The earlier geographers that told him that were Ptolemy and Paolo Toscanelli.
While the "Native Americans," the Norse, the Chinese and perhaps others discovered America earlier, the discovery by Columbus in 1492 is considered the "official" date of discovery becasue that is the discovery from which the modern world descends.
Very brief, however, the first people who arrived were (arguably) said to be the Dutch. However, the others who also arrived earlier on than the colonial era, likely made it with the use of ships or boats.
Native Americans like to be given the credit that they deserve, for having been in the Western Hemisphere earlier than any other ethnic group; they also do not appreciate the term Indian which is based upon the mistaken belief of Columbus that he had traveled to India, rather than to a hemisphere previous unknown to Spain.
We don't know the grievances you ask about.
No, obviously not.
How about Columbus, Ohio - Christopher Columbus.
Umm... he didn't, he was born in 1254, MUCH earlier than Columbus.
490 years earlier.
he made it to America
he was the first explorer to have a written record of his journey
"Pre-" I believe :)
they are differ by explorers
It is later, I do believe. :]
He went west instead of sailing east.
His route was different because he sailed west to go east.
No. The Pilgrims, trying to reach Virginia, came to Massachusetts in 1620. Columbus discovered America in 1492. The Vikings discovered America some 500 years earlier than Columbus, but their settlements failed and their discovery was not evvectively followed up.
Columbus was looking for a route across the Atlantic Ocean to India and reached the Caribbean instead. His discovery was a mistake, and although Vikings had come to North America from Europe several hundred years earlier, Columbus is still credited by some with having discovered America.
