The U.S. government sets aside lands as reservations for Native Americans.
Option C
<u>Explanation:</u>
The idea of an Indian territory seems to be a predecessor to the British Indian Reservation, which was developed by the Royal Declaration of 1763, and which set aside land for the indigenous people.
The proclamation confined the European population to Crown estates east of the Appalachian Mountains. Towards the conclusion of the US war in Paris (1783), the region remained active, and land was ceded to the US. In the aftermath of the U.S. Rebellion, the British Government limited the Indian Reserves' area of land until the only lands west of the Mississippi river were included.
Most Native American tribes had established ties with the British who have been faithful to the British Empire during the American revolt, but had less established connections with the colonist insurgents of the Commonwealth.
