The Santhals had begun to come into Bengal around the 1780s. Zamindars hired them to reclaim land and expand cultivation, and British officials invited them to settle in the Jangal Mahals. Having failed to subdue the Paharias and transform them into settled agriculturists, the British turned to the Santhals.The Santhals were given land and persuaded to settle in the foothills of Rajmahal. By 1832 a large area of land was demarcated as Damin-i-Koh. This was declared to be the land of the Santhals. They were to live within it, practise plough agriculture, and become settled peasants. The land grant to the Santhals stipulated that at least one-tenth of the area was to be cleared and cultivated within the first ten years.The Santhals gave up their earlier life of mobility and settled down, cultivating a range of commercial crops for the market, and dealing with traders and moneylenders.
