Answer:
The Indian Removal Act maintained more continuity because it continued the policies of removal and genocide of the indigenous populations who lived in the Eastern United States.
Ever since the first european settlers arrived in the United States, Native Americans had been forced to live in the most remote areas. With the advancement of the white population, the tribes were relocated, first, to regions far from the eastern coast, and finally, to reservations west of the Mississippi River. This was precisely what the Indian Removal Act did.
