The Order of the Crown (Persian: نشان تاج, Nishan-i-Taj) was founded in 1913 (1332 AH)[1] by Shah Ahmad Shah Qajar before his coronation as the highest dynastical and state order.

Until 1926 it existed in two classes (with breast star and sash for both).

The 1st class had a collar (neck chain with badge as a pendant) reserved for the Shahanshah and the Crown-Prince.

The Order was preserved in Iran after the fall of the Qajars.

The first Shah from the Pahlavi dynasty reformed the order at the end of the year in 1938/39.
