Arrival at Raj Mahal Hills: Around the 1780s, Santhals migrated to the Raj Mahal hills due to land scarcity and the pursuit of a better life. Employment by Zamindars: Zamindars engaged them to reclaim land and expand agriculture, a primary incentive for their relocation. British Encouragement to Settle: British officials encouraged Santhals to inhabit and cultivate the jungle mahals, aiming to bring these forested areas under agricultural use. Alternative to Paharias: Having failed to subdue the Paharias, the British sought the Santhals as an alternative group. Suitable Settlers: Santhals were perceived as ideal settlers due to their proficiency in clearing forests and vigorous land cultivation, making them desirable to both the British and Zamindars. Damin-i-Koh Demarcation: By 1832, a significant tract of land was designated as Damin-i-koh, established as Santhal territory in the Raj Mahal foothills.
