Rajasthan was the first Indian state to introduce the Panchayati Raj system on October 2, 1959, in Nagaur district. This system was implemented following the recommendations of the Balwant Rai Mehta Committee (1957), which advocated for democratic decentralization at the grassroots level. The Panchayati Raj system ensures local self-governance in rural areas and enhances the role of the people in decision-making processes concerning their welfare.
