In 1990, the National Front coalition government, led by Prime Minister V. P. Singh, implemented the recommendations of the Mandal Commission, which included 27% reservation for Other Backward Classes (OBC) candidates in government jobs and public sector undertakings.
The Mandal Commission, the Socially and Educationally Backward Classes Commission (SEBC), was established in India in 1979 by the Janata Party government under Prime Minister Morarji Desai to "identify the socially or educationally backward classes" of India.
It was headed by B.P. Mandal, an Indian parliamentarian, used eleven social, economic, and educational indicators to consider the question of reservation for people to prevent caste discrimination, and to determine backwardness.
