Parni

The Parni (/ˈpɑːrnaɪ/; Ancient Greek: Πάρνοι, Parnoi) or Aparni (/əˈpɑːrnaɪ/; Ἄπαρνοι, Aparnoi) were an east Iranian people of the Ochus (Ancient Greek: Ὧχος Okhos) (Tejen) River valley, southeast of the Caspian Sea. 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.

There is no unambiguous evidence of the Parnian in native Iranian language sources,^cf. and all references to these people comes from Greek and Latin accounts. In these accounts, which are not necessarily contemporaneous, it is difficult to unambiguously identify references to the Parni due to inconsistency of Greek/Latin naming and transliteration, and/or the similarity to names of other tribes such as the Sparni or Apartani and the Eparnoi or Asparioi. It may also be that the Parni are related to one or more of these other tribes, and that "their original homeland may have been southern Russia from where they emigrated with other Scythian tribes."
