In the context of 19th-century physical anthropology and scientific racism, the term "Aryan race" came to be misapplied to all people descended from the Proto-Indo-Europeans – a subgroup of the Europid or "Caucasian" race, in addition to the Indo-Iranians (who are the only people known to have used "Arya" as an endonym in ancient times). This usage was considered to include most modern inhabitants of Australasia, the Caucasus, Central Asia, Europe, Latin America, North America, Siberia, South Asia, Southern Africa, and West Asia. Such claims became increasingly common during the early 19th century, when it was commonly believed that the Aryans originated in the south-west Eurasian steppes (present-day Russia and Ukraine).
