Koch Hajo

Koch Hajo was the eastern half of the divided Koch kingdom, lasting a single generation before the Mughals annexed it in 1614 and inherited its frontier with the Ahoms.


A short-lived partition

On Nara Narayan's death the kingdom was divided: his son took the western portion as Koch Bihar, and Chilarai's son Raghudev the eastern, called Koch Hajo. The two halves were immediately hostile, and each sought outside support — Koch Bihar from the Mughals, Koch Hajo from the Ahoms and then also from the Mughals.

Parikshit Narayan was defeated by a Mughal expedition in 1614 and the territory annexed to the empire.

The consequence was strategic and lasting: the Mughal frontier now met the Ahom kingdom directly, and the wars that followed ran for sixty years, ending with the Ahom victory at Saraighat in 1671 under Lachit Barphukan — a river battle on the Brahmaputra that halted Mughal expansion into the northeast permanently, and that remains the central episode of Assamese historical memory.
