Abu'l-Fath Khan Bakhtiari
Abu'l-Fath Khan Bakhtiari () was the Bakhtiari supreme chieftain ("ilkhani") of the Haft Lang branch. Biography. He was the governor of Isfahan at the time of the death of Nader Shah (r. 1736–1747) in 1747—the latters successors, Adil Shah, Ebrahim Shah, and Shahrokh Shah, continued to acknowledge Abu'l-Fath's post as governor of the city. When the Chahar Lang chieftain Ali Mardan Khan Bakhtiari and the Zand chieftain Karim Khan stormed the gates of Isfahan in May 1750—Abu'l-Fath and other prominent residents assembled to protect the fortress of the city, but agreed  to surrender and collaborate with them after Ali Mardan's reasonable proposals. Abu'l-Fath, together with Ali Mardan and Karim Khan, formed an alliance in western Iran under the cover of restoring the Safavid dynasty, appointing a 17 year old Safavid prince, Abu Turab, as a puppet ruler—on June 29, Abu Turab was declared shah, and assumed the name of Ismail III. Ali Mardan then took the title of "Vakil-e daulat" ("deputy of the state") as the head of the administration, while Abu'l-Fath maintained his post as governor of Isfahan, and Karim Khan was appointed commander ("sardar ) of the army, and was given the task of conquering the rest of Iran. However, a few months later, while Karim Khan was on a expedition in Kurdistan, the ambitious Ali Mardan had Abu'l-Fath deposed and killed.
