Following the ascension of the Pahlavi dynasty in 1925, Reza Shah ordered a group of Iranian jewelers, under the supervision of Haj Serajeddin Javaheri, to create a new crown to replace the Kiani Crown, which had been used by the Qajar dynasty. Inspiration for the new design was drawn from paintings and historical references to crowns used during the Sassanid Empire, which had ruled Persia from 224 to 651 AD.
