Zwentibold was a Carolingian monarch who ruled the kingdom of Lotharingia from 895 until his death in 900. As the illegitimate son of Emperor Arnulf, he was granted the Lotharingian throne to compensate for his lack of succession rights in East Francia following the birth of his half-brother, Louis the Child. His reign was characterized by conflicts with local nobility and unsuccessful military campaigns in Italy, eventually leading to his downfall and death in battle.
