The Koch rule in Cachar was the product of military adventurism. The Koch state experienced a series of segmentation. The Koch king Naranarayana extended his territorial expansion with the help of his able brother chilarai. But later on they failed to cheek their growth. They also failed to sustain their own structure. The Koch principality in Cachar emerged as a military colony in a conquered tract. But it soon lost its military character. They patronized the Brahmins and temples. The society was organized on hierarchical hereditary basis. Soon later, the Dimasas emerged stronger and gradually extended their boundary to the Koch territories in Cachar. In Such a situation, the Koch Raja in Cachar was bound to look upon his Dimasa counterpart as a protecting power. The fact that the last Raja had no male successor and the two principalities merged in to one through a matrimonial alliance. It recognized the status of the Dimasa Raja as the ruler of Cachar (Khaspur).
