The first settlers in America were paleo-indian peoples.  Their origin is not known.  Some claim they migrated from Asia, but that makes little sense because American Indians are very different in many ways from Chinese and Asian Indians.  Even their blood types are typically different.

Some old mounds reflecting Indian settlements in America have been discovered, such as the Adena burial mounds and Mississippian platform towns.<ref>Melissa L. Meyer, Dean R. Snow, Charles L.

The American Indians, also called Native Americans, were [[nomads]] who traveled across wide areas.  They did not read and write, and they lacked a monetary system.  They were organized by tribes and some had simple forms of government.  There was the [[Iroquois Confederacy]] that united some, but typically there was a lack of unity that led to their easy defeat by Europeans.  The Indians did introduce [[tobacco]] and [[corn]] to Europeans, and they became widely popular back in Europe.
