Dinar - Yusuf ibn Diwdad citing Abu'l-Hasan

The Sajid dynasty held Azerbaijan and parts of Armenia as governors nominally subordinate to the Abbasid caliphate, but their coinage tells a more complicated story. Yusuf ibn Diwdad — the most capable of the Sajid rulers — spent much of his reign pushing military campaigns into Armenia and fighting off Daylamite incursions, all while maintaining the careful diplomatic theater of citing Abbasid authority on his gold. The named Abu'l-Hasan on this piece is the caliph al-Muqtadir, who came to power as a child in 908 and whose early reign saw provincial strongmen operate with considerable autonomy.

This narrow two-year window of issue corresponds to a period of peak Sajid territorial reach before the dynasty's gradual eclipse by the Sallarids.
