please give me a introduction overview of the federal government's policy towards the natives post civil war

They kicked out more natives from their land.

Explanation:

After the civil war, the US expanded its territory to great lengths. Though it was not the epitome of the manifest destiny period, America had very expansive motives. This led to many Natives getting kicked from their own land in states that hadn't yet been settled. Post civil war federal policies towards native Americans included: the removal to reservations to land allotment, Indian policy after the Civil War was characterized by intense battles over tribal sovereignty, the assimilation goals, citizenship, landholding and land use, and state development.

The civil war was a time where the US tried to unify again, but they left the natives out of that equation.
