The Norman Conquest of Maine (1063–1064) and Its Role in William’s Rise to Power

By 1063, the County of Maine was in Angevin hands, but a succession crisis following the death of Count Herbert II in 1062 created an opportunity for Duke William of Normandy to assert his own claim over the region. This campaign, marked by stiff resistance from Fulk IV of Anjou and local barons, was crucial in securing Normandy’s southern border and setting the stage for William’s invasion of England in 1066.

Competing Claims to Maine

After Herbert II’s death, two rival factions vied for control of Maine:

1. William’s Claim via Margaret of Maine

   • Herbert II’s young sister, Margaret, was betrothed to William’s son, Robert Curthose.
   • William claimed the county in her name, arguing that this secured her rightful inheritance.

2. The Claim of Biota and Walter of the Vexin

   • Biota, Herbert II’s aunt, and her husband, Walter, Count of the Vexin, asserted their own claim to the county.
   • They gained support from local barons and the Angevins, creating a strong opposition to Norman rule.

William’s Military Campaign (1063–1064)

• In 1063, William invaded Maine in force, launching a well-coordinated attack on the county’s key strongholds.
• The invasion met heavy resistance from:
  • Fulk IV of Anjou, who sought to keep Maine under Angevin control.
  • Local barons, such as Geoffrey of Mayenne and Hubert de Sainte-Suzanne, who resisted Norman domination.
• Despite the stiff opposition, William overran Maine by early 1064, effectively bringing it under Norman control.

The Fate of Biota and Walter: Allegations of Poisoning (1063)

• Biota and Walter were captured when William took Le Mans, the capital of Maine.
• Sometime later in 1063, both died under mysterious circumstances, leading to rumors that they had been poisoned by the Normans.
• Their deaths eliminated the rival claim to Maine, leaving William’s rule uncontested.

Significance and Impact of the Conquest of Maine

• Securing Maine ensured William’s southern border, neutralizing Angevin threats before his campaign in England.
• Maine’s conquest reinforced William’s reputation as a formidable military leader, proving his ability to subdue rebellious barons and rival claimants.
• The county’s strategic location gave Normandy a stronger defensive position, allowing William to shift his focus toward his claim on the English throne.

The Norman conquest of Maine (1063–1064) was a key prelude to the Norman Conquest of England, giving William the territorial security and strategic advantage needed for his historic invasion in 1066.
