what is mandal commission?plz explain.

The Mandal Commission was established in India in 1979 by the Janata Party government under Prime Minister Morarji Desai with a mandate to "identify the socially or educationally backward." It was headed by Indian parliamentarian Bindheshwari Prasad Mandal to consider the question of seat reservations and quotas for people to redress caste discrimination, and used eleven social, economic, and educational indicators to determine backwardness. In 1980, the commission's report affirmed the affirmative action practice under Indian law whereby members of lower castes (known as Other Backward Classes (OBC) and Scheduled Castes and Tribes) were given exclusive access to a certain portion of government jobs and slots in public universities, and recommended changes to these quotas, increasing them by 27% to 49.5%. In a historical context, the Mandal Commission was one of the many aspects of the social justice movement in post-Independence India. Mobilization on caste lines had followed the political empowerment of ordinary citizens by the constitution of free India that allowed common people to politically assert themselves through the right to vote.
