Gopal Baba Walangkar, also known as Gopal Krishna, ( 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 monthly journal Vital-Vidhvansak, targeted at the Brahmanical Orthodoxy.
