Yes, Christopher Columbus went to his grave believing he had reached the outer edge of Asia, referring to the Caribbean and Central American lands he found as the "Indies".The Historical Realit yThe Miscalculation: Columbus severely underestimated the Earth's size. He mixed up different historical miles and measurement units, which made the globe seem much smaller on paper.The Refusal: Despite leading four separate voyages to the Americas between 1492 and 1504, he refused to accept that he had encountered an entirely unknown new continent.Until the End: Until his death on May 20, 1506, in Valladolid, Spain, he insisted that the islands he visited were part of Asia.
