Nagaon [nɔgaʊ zila] is an administrative district in the Indian state of Assam. At the time of the 2011 census it was the most populous district in Assam, but since Hojai district has split that title was lost to Dhubri.It became a municipality in the year 1893. The eastern, western, and southern fringes of the newly organized district were once ruled by different small feudal kings or their agents. An extensive and undulating plain intersected bby big and small hills and rivers- the geography of the segments determined who their masters ought to be. The residual effects of the rule of the Bhuyans were imaginatively utilized and reorganized by Momai Tamuli Barbarooah, an intrepid officer of the Ahom King Pratap Singa in the first half of the Seventeenth Century. This area, until then, was more of strategic than administrative concern. It was a newly organized village system- hence called “Nagaon”, Na meaning new.
