Dravidian nationalism

Dravidian nationalism, or Dravidianism, developed in Madras Presidency which comprises the four major ethno-linguistic groups in South India. This idea was popularized during the 1930s to 1950s by a series of small movements and organizations that contended that the South Indians (Dravidian people) formed a racial and a cultural entity that was different from the North Indians. Dravidianists have claimed that the Brahmins and other upper castes were originally Aryan migrants from outside of India, and that they imposed their language, Sanskrit, religion and heritage on the Dravidian people. The claim was based on a hypothesis floated first during colonial times, popularized by Max Mueller, which is now described a myth by most present-day historians, based on modern DNA evidence studies.
