Upon India’s independence on 15 August 1947, the new Congress-led government invited Ambedkar to serve as the nation’s first law minister, which he accepted. On 29 August, Ambedkar was appointed Chairman of the Constitution Drafting Committee, charged by the Assembly to write India’s new Constitution.

Granville Austin has described the Indian Constitution drafted by Ambedkar as ‘first and foremost a social document’. … ‘The majority of India’s constitutional provisions are either directly arrived at furthering the aim of social revolution or attempt to foster this revolution by establishing conditions necessary for its achievement.

The text prepared by Ambedkar provided constitutional guarantees and protections for a wide range of civil liberties for individual citizens, including freedom of religion, the abolition of untouchability and the outlawing of all forms of discrimination.Ambedkar argued for extensive economic and social rights for women, and also won the Assembly’s support for introducing a system of reservations of jobs in the civil services, schools and colleges for members of scheduled castes and scheduled tribes, a system akin to affirmative action. India’s lawmakers hoped to eradicate the socio-economic inequalities and lack of opportunities for India’s depressed classes through these measures. The Constitution was adopted on 26 November 1949 by the Constituent Assembly.
