Lothair of West Francia

Lothair (941–986), son of Louis IV and Gerberga, succeeded his father at thirteen in 954, crowned at Reims under the guardianship of Hugh the Great.

In 978 he raided Lotharingia, nearly catching Otto II at Aachen; Otto ravaged to the walls of Paris, and by the 980 treaty of Margut Lothair renounced Lotharingia. His son Louis V was crowned co-king in 979, and after Otto II's death in 983 he claimed guardianship of the young Otto III. He died at Laon in March 986, planning to attack Cambrai.
