Koch Kingdom

Bishwa Singha (1515-1540) laid the foundation of the Koch dominion over Kamata kingdom in the early part of the 16th century and established his capital in Cooch-Bihar. He was succeeded by his son Malladeva who took the name Naranarayana. His brother Sukladhvaj became his commander-in-chief. He was also called '' or 'Kite

King' because of his ability to attack the enemy like a Chila (hawk or Kite). Naranarayan's rule was the most glorious epoch of Koch kingdom. It was during his reign that the Ahoms suffered defeat in 1562. Chilarai also annexed the Kachari kingdom, Manipur, Tripura, Jayantia and Srihatta and extended its boundaries. Then again there was a battle with the Nawab of Gour. During that time Chilarai was attacked by small-pox and died on the banks of the Gangas.

Naranarayan died in 1584 after a reign of nearly fifty years (1540-1584). During his rule, the power of the Koch kings reached its zenith. Naranarayan's rule is remarkable, for it was during his reign that the and culture flourished, which was inaugurated by Srimanta Sankardeva. After the death of Naranarayan, the Koch kingdom was not able to retain its glory. Consequently the Afghans and the Mughals took advantage and in 1615, the Koch kingdom was annexed to the .

Kachari Kingdom The early part of the 13th century saw the rise of the Kachari kingdom, one of the ancient races of Assam. The powerful kings of the Kachari Kingdom were Jashanarayan, Pratapnarayan, Jamradwaj and Govindchandra. The Kacharis claim descent from Ghatotkacha, the son of Bhima. Towards the end of the 15th century the Kacharis had to surrender their capital Hidimbapur (now Dimapur) and the areas adjoining it to the Ahoms.

The third and the final invasion of the Kachari kingdom took place in 1803, when their king Chandra refused to send back the Moamarias to the Ahom king. The last king of the Kachari kingdom was Gobind Chandra (1813-1830).

Jayantia Kingdom Jayantia was a matriarchal race which had established their kingdom in and around Jayantia hills. Dhanamanik and Jashamanik were the powerful kings of the Jayantia Kingdom. They forged matrimonial relations with the Ahoms and fought alongside during the invasion of the Mughals. One of their rulers, Jashomatta Rai was the contemporary of the Ahom king Nariya Raja (1644-1648). He claimed back the possession of Dimoria, Gobha, Nellie and Khola principalities which led to the souring of the relations between the Jayantias and Ahoms. Bijaynarayan was the last Jayantia ruler after whom the kingdom passed into the hands of the British along with the Ahom kingdom.
