Shah Khalil Allah III (Persian: شاه خليل الله سوم; 1740–1817) was the 45th Imam of the Nizari Ismaili Shia Islam community.
His upbringing in Mahallat, Iran began under the care of his uncle, Mirza Muhammad Bakir at the age of two years, and got rudiments of his formal education at home.
[2] The Imam was buried in the holy city of Najaf, Iraq, in a mausoleum that also contains the bodies of some of his relatives and descendants.
He was succeeded by his eldest son Shāh Ḥassan ‘Alī, who was the first Nizari Imam to use the title Aga Khan, a trend that continues to the present day.
Following the Imam's death, the Ismailis of Iran were in a strong enough position to finally come out publicly and cease their use of Taqiyya, which had been in force for over 500 years.
