In the twelfth century, Lingayatism emerged in northern Karnataka as a protest against the rigidity of the prevailing social and caste system. Leading figures of this movement were Basava, Akka Mahadevi and Allama Prabhu, who established the Anubhava Mantapa which was the centre of all religious and philosophical thoughts and discussions pertaining to Lingayats. These three social reformers did so by the literary means of ""Vachana Sahitya"" which is very famous for its simple, straight forward and easily understandable Kannada language. Lingayatism preached women equality by letting women wear "Ishtalinga" i.e. Symbol of god around their neck. Basava shunned the sharp hierarchical divisions that existed and sought to remove all distinctions between the hierarchically superior master class and the subordinate, servile class. He also supported inter-caste marriages and Kaayaka Tatva of Basavanna. This was the basis of the Lingayat faith which today counts millions among its followers.
