During 17^th century the trade route to Kolhan was unsafe due to attack of which tribe?

Solution (By Examveda Team)

Kolhan was the Ho tribe's epicentre. The hos were a freedom-loving and warrior class who were used by the rulers of Singhbhum, who employed them in their struggle against their own rivals. The trade route through Kolhan became insecure as a result of the ho attacks on nagvanshi districts.
