On this day 574 years ago, March 9, 1451 (February 7, 1451 lunar calendar), the Italian explorer Amerigo was born. The full name of America is "America". How did it get its name? It has to be said that in the late 15th and early 16th centuries, Europeans opened up shipping routes to India and America, thus discovering the New World of America. The original inhabitants of the American continent were Indians. In the early 16th century, it was still very backward, some had just entered the feudal principalities, and some were stuck in the tribal society stage. At this time, in some Western European countries, capitalism had already sprouted. The emerging bourgeoisie was eager to plunder wealth from abroad, especially to search for gold, so there were expeditions to open up new shipping routes. Columbus, an Italian Genoese, made four voyages to the Americas from 1492 to 1504 with the support of the king of Spain. He successively discovered islands and lands such as Jamaica, Puerto Rico, and Dominica, and saw Honduras and Panama in Central America, and even reached the mouth of the Olinoco River on this side of the South American continent. Columbus's expedition results are customarily called "the Great Discovery of Geography" or "the Discovery of the New World" in world history. At about the same time as Columbus's expedition voyage, a man named Amerigo sailed three times to the northern part of South America that Columbus "discovered" in seven or eight years from 1497 to 1504. After field investigations, he proved that this land was not ancient Asia, but a "New World" or "Discovery of the New World". After his return to Europe, Amerigo drew up-to-date maps and published a widely read travelogue, "Stories of Sea Travel," which concluded that the place was not India, but the new "continent." Later generations named the new continent after him, thus giving the name Amerika in history and geography. Amerigo was born in Florence, Italy on March 9, 1451, and died in 1512. He was a famous navigator.
