Lakhimpur district is a district of Assam state with its administrative headquarters located at North Lakhimpur town. The natives of the district believe that the district got its name “Lakhimpur” from the word “Lakshmi”, the goddess of prosperity. Here paddy is locally called as “Lakhimi”. On the other hand the meaning of the word “pur” is “full”. Therefore both the terms Lakhimi and pur together means a place full of paddy or the place where paddies are grown abundantly. The second meaning is 'The City of Wealth and Prosperity'. Some others believe that the term Lakhimpur is originated from Lakhsmi Devi, the mother of Bhuyan Raja who was the descendent of King Arimatta. The name Lakhimpur was taken from the name "Lakshmipur" which was given by the Chutiya king called Lakshminaryan who ruled this region during the 15th century. After sometime, it was changed to Lakhimpur by the Baro-Bhuyans, when they were made feudal lords of the region by the Ahoms after the downfall of the Chutiya kings and was kept in memory of the land (in present-day Darrang district), which they lost to the Koch kingdom. According to the Lakhimpur District Gazette (1976:4), the then Governor General had issued a proclamation on July, 1839 through which he declared the place of Lakhimpur as a separate district. On 2nd October, 1971 the district was divided into two sub divisions namely Dhemaji and North Lakhimpur.
