The Massagetae or Massageteans, also known as Sakā Tigraxaudā or Orthocorybantians, were an ancient Eastern Iranian Saka people who inhabited the steppes of Central Asia and were part of the wider Scythian cultures. The Massagetae rose to power in the 8th to 7th centuries BCE, when they started a series of events with wide-reaching consequences by expelling the Scythians out of Central Asia and into the Caucasian and Pontic Steppes. The Massagetae are most famous for their queen Tomyris's alleged defeating and killing of Cyrus, the founder of the Persian Achaemenid Empire.
The Massagetae declined after the 3rd century BCE, after which they merged with some other tribes to form the Alans, a people who belonged to the larger Sarmatian tribal confederation, and who moved westwards into the Caucasian and European steppes, where they participated in the events of the Migration Period.
