Concept:Damin-i Koh was a designated land area in the Rajmahal hills given to the Santhal tribe by the British.
Explanation:The term "Damin-i-Koh" is Persian meaning "skirts of the hills".
It was located in present-day Jharkhand (Sahebganj, Pakur, Godda districts).
By 1832, the British demarcated a large area and declared it as the land of the Santhals.
The Santhals were persuaded to settle there, practice plough agriculture, and become settled peasants.
Land grants required at least one-tenth of the area to be cleared and cultivated within the first ten years.
The area was enclosed with boundary pillars, separating it from settled agriculturists and the Paharias.
After demarcation, Santhal settlements expanded rapidly—from 40 villages in 1838 to 1,473 villages by 1851, and population from 3,000 to over 82,000.
Answer:Option A: A large area of land demarcated and declared to be the land of the Santhals.
