Gopal Baba Walangkar, also known as Gopal Krishna, (ca. 1840-1900) is an early example of an activist working to release the untouchable people of India from their historic socio-economic oppression, and is generally considered to be the pioneer of that movement. He developed a racial theory to explain the oppression and also published the first journal targeted at the untouchable people. Walangkar claimed that "high-caste people from the south were 'Australian–Semitic non-Aryans' and African negroes, that Chitpavan Brahmans were 'Barbary Jews', and that the high-caste Marathas' forebears were 'Turks'". In 1888, Walangkar began publishing the monthly journal titled Vital-Vidhvansak (Destroyer of Brahmanical or Ceremonial Pollution), which was the first to have the untouchable people as its target audience.
