Dr Ambedkar's role in the cause of social emancipation has been researched and written about extensively. His part in the drafting of the Indian Constitution between 1946 and 1950 has also received considerable attention. In The Foresighted Ambedkar, Anurag Bhaskar argues that India's Constitution was drafted not just between 1946 and 1950 but over the course of four decades. Dr Ambedkar was the only person to have been involved at all the stages related to the drafting of the Indian constitutional document since 1919. These stages bear the imprint of his contribution and role.
