Dimapur is said to have been named after Hidimba. Dimapur is a corruption of Hidimbapur, meaning the city of Hidimba of Mahabharata, who is believed to be the progenitor of the Kacharis. Later Hidimbapur devolved to Dimbapur and then finally to Dimapur.
While another popular belief is that Dimapur etymologically is named after Dimasas, where Dimasa and pur (which means river) is amalgamated. Dimapur etymologically transtates to “City of the Dimasas”.
Ahom Buranjee chronicles mentioned Dimapur as “Che-Dima” meaning city of Dimasas. By the 13th century the Dimasa Kachari Kingdom extended along the southern banks of Brahmaputra river, from Dikhow river to Kallang river and included the valley of Dhansiri and present-day Dima Hasao district. According to the Buranjis, the Dimasa Kachari settlements to the east of Dhansiri withdrew before the Ahom advance. The Sutiya Kingdom existed further east and the Kamata Kingdom to its west.
Dimapur is the largest city in Nagaland, India. In the Middle Ages, it was the capital of the Dimasa Kachari rulers. In the heart of the town there is an old relic of the Dimasa Kachari Kingdom which speaks about the once prosperous era but is now in ruins due to non attention and neglect.
