When i saw the topic i thought i remembered something about viking settlements on North America, and i was able to find this qoute via google :
"In 986 Bjarni Herljufson discovers Vinland, which will be explored by Leif Eriksson. The expeditions multiply. Vikings establish villages. Nobody deny anymore, today, that viking's " vine land" was North America.
What is less known, and less admited, is that vikings also landed at South America. This is demonstrated by linguistic and toponymic ascertainments. Conquistadors even found a white indians tribe."
