, above all, Robert I’s son‑in‑law. This choice ensures continuity with the Robertian camp without placing the crown directly on the head of its main heir.

Rudolph is anointed on 13 July 923 at Soissons. But behind this election, the real pivot of power is Hugh the Great, count of Paris and duke of the Franks. His support is indispensable. He becomes the kingdom’s principal arbiter and will draw long‑term advantage from this position.

The new king nevertheless inherits an extremely fragile situation. Charles the Simple, still alive, remains a political threat. Before the end of 923, he is captured by Herbert II of Vermandois and imprisoned at Péronne. His captivity becomes a permanent instrument of pressure over royal power.

At the same time, the realm remains under military stress. Charles’s supporters, including Norman groups, continue to threaten northern territories. Hugh the Great, Archbishop of Reims Seulf, and Herbert organise defence on the left bank of the Oise, while a truce is concluded until spring 924.

Rudolph cannot limit himself to stabilising West Francia. As early as autumn 923, he launches an expedition into Lotharingia, besieges and takes Saverne with the support of the bishop of Metz Wigeric. Facing this offensive, Duke Gilbert and the archbishop of Trier appeal to the East Frankish king Henry the Fowler, who intervenes and ravages the region without securing durable allegiance from Lotharingian great men.

After obtaining submission from part of Lotharingia, Rudolph turns to another essential front: Aquitaine, where he tries to assert authority in a space dominated by powerful territorial princes.

Kingship now rests on an unstable balance:

• a king on the throne (Rudolph),
• a captive king (Charles),
• and princes — especially Hugh the Great — able to tip power.

🐉 923–926: Normans and permanent war

From the beginning of his reign, Rudolph faces an unavoidable reality: the Normans are durably established and can strike on multiple fronts.

As early as 923, they show their reach by besieging Clermont, indicating that their expeditions no longer remain confined to the North.

⚔️ 924: war, negotiation, and local defence

In 924, Rudolph seeks to stabilise the situation.

After making peace with William II of Aquitaine, he holds a full court at Autun and then at Chalon, where he organises power and rewards loyal men. But Viking pressure remains strong.

On 6 December 924, a coalition of counts and bishops — including Garnier of Sens, Manasses of Dijon, Ansegise of Troyes, and Gosselin of Langres — inflicts a severe defeat on the Viking leader Ragenold at Calaus mons.

This victory highlights a major evolution: defence increasingly rests on regional coalitions, rather than the royal army alone.

At the same time, Rudolph chooses compromise: he grants Rollo new territories, notably the Bessin (and probably Maine), to secure a relative peace.

🔥 925: raids resume, Frankish responses

Peace remains fragile.

In 925, the Normans break the truce and renew offensives:

• Amiénois and Beauvaisis are ravaged,
• Amiens and Arras are burned,
• Noyon resists.

Local forces respond. Men from the Bessin and the Paris region, dependent on Hugh the Great, counter‑attack in Norman territories, forcing a retreat.

Rudolph regains the initiative in summer. He gathers his vassals and besieges the Norman castle of Eu, which he captures.

But the situation remains unstable: in August 925, Hugh the Great makes his own agreement with the Normans, showing that conflict management depends not only on the king but also on major princes.

⚠️ 926: royal defeat and tribute

The year 926 turns against the king.

In January 926, Rudolph is defeated at Fauquembergues, on the Aa. Count Helgaud of Montreuil is killed and the king is badly wounded. He survives thanks only to Herbert II of Vermandois.

Weakened, Rudolph negotiates and pays a tribute to the Vikings — the last major tribute paid in West Francia.

This defeat shows the limits of royal power:

• military dependence on the great,
• unstable alliances,
• inability to impose durable domination.

⚖️ 926–930: princes against princes, a fragmented kingdom

After the defeat of 926, conflict is no longer only against the Normans: it is also between the kingdom’s great men.

The rivalry between Hugh the Great and Herbert II of Vermandois becomes central. Herbert strengthens his position by exploiting a major asset: Charles the Simple, whom he releases in 927 and again recognises as legitimate king.

He even allies with the Seine Normans: William Longsword pays homage to Charles.

Rudolph must intervene. A confrontation takes place on the Oise, but through Hugh’s mediation a compromise is reached: Herbert gives hostages and accepts negotiations.

In 928, Herbert obtains Laon, a crucial strategic stronghold, in exchange for rallying. Charles the Simple is again sidelined and returned to captivity.

These events show that royal power is now secondary to princely ambitions, as princes control:

• territories,
• fortresses,
• and claimants to the throne.

⚰️ 929: the end of a captive king

In 929, Charles the Simple dies in captivity.

His death deeply changes the political situation. For years, Herbert II could threaten to release the Carolingian to weaken Rudolph. This dynastic lever disappears.

But this does not truly strengthen royal authority. The problem is no longer dynastic: it is structural. Power rests with princes, and the king must negotiate with them.

🧱 930–936: a king as arbiter in a kingdom of princes

In the 930s, Rudolph’s reign enters a new phase. War against the Normans gradually recedes, but the kingdom remains unstable. The main challenge is now political.

Rudolph must act as an arbiter among aristocratic powers, especially between Hugh the Great and Herbert II of Vermandois, whose rivalry structures political life.

⚖️ 930–932: arbitrating great men’s conflicts

In 930, Rudolph is at Autun (23 March), but he is quickly forced to intervene in northern conflicts.

Rivalry escalates when Ernaut of Douai, Hugh’s vassal, joins Herbert’s camp. The king mediates. An agreement is reached:

• Boson, Rudolph’s brother, should recover Vitry‑en‑Perthois,
• but tensions immediately resume, fuelled by betrayals and shifting alliances.

Conflict degenerates into a feudal war:

• Douai is besieged and taken by Hugh’s allies,
• Saint‑Quentin and Coucy change hands,
• Mouzon is taken and retaken.

The king no longer controls territory directly; he tries to regulate conflicts.

In 931, Rudolph tightens his alliance with Hugh. Together, they retake Reims and impose a new archbishop, Artald, replacing Herbert’s son.

They also retake Laon. Herbert seeks help from Henry the Fowler, without immediate success.

Rudolph must also suppress unrest in Burgundy. He returns to face revolts, notably those of Garnier of Sens and Gilbert of Dijon, who submit in 932.

🌍 932–934: a fragmented yet stabilised kingdom

In 932, several southern princes, including Raymond Pons of Toulouse and Gascon lords, pay homage to Rudolph, showing that authority is still recognised in parts of the realm.

In the North, struggle continues:

• Herbert takes new places,
• Hugh retakes Amiens and Saint‑Quentin,
• Péronne still resists.

Rudolph intervenes personally and retakes some points, including the abbey of Saint‑Médard of Soissons, a symbol of power.

In 933, the king also acts territorially:

• he intervenes in the Rhône valley to support Charles‑Constantine at Vienne,
• and grants William Longsword the Cotentin and Avranchin, durably strengthening Normandy.

War against Herbert continues: Château‑Thierry is besieged, cities change hands, no victory is decisive.

In 934, a new campaign against Herbert is led with Hugh. After months of siege, an armistice is imposed through Henry the Fowler’s intervention.

---

🤝 935: a balance of powers

The year 935 brings relative calm.

Rudolph gathers the great men at a plaid at Soissons, then meets neighbouring rulers, notably Henry the Fowler and Rudolph II of Burgundy, at a meeting on the Chiers.

A major agreement is concluded:

• Herbert II submits to the king,
• peace is restored between Herbert and Hugh,
• territorial balances are stabilised.

In a charter issued at Attigny, Rudolph affirms a will to govern through peace and trust, not war.

This is the outcome of his reign: not a military triumph, but a negotiated political equilibrium.

⚰️ 936: the end of a king‑arbiter

Weakened by illness, Rudolph dies on 15 January 936 at Auxerre.

His reign does not restore a strong monarchy, but it maintains balance in a kingdom dominated by princes.

At his death, power returns to those who effectively wield it: the kingdom’s great men, especially Hugh the Great, who chooses to recall a Carolingian, Louis IV.

⚰️ 936: Rudolph’s death and the Carolingian return

Rudolph dies on 15 January 936 at Auxerre, without an heir able to succeed him durably.

Once again, the decision belongs to the great. The key figure is Hugh the Great, now the principal “kingmaker”.

Rather than taking the crown himself, he recalls a Carolingian: Louis IV, called “d’Outremer”, raised in England.

The choice confirms a political reality:
kingship is no longer an autonomous power, but a function granted and controlled by the aristocracy.
