Leif Ericsson was the explorer who is believed to be the first European to arrive at the North American continent. He arrived in 1000 CE and established the first settlement called Vinland. He was son of Eric the Red, Eric is credited with the discovery of Greenland and building the first settlement there. His accounts had been passed down as legends through the vikings sagas.
