Haghani school (also Haqqani) is a Shi'i school of thought in Iran based in the holy city of Qom and formerly headed by Ayatollah Mohammad Taghi Mesbah Yazdi, an influential theologian. The Haghani Circle has its origin in the Haghani seminary, founded in 1964, which previously had been called Muntashiriya. After Ayatollahs Qoddusi and Beheshti, two of the leading members of the circle, were assassinated in 1981, the hawza changed its name to Shahidan Seminary (Martyrs Seminary).
