<P> R.N. Dogra the Chief Engineer of Chandigarh persuaded Prof M.S. Thacker, then Member of the Planning Commission to set up an IIT at Delhi on the ground that the country was divided into five regions, and all but the North had an IIT each . It was done on the basis of the logic that Uttar Pradesh and Madhya Pradesh constituted the Central Region . Hence, officially, Kanpur was located in the Central Region, not the North . This led to the establishment of IIT Delhi in 1961 . The Indian Institutes of Technology Act was suitably amended to reflect the addition of new IITs . </P> <P> After the establishment of IIT in Delhi, there was a long gap in any notable development in the history of IITs . However, in the beginning of the 1990s, widespread student agitations in Assam led to Prime Minister Rajiv Gandhi promising another IIT in Assam . Rajiv Gandhi agreed to it on the spot considering it a minor request of IIT although eventually it cost over Rs 1,500 crore . The IIT Guwahati campus was established in 1994 and started functioning in 1995 . In the beginning of the 21st century, Dr Murli Manohar Joshi (the Education Minister of India) made University of Roorkee into an IIT, making IIT Roorkee the newest IIT but the oldest institution amongst the seven in 2001 . </P> <P> Establishment of the eight new IITs began with decision of the cabinet, which was announced by the Minister of Human Resource Development (MHRD), Arjun Singh, on 28 March 2008 that the government planned to establish more IITs, Indian Institutes of Management (IIMs) and Central Universities across the country . Six IITs at Bhubaneswar, Gandhinagar, Hyderabad, Jodhpur, Patna and Ropar began functional from 2008 while other two at Indore and Mandi commenced their sessions from 2009 . </P> <P> In order to establish more IITs in India, MHRD constituted Professor SK Joshi Committee in 2003 and Anand Krishnan Committee in 2005 to recommend names of existing institutes that had the potential of being converted into an IIT institute, both of which had recommended for the conversion of the IT - BHU into an Indian Institute of Technology (IIT). On 17 July 2008, the government of India issued a press release granting "In principle approval for taking over the Institute of Technology, Banaras Hindu University--a constituent unit of the Banaras Hindu University, a Central University, its conversion into an Indian Institute of Technology and integrating it with the IIT system in the country ." After the approval of BHU Executive Council, a Bill was introduced on 4 August 2010 a bill seeking to amend the Institutes of Technology Act 1961 to declare IT - BHU as an IIT . The Bill was eventually signed by the President of India on 20 June 2012 and notified in the gazette on 21 June . The Central Government released a notification on 29 June that as per the Act, the transformation process was complete and the erstwhile IT - BHU was renamed as Indian Institute of Technology (BHU) Varanasi . </P>
