The United States was not always divided into the 50 states we know today. Many distinct Indian tribes originally inhabited each of the regions that are now part of the country.
Currently, it is thought that the continent’s original inhabitants arrived between 10,000 and 20,000 years ago, after crossing a “land bridge” between Asia and North America.
