Ambedkar dedicated his life to the removal of untouchability and the promotion of untouchables in society. From 1924 to the end of his life, he was the leader of the untouchable movement. He was certain that the nation's progress could not be realised unless untouchability was abolished first. According to Ambedkar, untouchability was linked to the abolition of the caste system, which could only be accomplished by removing religious notions from the system's base. As a result, as part of his critique of the caste system, he examined and criticised Hindu religious philosophy. He did it bravely, often in the face of orthodox Hindus' vehement objections. This paper focuses on Ambedkar's thoughts on social reform
