Al-Zahir li-I'zaz Din Allah

Abū al-Ḥasan ʿAlī ibn al-Ḥākim, known by his regnal name al-Ẓāhir li-Iʿzāz Dīn Allāh, was born on June twentieth, one thousand five. He ascended to the caliphate as the seventh leader of the Fatimid dynasty in the year one thousand twenty-one, following the mysterious disappearance of his father, al-Hakim bi-Amr Allah.

During his reign, which lasted until June thirteenth, one thousand thirty-six, al-Ẓāhir was recognized not only as a sovereign but also as an imam and caliph. His title, which translates to 'He Who Appears Openly to Strengthen the Religion of God,' reflects his commitment to the Fatimid ideals and the promotion of the Ismaili branch of Islam.

Al-Ẓāhir's leadership was marked by efforts to consolidate power and maintain the stability of the Fatimid state. His tenure is noted for its religious significance and the challenges faced during a period of political intrigue and shifting allegiances within the empire.
