Nara Narayan

A border tiff at Sala, just above Kaliabor escalated in 1546 with three step-brothers forging ahead into the Ahom kingdom, to meet with their deaths.

[5] He consolidated his alliance with the tribal groups, with the help of whom his father had established the kingdom and decreed that their religious practice should prevail north of the Gohain Kamal Ali.

The Treaty of Majuli was settled, which established the Koch hegemony in the Brahmaputra valley and extended the boundary in the east to Narayanpur.

At Langai in 1567, the Tripura king, Ananta Manikya, was killed along with 18,000 of his soldiers, and his brother was placed on the throne, however the authenticity of this account is highly doubted by scholars.

[8] Chilarai found a tougher foe in the Governor of Sylhet, allied with Suleiman Karrani then engaged in an expedition in Odisha; but he was killed after a prolonged three-day battle via a stratagem, and his brother was placed after extracting tribute from him.

[9] During the reign of Nara Narayan, varnasrama or fourfold caste system was introduced in Koch Behar by a Brahmin priest named Siddhantavagisa.

[10] This event was followed by the advent of Srimanta Sankardeva, along with his two disciples Madhavdeva and Damodardev in the mid 16th-century which accelerated the sankritisation of Koch royal family from their tribal belief system.

[13] In 1581 Raghu Deva, the son of his brother Shukladhvaj became the de facto ruler of the eastern part of his kingdom Koch Hajo, though under suzerainty of his uncle.

[14] Naranarayan employed eminent scholars and poets to translate the Bhagavad Gita, the Puranas, and the Mahabharata into Assamese, and to compile the treatise on arithmetic, astronomy, and grammar.
