Answer: Indies
Explanation: Columbus believed he had arrived in Asia, whose medieval name was Indies. Believing that further travel would take him to China and Japan, he actually arrived on the coast of Cuba in 1492, which would be the year when America was actually discovered. Although there was plenty of evidence to suggest that it was not Asia, Columbus refused to admit that it was a completely new continent. Amerigo Vespucci, with his expedition, proved that this was what he called "New World", actually new continent across the Atlantic giving many evidence for this claim.
