Pre-Columbian era
is not definitively known how or when the Native Americans first settled the Americas and the present-day United States. The prevailing theory proposes that people migrated from Eurasia across Beringia, a land bridge that connected Siberia to present-day Alaska, and then spread southward throughout the Americas. This migration might have begun as early as 30,000 years ago[1] and continued through to about 10,000 years ago, when the land bridge became submerged by the rising sea level caused by the ending of the last glacial period.[2] These early inhabitants, called Paleoamericans, soon diversified into many hundreds of culturally distinct nations and tribes.
