Al-Hakim (996-1021). Fatimid Caliph who ruled the Muslim world from Egypt, waging a relentless campaign to convert his Christian and Jewish subjects to Islam. In 1016, convinced of his own divinity, he led his followers out of Islam into a new religion, whose members are known as Druze. He disappeared in Cairo in 1021. Non-Druze believe he was murdered. Druze believe he went into hiding and will return to redeem and rule the world.
