Role of B.R. Ambedkar in drafting Indian constitution has been immense. With the independence of India on 15th August 1947 the leadership of Indian national congress invited Dr Ambedkar to serve for the nation as the first law minister - which is gladly accepted. Few weeks later he was also appointed as the Chairman of the Constitution Drafting Committee, charged by the Assembly to write India`s new Constitution.

Many well-known scholars have defined the Indian constitution in their own way like Granville Austin has described the same 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 that was prepared by Dr B.R. Ambedkar also offered constitutional assurances and security for a wide range of civil liberties for individual citizens, which included freedom of religion, the elimination of untouchability and the banning of all types of discrimination. B.R. Ambedkar also worked for widespread financial and social rights for women society, and also won the support of Assembly for bringing in a system of job reservations in the Indian Civil Services, schools and colleges for members of planned castes and scheduled tribes, a system similar to positive action. Lawmaker`s of India wished to get rid of the socio-economic inequalities and be deficient in of opportunities for India`s miserable classes through this way. The Constitution of India was adopted on 26th November 1949 by the Constituent Assembly.

In 1951, B.R. Ambedkar at last submitted his resignation as a member of the cabinet, following the standing in parliament of his draft of the Hindu Code Bill that required explaining gender equality in the laws of inheritance, marriage and the economy.

In the year 1952, Dr Ambedkar independently contested an election to the lower house of parliament, the Lok Sabha, but lost the contest. He was appointed to the upper house, of parliament, the Rajya Sabha in March 1952 and would remain as member till death
