Parni

The Parni (; Ancient Greek: Πάρνοι, Parnoi), Aparni (; Ἄπαρνοι, Aparnoi) or Parnians were an East Iranian people who lived around the Ochus (Ancient Greek: Ὧχος Okhos) (Tejen) River, southeast of the Caspian Sea in Central Asia. It is believed that their original homeland may have been what is now southern Russia in Eastern Europe, from where they emigrated with other Scythian tribes. The Parni were one of the three tribes of the Dahae confederacy. In the middle of the 3rd century BCE, the Parni invaded Parthia, "drove away the Greek satraps, who had then only just acquired independence, and founded a new dynasty", that of the Arsacids.
