Marigaon The district covers an area of 10,83,165 Bighas and 13 Lessas (1450.02 Sq. Kms). The district is bounded by the mighty Brahmaputra on the North, Karbi Anglong district on the South, Nagaon District on the East and Kamrup District on the West. The greater part of the district is an alluvial plain, criss-crossed with numerous rivers and water ways and dotted with many beels and marshes. The mighty Brahmaputra flows along with the northern boundary of the district.
Killing, Kollong and Kapili rivers flow through the southern part of of the district. The Killing meets the Kapili at the Matiparbat where from Kapili moves westward. The Kollong joins Kapili at the Jagi Dui Khuti Mukh and from here they jointly fall into the Brahmaputra. The general appearance of the district is extremely picturesque. On a clear day in the winter the view to the north is bounded by the blue ranges of the outer Himalayas, behind which snowy peaks glisten brightly in the sun, while to the west and the south of the district lie range upon range of lower hills, whose sides are covered with luxuriant vegetation of the tropical forest.
There are three Reserved Forest constituted under Assam Forest Regulation Act, 1891. These are Sunaikuchi, Khulahat, and Bura Mayong. There is also one wildlife Sanctuary, named Pabitara, which is famous for the Indian one horned Rhinoceros.
Morigaon Sadar Sub division is the only Sub-Division in the District. Before crteation of the Morigaon District in 1989, Morigaon Sub-Division was a Civil Sub-Division of the un-divided Nagaon District.
The history of Morigaon is obscure. One famous traditional ruler of the region was Arimatta whose history is shrouded in mystery. After Arimattas's death, Jongalbalahu, his son ruled over the region. Jongalbalahu was ultimately killed by the Kacharis with a bamboo spear near Kajalimukh.
The legend further goes on to say 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.
The writing of Bhimsingh throws some light on the history of present Morigaon town and its adjoining areas. This region was ruled independently by six rulers. During this time two princes from Darrang, Supradhvaj and Makardhvaj, fled from their homeland due to internal clash, by crossing the mighty Brahmaputra and they settled at Bahakajari. Later on, Supradhvaj married the daughter of Mangalsingh, the King of Baghara. Supradhvaj was then made the seventh king of the region, having an independent kingdom of his own.
During the days of Lachit Borphukan, another two princes from Darrang , Ram Singh and Bhimsingh crossed the Brahmaputra in search of plain lands. After Bhim Singh settled down, meanwhile, Ram Singh left for his home. Bhim Singh was not liked by the local people, hence, he left Brahmaputra and settled down near Mori Beel. This place came to known as Morigaon.
