Whatever Makhir's Babylon origins claimed by his descendants, the relation between Makhir and Charlemagne is legendary, the more famous king substituting for his father Pepin, king of the Franks, who in order to enlist the Jews of Narbonne in his efforts to keep the Ummayad Saracens at bay, granted wide-ranging powers in return for the surrender of Moorish Narbonne to him in 759. The "Annals of Aniane" and the "Chronicle of Moissac" both attribute this action to the "Gothic" leaders of Narbonne, rising up and massacring the Saracen garrison. Pepin with his sons Carloman and Charles redeemed this pledge in 768, granting to Makhir and his heirs extensive lands, an act that called forth an unavailing protest from Pope Stephen III. In 791 Charlemagne confirmed the status of the Jewish Principate and made the title of "Nasi" permanent.
