Badr al-Mu'tadidi, commander-in-chief of the Abbasid Caliphate under al-Mu'tadid
Abu'l-Najm Badr al-Mu'tadidi was the chief military commander of the Abbasid Caliphate during the reign of Caliph al-Mu'tadid (892–902). Originally a military slave (ghulam or mawla) who served under the future al-Mu'tadid in the suppression of the Zanj Rebellion, his ability and loyalty led him to become the Caliph's commander-in-chief, exercising considerable influence in the governance of the state throughout Mu'tadid's reign. He was executed on 14 August 902 due to the machinations of the ambitious vizier, al-Qasim ibn Ubayd Allah.
