It was in the year 1832 that the British demarcated a large area of land as Damin-i-Koh for settling the Santhals. Damin-i Koh is in the area of Sahebganj, Pakur, and Godda districts in the Jharkhand. British persuaded the local tribe of Rajmahal Hills i.e. Santhals to live in the foothills of Rajmahal by giving land to them. "Damin-i-Koh" is a Persian term that means 'skirts of the hills'.
