Ridwan ibn Walakhshi

Ridwan ibn Walakhshi (Arabic: رضوان بن ولخشي) was the vizier of the Fatimid Caliphate in 1137–1139, under Caliph al-Hafiz li-Din Allah. He was a Sunni military commander, who rose to high offices under caliphs al-Amir bi-Ahkam Allah and al-Hafiz. He participated in the coup of Kutayfat, which in 1130–1131 briefly overthrew the Fatimid dynasty, serving as gaoler of the future caliph al-Hafiz. Under al-Hafiz he rose to the powerful position of chamberlain, and emerged as the leader of the Muslim opposition during the vizierate of the Christian Bahram al-Armani in 1135–1137, when he served as governor of Ascalon and the western Nile Delta.

In February 1137, he rose in revolt against Bahram, drove him from Cairo, and was in turn appointed to the vizierate with the title of "Most Excellent King" (al-malik al-afḍal) denoting his ambitions and status as a de facto monarch in his own right. His tenure lasted two years and five months, and was marked by a reorganization of the government and by a persecution of Christian officials, who were replaced by Muslims, as well as the introduction of restrictions on Christians and Jews. Ridwan also planned to depose al-Hafiz and the Fatimid dynasty in favour of a Sunni regime headed by himself, but the Caliph raised the army and the people of Cairo against him, forcing him to flee his post in June 1139. Ridwan rallied his followers and tried to capture Cairo, but was defeated and had to surrender.

He remained in confinement in the palace until he managed to escape by digging a tunnel in May 1148. Ridwan once again raised his followers into revolt, and managed to enter Cairo, but was assassinated shortly after by soldiers of the Caliph's bodyguard.
