The Indo-Iranian peoples, also known as Ā́rya or Aryans from their self-designation, were a group of Indo-European speaking peoples who brought the Indo-Iranian languages to major parts of Eurasia in waves from the first part of the 2nd millennium BC onwards. They eventually branched out into the Iranian peoples and Indo-Aryan peoples.
