Dravidian parties include an array of regional political parties in the state of Tamil Nadu, India, which trace their origins and ideologies either directly or indirectly to the Dravidian movement of Periyar E. V. Ramasamy. The Dravidian movement was based on the linguistic divide in India, where most of the Northern Indian, Eastern Indian and Western Indian languages are classified as Indo-Aryan, whereas the South Indian languages are classified as Dravidian. Dravidian politics has developed by associating itself to the Dravidian community. The original goal of Dravidian politics was to achieve social equality, but it later championed the cause of ending the domination of North India over the politics and economy of the South Indian province known as Madras Presidency (Madras Presidency of British India consisted almost all of today's Tamil Nadu State and parts of Andhra Pradesh). Thus Dravidian politics incorporates elements of Tamil Nationalism and has found support only in Tamil Nadu.
