The Most Special Flags Of Iran

  Before Arsaces I founded the Arsacid Dynasty, he was the chieftain of the Parni, an ancient Central Asian tribe of Iranian peoples and one of several nomadic tribes within the confederation of the Dahae. The Parni most likely spoke an eastern Iranian language, in contrast to the northwestern Iranian language spoken at the time in Parthia. The latter was a northeastern province, first under the Achaemenid Empire, and then the Seleucid Empire. After conquering the region, the Parni adopted Parthian as the official court language, speaking it alongside Middle Persian, Aramaic, Greek, Babylonian, Sogdian, and other languages in the multilingual territories they would conquer.
