Hamza ibn-'Ali ibn-Ahmad

Hamza ibn ‘Alī ibn Aḥmad (985- c. 1021) (Persian: Hamze Pesare Ali, literally Hamze Son of Ali ; حمزه پسر علی‎‎) (Arabic: حمزة بن علي بن أحمد) was an 11th-century Ismaili and founding leader of the Druze. He was born in Zozan in Greater Khorasan in Samanid-ruled Persia (modern Khaf, Razavi Khorasan Province, Iran).

Hamza is considered the founder of the Druze and the primary author of the Druze manuscripts.

After spending the first twenty years of his life in Samanid-ruled Persia, Hamza emigrated to Egypt and became known in the Fatimid Government as Hamza al-Fātimī "Hamza the Fatimid". He arrived in Cairo (modern Egypt) just as the Fatimid Caliph Tāriqu l-Ḥākim built the House of Knowledge, which became one of the main cultural centers of the Fatimid state. In a very short period of time, Hamza became a close associate of al-Ḥākim and the Caliph appointed him Head of Letters and Correspondence.

Hamza took as his headquarters the Raydan Mosque, which was located outside the walls of Cairo. This mosque became the center where Hamza organized a new missionary movement. In May 1017, al-Ḥākim issued a decree naming Hamza the imām of "the Monotheists" (al-Muwahhidūn) immediately after declaring the beginning of the Divine call. Hamza demonstrated brilliant leadership for four years under al-Ḥākim’s direction.

Al-Ḥākim granted Hamza the freedom to preach this new reformist doctrine openly. Public resistance to Hamza's teachings increased as he spoke against corruption, polygamy, remarriage of divorcees and other social customs as well as his theological disputes with other prominent Ismaeli leaders.
