Morigaon district is a district of Assam state with its administrative headquarters located at Morigaon town. The history of the Morigaon district is not very clear. The history of Arimatta, a famous traditional ruler of the region belonged to the Keot(Kaibarta) communityis full of vagueness as well. When Arimatta was died, his son named Jongalbalahu came to rule over the place. But after some time Jongalbalahu was killed by the Kacharis (a tribe) with a bamboo spear near Kajalimukh. Additionally, the legend also believe that Jongalbalahu to escape his pursuers submerged himself in Kollong River and emerge at Raha to quench his thirst and again dived here to emerge at Jagi. From this incident were derived the names of present day Raha and Jagi. A writer named Bhim Singh has threw some light on the history of the present day Morigaon town and its neighbouring areas. According to his writings during different periods of time the place was ruled by different rulers. At that there were time two princes from Darrang called Supradhvaj and Makardhvaj, who by crossing the mighty Brahmaputra fled from their native soil because of some internal clashes. Later they settled down at Bahakajari. Then Supradhvaj married the daughter of Mangalsingh, the King of Baghara. As a result Supradhvaj became the seventh king of the region. During the age of Lachit Borphukan, another two princes from Darrang called Ram Singh and Bhimsingh crossed the Brahmaputra river in order to search a plain land. Since Bhim Singh was disliked by the local people, hence, he left Brahmaputra and then settled down near the Mori Beel. Finally, this place became popularly known as Morigaon.
