Prior to the arrival of europeans to the new land, a population existed in north america. what are appropriate terms for these original inhabitants? -native americans -indigenous people -vikings -natives -first people

I think that indigenous peoples would be the most common term to describe the natives who first populated the New World and they are considered to have walked across the Bering Sea when it was dry land when the sea level dropped during the last great glaciation. These peoples could also be called Native Americans (in the sense of being from all the Americas) natives and First People (or First Nations).

It is the doctrine that the us had the right and duty to expand throughout north america. it just means they believed they had the right to expand westward and they did! they stated with the 13 colonies and then they kept moving gaining different territories throughout the years
