Many people know Christopher Columbus.
Columbus landed on the coast of America in 1492.
Many people think Christopher Columbus was the first person to discover North America.
However, that is not true!
Five hundred years before Christopher Columbus, another explorer landed in North America.
Leif Erikson was a Viking explorer.
When he landed in North America, he called the new land 'Vinland' after the vines he saw growing there.
