Leif Ericson (Old Norse: Leifr Eiríksson; modern Icelandic: Leifur Eiríksson; modern Norwegian: Leiv Eiriksson) was an Icelandic-Norwegian explorer and the first European to discover North America—more specifically, the region that would become Newfoundland and, by later extension, Canada.
It is believed that Leif was born around 980 and was the second son of Eric the Red (Old Norse: Eiríkr rauði), a Norwegian-Icelandic outlaw, himself the son of another Norwegian outlaw, Þorvaldr Ásvaldsson. Leif's mother was Þjóðhildr. Eric had started two Norse colonies, the Western Settlement and the Eastern Settlement, in Greenland, which he had named. As far as it is known, Leif Ericson had two brothers, Þorvaldr and Þorsteinn, and one sister, Freydís. Leif married a woman by the name of Þórgunnr and they had one son, Þorkell Leifsson.
During a stay in Norway, Leif was converted to Christianity, like many Norse around that time. He also went to Norway to serve King Olaf Tryggvason. When he returned to Greenland, he bought the boat of Bjarni Herjólfsson and set out to explore the land that Bjarni had found which today we know as North America.
The Saga of the Greenlanders tells that Leif set out about 1000 to follow Bjarni's route in the opposite direction.[1] The first land he met was covered with flat rock slabs (Old Norse: hellur). He therefore called it Helluland ("Land of the Flat Stones"), which is probably the present day Baffin Island. Next he came to a land that was flat and wooded, with white sandy beaches, which he called Markland ("Wood-land"), which is assumed to have been Labrador.
When Leif and his men found land again after leaving Markland, they landed and built some houses. They found the land pleasant: there were plenty of salmon in the river and the climate was mild, with little frost in the winter and green grass year-round. They remained at the place over the winter. The sagas mention that one of Leif's men, Tyrkir, a German warrior, found grapes, and Leif named the country Vínland after it.
On the return voyage, Leif rescued an Icelandic castaway named Þórir and his crew, an incident that earned Leif the nickname 'Leif the Lucky' (Old Norse: Leifr hinn heppni).
Research done in the 1950s and 60s by explorer Helge Ingstad and his wife and archaeologist Anne Stine suggests that the settlement of Leif Ericson and his party in Vínland was actually the tip of Newfoundland later known as L'Anse aux Meadows.
In 1964, President Lyndon Johnson declared 9 October Leif Erikson Day in the United States.
