الحاكم بأمر الله
Throughout the Islamic Golden Age, the relatively tolerant societies of the various caliphates were still, on occasion, driven to enforce discriminatory laws against members of the Jewish faith. Examples of these and more extreme persecutions occurred under the authority of multiple, radical Muslim Movements such as that of the Fatimid Caliph Al-Hakim bi-Amr Allah in the 11th century, the Almohad Caliphate in the 12th century, and in the 1160s CE Shiite Abd al-Nabi ibn Mahdi who was an Imam of Yemen.
