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 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.
History
The early Dravidian movement led by E. V. Ramasami Periyar demanded an independent Dravidian State, which included all four Dravidian speaking states of South India. The movement failed to find support among other Dravidian people and had to be limited to Tamil Nadu. A new morphed ideology of Dravidian nationalism gained momentum within Tamil Nadu during the 1930s and 1950s.Dravidian Nationalism was thus based on three ideologies: dismantling of Brahmin hegemony; revitalization of the Dravidian Languages and social reform by abolition of existing caste systems, religious practices and recasting women's equal position in society.
By the late 1960s, the political parties who were espousing Dravidian ideology gained power within the state of Tamil Nadu. The Sixteenth Amendment of the Indian Constitution banned any party with sectarian principles from participating in elections. Faced with the new constitutional changes, Dravidian ideologues left the call for an independent Tamil homeland on the back burner. Subsequently, they aimed at achieving better co-operation between the states and claimed more autonomy for Tamil Nadu.
