The Overthrow and Imprisonment of Geoffrey III …

Years: 1068 - 1068

The Overthrow and Imprisonment of Geoffrey III by Fulk IV (1067–1068)

By 1067, Anjou was in crisis, as the ongoing deterioration of Angevin power led to an open conflict between the two brothers, Geoffrey III and Fulk IV ("le Réchin"). Fulk, dissatisfied with his brother’s weak rule and military failures, rebelled against Geoffrey, seizing control of the county of Anjou and imprisoning him for nearly three decades.


Fulk IV’s Rebellion and the Fall of Geoffrey III (1067)

  • Geoffrey III had already alienated his vassals through military failures, including the loss of Maine to William of Normandy in 1063 and Saintonge in 1062.
  • By 1067, tensions between Geoffrey and his younger brother Fulk IV erupted into outright rebellion.
  • Fulk IV rose in revolt, capturing the county of Anjou and briefly imprisoning Geoffrey, though Geoffrey would escape or be released soon after.

Geoffrey’s Attempt to Regain Power and Final Defeat (1068)

  • In 1068, Geoffrey attempted a counteroffensive, gathering support to reclaim Anjou from Fulk IV.
  • However, he was decisively defeated, marking the end of his rule as Count of Anjou.
  • This time, Fulk ensured Geoffrey would never pose a threat again, imprisoning him for an extraordinary twenty-eight years.

Geoffrey’s Long Imprisonment and Ultimate Fate (1068–1096)

  • Geoffrey remained in captivity for nearly three decades, his existence largely forgotten as Fulk IV solidified his rule over Anjou.
  • In 1096, during the rise of Pope Urban II, the pope personally intervened to secure Geoffrey’s release.
  • However, Geoffrey died soon after, never regaining any power or influence.
