The Dravidians, or Dravidian peoples, are the ethnolinguistic groups native to South Asia who speak Dravidian languages, a language family separate from the Indo-European languages of northern India. There are about 250 million native speakers. The largest groups are the Telugus (about 95 million) and Tamils (about 85 million), followed by the Kannadigas, Malayalis and Gondis, and Telugu, Tamil, Kannada and Malayalam are all among India’s 22 scheduled languages.
Dravidian speakers make up most of the population of South India and northern and eastern Sri Lanka, and smaller communities such as Brahui speakers in Pakistan and Kurukh speakers in eastern India live farther north. Their deeper origins are still debated: they are regarded as indigenous to the Indian subcontinent, and many scholars link early Dravidian languages to the Indus Valley Civilisation. The term describes a language family and the peoples who speak it, not a single race or nation.
