Passage: Upon India's independence on 15 August 1947, the new Congress-led government invited Ambedkar to serve as the nation's first Law and Justice Minister, which he accepted. On 29 August, he was appointed Chairman of the Constitution Drafting Committee, and was appointed by the Constituent Assembly to write India's new Constitution.Ambedkar was a wise constitutional expert, he had studied the constitutions of about 60 countries. Ambedkar is recognised as the "Father of the Constitution of India". In the Constitution Assembly, a member of the drafting committee, T. T. Krishnamachari said, "(...) it happened ultimately that the burden of drafting this constitution fell on Dr. Ambedkar and I have no doubt that we are grateful to him for having achieved this task in a manner which is undoubtedly commendable."Granville Austin 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 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 and Other Backward Class, 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.
