Misinai states that of this gradual process of conversions (often accompanied by Arabization), the majority were forcibly converted during the Fatimid era under the reign of Caliph al-Hakim who was crowned at the age of 11, and reigned from the years 996 to 1021. Due to his young age, in practice, it was his ministers who wielded the actual power behind the throne for some time. They gave the young Caliph power to influence religious matters only, and appointed him as Imam.
