Leif Erikson is the name of the Viking explorer credited with reaching North America around the year 1000. He is believed to have landed on the northeastern coast of what is now Canada, specifically in a place he called Vinland. This exploration predates Christopher Columbus's voyages by nearly 500 years and is often noted as one of the earliest known European contacts with North America. Erikson's journey and the Norse settlements highlight the maritime prowess and exploratory spirit of the Vikings during the late 10th century, showcasing their influence beyond Europe.
