Indo-Aryan is an ethno-linguistic term referring to the wide collection of peoples united as native speakers of the Indo-Aryan branch of the family of Indo-European languages. Today, there are slightly over approximately one billion native speakers of Indo-Aryan languages, most of them native to South Asia, where they form the majority. Their cultural influence, from early on in the 1st millennium AD, reached as far east as modern Cambodia and Vietnam (Khmer and Champa kingdoms) as well as Indonesia, where it survives in Bali and in the Philippines. Modern migration gave rise to Indo-Aryan minorities on most continents.
