Explanation:

Pathagarhi Rebellion

• It is a protest in which tribal people embed stone slabs (pathals) on the outskirts of a village or area, demarcating the limits of where their writ runs, prohibiting the entry of any institution connected to the state.
• The state government of Jharkhand tried to amend the Chotanagpur Tenancy Act, 1908 and Santhal Parganas Tenancy Act, 1876 to facilitate easier land acquisition norms which added to the problem. They were also withdrawn later on.
