1 Dinar - Ali b. Muhammad Zabid, Citing Fatimid caliph al-Mustansir

The Sulayhids, who came to power in Yemen in the 1040s under Ali b. Muhammad al-Sulayhi, were committed Ismaili partisans — their recognition of the Fatimid caliph al-Mustansir on coinage was a deliberate political alignment with Cairo against the Sunni Abbasid caliphate in Baghdad. This coin was struck within a decade of the dynasty's founding, when Ali al-Sulayhi was consolidating control over the Yemeni highlands through a combination of military force and Ismaili missionary networks.

Al-Mustansir's reign in Cairo lasted 60 years, the longest of any Fatimid caliph, and his name appears on Ismaili-aligned issues across a remarkably wide geographic arc.
