Explanation:

Santhal Pargana

This region is mentioned as Kajangala in different ancient literatures specially in Buddhist literatures. It is mentioned that the Chinese monk-traveller Xuanzang (Hiuen Tsang) travelled from Champa (recent Bhagalpur) to Kajangala and then proceeded to Pundravardhana(recent Bangladesh) in the 7th century AD. He says that the northern limit of its territory (means Sahebganj) was not very far from the Ganges. The forests to the south had plenty of elephants. The people were straight forward, talented and devoted to education.
