1/2 Dinar - al-Mukarram Ahmad Vassal of Fatimid - Aden mint

The Sulayhid dynasty of Yemen held power as Fatimid vassals, and their coinage reflects that dependency directly — Fatimid caliph names appear alongside those of the local Sulayhid ruler as a formal declaration of subordination to Cairo. Al-Mukarram Ahmad was the last significant male ruler of the line; by this point, real political authority had largely passed to his wife, Arwa al-Sulayhi, who would govern from Jibla for decades after his incapacitation by illness.

Aden's mint was active precisely because the city's position at the mouth of the Red Sea made it the commercial hinge of Indian Ocean trade. Half-dinar fractions served that merchant economy well.
