By 1832 the Santhals had settled in Damin-i-Koh area. Their settlement expanded rapidly. Forests were cleared to accommodate them. The Company also benefited as it got more and more land revenue. However, the Santhals too got dissatisfied They rebelled against the British rule. Following are the main causes for their rebellion.
1 Santhals were not happy with the tax regime of the company. They thought that the land revenue rates were high and exploitative
2 The Zamindars began to exercise greater control on the areas brought under cultivation by Santhals, apparently it was a part of the British Policy. But Santhals resented that.
3.Moneylenders in the rural areas were seen as villain and agent of Company rule by the Santhals. Moneylenders could auction the land of Santhals in case of defaulter. All this was not liked by the Santhals. The British took steps to placate the Santhals later on. A separate district of Santhal Pargana was carved out and law was enacted to protect the santhals.
