Charles of Lorraine Captures Reims; Hugh Capet Seeks Arnulf’s Deposition (989–991)

Following his invasion of Reims in 989, Charles of Lorraine successfully captured the city and took Archbishop Arnulf—his own nephew—prisoner. This bold move marked a serious challenge to Hugh Capet’s authority, as Reims was the traditional coronation site of West Frankish kings and a center of royal legitimacy.

Hugh Capet’s Response: The Deposition of Arnulf

Despite being a Carolingian prince, Arnulf had initially been accepted as Archbishop of Reims by Hugh Capet. However, his betrayal and support for Charles led Hugh to consider him a traitor. In retaliation, Hugh:

• Refused to recognize Arnulf as archbishop, declaring him a turncoat for aiding the Carolingian claimant.
• Sought Papal intervention, demanding that Pope John XV depose Arnulf from his position.

The Struggle for Control of Reims

With Charles of Lorraine controlling Reims, the city briefly became a Carolingian stronghold, reinforcing his claim to the West Frankish throne. However, his failure to secure widespread support meant that his resurgence remained short-lived.

Hugh Capet’s diplomatic and political maneuvering against Arnulf and Charles would soon culminate in Charles' downfall and the final end of Carolingian ambitions in France.
