Gohain Kamal Ali
Gohain Kamal Ali, was a road that connected the capital of the Koch kingdom and Narayanpur in Lakhimpur district in Assam. This was constructed under the supervision of Gohain Kamal, the step-brother of Nara Narayan the king, and was completed in 1547. This was the road that the Koch general Chilarai used soon after for his invasion of the Ahom kingdom, and attacked the Ahom fort at Pichala, which was not a success, but a later movement in 1562 was greatly successful.
This road has also been of historical significance because it formed the boundary between the tribal region to the north of it and the orthodox region to the south of it. In 1562 Naranarayan encamped at Chandikabehar, Mangaldai, he demarcated the region north of the road as where the Koch and the Mech people were to follow the tribal customs, and region south where Brahmanic rites were to be followed. In later years, this road formed the southern boundary of the Assam Duars that formed a buffer zone between the political powers in the plains of Brahmaputra valley and the hills of Bhutan.
