Dr. B.R. Ambedkar, an influential political thinker and social revolutionary, advocated for a social democracy that addressed the caste system and emphasized equality, liberty, and fraternity. He criticized the hierarchical structure of Hindu society, which perpetuated inequalities, and argued for the need to integrate social, economic, and political reforms to achieve true democracy. Ambedkar's vision extended beyond mere political governance, emphasizing the moral and ethical dimensions necessary for a just and equitable society.
