Anna University is a technical college in Tamil Nadu, India. The main campus is in Guindy, Chennai. The Government of Tamil Nadu established Anna's University of Technology on September 4, 1978 through Tamil Nadu Act 30 of 1978. The new university was formed from the former faculty of engineering and technology of the University of Madras and consisted of four institutes: Madras Institute of Technology, College of Engineering, Guindy, Alagappa College of Technology and School of Architecture and Planning. In 1982, the current name name "Anna University" was adopted.
In 2001, under the Anna University Amendment Act of 2001, the university became an affiliated university, taking under its wing all engineering schools in Tamil Nadu. This included six government engineering colleges, three privately subsidized government institutions, and 426 self-funded universities. On February 1, 2007, as a result of a Tamil Nadu Government decision, the university was divided into six university constituent universities: Anna University, Chennai, Anna University of Technology, Chennai, Anna University of Technology, Tiruchirappalli, Coimbatore, Anna Tirunelveli University of Technology and Ana, Madurai University of Technology. The institutes were formally created in 2010. On September 14, 2011, a bill was approved to merge universities. The merger became final in August 2012. In 2011 and 2012 the constituents were merged back to a single affiliated university and the four regional universities continue to function as regional university offices.
