• 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 territory was surveyed and mapped.
• Enclosed with boundary pillars, it was separated from both the world of the settled agriculturists of the plains and the Paharias of the hills.
• After the demarcation of Damin-i-Koh, Santhal settlements expanded rapidly.
