What is "aorsi"

The Aorsi, also or Aorsoi, known in Greek sources as the Aoirsoi, were an ancient Iranian people of the Sarmatian group, who played a major role in the events of the Pontic Steppe from the 1st century BC to the 1st century AD.

They are often regarded as connected to the contemporaneous Eurasian steppe state of Yancai (or Yentsai) mentioned in ancient Chinese records. The Alans, first mentioned by Middle Eastern and European scholars in the 1st century AD, are regarded as successors of the Aorsi.
