There were several groups of people who came to America between Leif Eriksson and Columbus. The Vikings, led by Leif Eriksson, were the first Europeans to reach North America around the year 1000, but they did not establish any long-term settlements. After them, various other explorers and traders from Europe, Africa, and Asia made their way to America.

One notable group was the Norsemen, who established a short-lived settlement at L'Anse aux Meadows in modern-day Newfoundland, Canada around the year 1000. Other groups that may have visited North America include the Irish, Welsh, and Basque fishermen.

In addition, there were also various indigenous peoples who had already been living in the Americas for thousands of years before any European contact. These groups include the Native Americans in North America, and the various indigenous peoples of Central and South America.
