The Medes or Medians were a group of Indo-Iranian-speaking people from central Asia who migrated westwards and entered northern Iran around the end of the 2nd millennium BCE. They settled in the highlands of Zagros (Zagreus in Greek) and, by the end of the 7th century BCE, founded the kingdom of Media (Mada in Old Persian).
