The Nishan-e Aqdas (Imperial Order or Most Sacred Order) was an Imperial Iranian Order founded in 1870 by the Qajar Shah of Iran Nassereddin. There were three classes, with two different styles for Iranians (Sardar) and foreigners (Nishan). The Order was dissolved upon the collapse of the Qajar dynasty.
