India is divided into many
endogamous groups i.e.
castes and sub-castes, as a result of social stratification and presence of untouchability. During the
British Raj, some methods for upliftment of these depressed classes were introduced by the British, progressive thinkers and
Hindu reformers. These included reservations in the legislature and in government jobs. After independence, the
Indian constitution introduced provisions for reservations for the
Scheduled Castes and Tribes (SC/ST) in government institutions, to give a fair representation to the weakest sections of society i.e. Dalits and Adivasis. 22.5% of the seats (SC- 15%, ST- 7.5%) in higher education institutes and
public sector undertakings at both state and central level were set-aside for them. Uplifting the SC/ST's representation par with the upper castes has not yet been achieved. In 1989, the then-
Prime Minister of India V. P. Singh accepted and implemented nationwide the proposals of the
Mandal Commission, which had been established by the
Morarji Desai-led
Janata Party government in 1979. The proposals of this commission recommended 27% reservation for
Other Backward Classes (OBCs) in public sector undertakings and state-level educational institutions. OBC's were a group of castes which fell in-between the upper castes and Dalits; they were historically not oppressed and socially boycotted as the Dalits and Adivasis, but were still socially, educationally and economically backward compared to the upper castes. After the
State Assembly elections in Tamil Nadu, Kerala, Puducherry, Assam and West Bengal, the Union Minister of Human Resource Development,
Arjun Singh promised to reserve 27% seats for
Other Backward Classes in
All India Institute of Medical Sciences (AIIMS),
Indian Institutes of Technology (IITs),
National Institutes of Technology (NITs),
Indian Institutes of Management (IIMs),
Indian Institute of Science (IISc) and other central institutions of higher education. The Constitution (93rd Amendment) Act 2005 that was introduced by the
First Manmohan Singh ministry, granted a 27% reservation for Other Backward Classes in all Central Government institutions. ==Text of 93 Amendment==
