The Azadan (Middle Persian: āzādān, Parthian: āzātān; meaning "free" and "noble") were a class of Iranian nobles. They are probably identical to the eleutheroi ("the free") mentioned in Greek sources to refer to a group of Parthian nobles. According to the 1st-century Romano-Jewish historian Josephus (died 100 AD), the Parthian army led by prince Pacorus I during the invasion of Judea consisted of members of the eleutheroi. The Kingdom of Armenia adopted the same hierarchy as that of the Parthians, which included the azadan class (azat), which was used to label the Armenian middle and lower nobility. The name of the Georgian nobility, Aznauri, also corresponded to that of azadan. A class of azadan are also attested in Sogdia, an Iranian civilization located in Central Asia.
