Narayanpur, originally known as Bor-Narayanpur (great Narayanpur) is a historical place since Ahom Kingdom. Narayanpur was earlier known as Bor-Nararayanpur. It was extended up to the Kolabari region of Sonitpur district. Various history writers had different views regarding the origin of the place as well as the origin of its name. Archeologist Raja Ram Mohan Roy in this book “The background of Assamese Culture”, has described Narayanpur as a temporary capital of the Kalita King Satyanarayan. According to J. P. Wade, “Narayanpur is thirty miles in length and fifteen miles in breadth. This district is situated on the bank of Pichala river and Colabari of Zokai chook.” Some others have the view that Koch King Naranarayan used this place as a garrison, that’s why the name became Narayanpur. The Tai Khamtis, a tribe belonging to the great Tai race, migrated to Assam in the middle part of 18th century. They have their own script and a well developed language including innumerable literary works.
History says that Narayanpur was a part of Bor-Asom. But this place had been continuously in influence of Aryan Culture. In the prehistoric era, Narayanpur was believed to be ruled by Ban Roja.
Many ancient idols of Hindu Gods and Goddesses were found in the different parts of Narayanpur. It proves the existence of highly civilized society in ancient times in this region
