Kisan Baburao Hazare (Marathi: ???? ??????? ?????) (born 15 January 1940), popularly known as Anna Hazare (Marathi: ????? ?????), is an Indian social activist who is especially recognised for his contribution to the development of Ralegan Siddhi, a village in Parner taluka of Ahmednagar district, Maharashtra, India and his efforts for establishing it as a model village, for which he was awarded the Padma Bhushan by the government of India in 1992.
He is also the winner of the 2011 Rabindranath Tagore International Peace Prize, with a Rs.10 million honorarium, awarded by the Indian Institute of Planning and Management.
On 5 April 2011, Hazare started a 'fast unto death' to exert pressure on the government of India to enact a strong anti-corruption act as envisaged in the Jan Lokpal Bill, a law that will establish a Lokpal (ombudsman) that will have the power to deal with corruption in public offices. The fast led to nation wide protests in support of Hazare. The fast ended on 9 April 2011, the day after all of Hazare's demands were agreed by the government of India and the government issued a gazette notification on the formation of a joint committee (of government and civil society representatives) to draft an effective Lokpal Bill.
