How did the interactions between native Americans and European immigrants shape the united States?

N the fifteenth century, when European settlers began to arrive in North America, the continent was richly populated with Native American communities. Hundreds of thousands of people lived in a wide range of environments from shore to shore, each community or nation with its own distinct culture. The centuries that followed the arrival of Europeans were years of tremendous upheaval, as the expansion of settler territory and the founding and growth of the United States resulted in Native American communities being moved, renamed, combined, dispersed, and, in some cases, destroyed.
