الحاكم بأمر الله
The Druze believe the imam Al-Hakim bi-Amr Allah went into the Occultation after he disappeared in 1021 followed by the four founding Da'i of the Druze sect including Hamza ibn-'Ali ibn-Ahmad leaving the leadership to a fifth leader called Baha Al-Din. The Druze refused to acknowledge the successor of Al-Hakim as an Imam but accepted him as a Caliph. The faith further split from Ismailism as it developed unique doctrines which often classes it separately from both Ismailism and Islam, these include the belief that Al-Hakim bi-Amr Allah was God incarnate.
