Indo-Iranian peoples are a linguistic group consisting of the Indo-Aryan, Iranian, Dardic and Nuristani peoples; that is, speakers of Indo-Iranian languages, a major branch of the Indo-European language family. The Proto-Indo-Iranians are commonly identified with the descendants of the Proto-Indo-Europeans known as the Andronovo culture and their homeland with an area of the Eurasian steppe that borders the Ural River on the west, the Tian Shan on the east. The term Aryan has generally been used historically to denote the Indo-Iranians because Arya is the self designation of the Indo-Iranian languages and their speakers, specifically the Iranian and the Indo-Aryan peoples, collectively known as the Indo-Iranians. Some scholars now use the term Indo-Iranian to refer to this group, while the term "Aryan" is used to mean "Indo-Iranian" by other scholars such as Josef Wiesehofer.
