Aryan, or Arya, is a term originating from the ethno-cultural self-designation of the Indo-Iranians. It stood in contrast to nearby outsiders, whom they designated as non-Aryan. In ancient India, the term was used by the Indo-Aryan peoples of the Vedic period both as an endonym and in reference to a region called Aryavarta, where their culture emerged. Similarly, according to the Avesta, the Iranian peoples used the term to designate themselves as an ethnic group and to refer to a region called Airyanem Vaejah, which was their mythical homeland. The word stem also forms the etymological source of place names like Alania and Iran.
