Read and complete the sentence. Americans get a day off work on October 10 to celebrate Columbus Day. It is an annual holiday that commemorates the day on October 12, 1492, when the Italian explorer Christopher Columbus officially set foot in the Americas, and claimed the land for Spain. It has been a national holiday in the United States since 1937. It is commonly said that "Columbus discovered America." It would be more accurate, perhaps, to say that he introduced the Americas to Western Europe during his four voyages to the region between 1492 and 1502. It's also safe to say that he paved the way for the massive influx of western Europeans that would ultimately form several new nations including the United States, Canada and Mexico. ___________ of the discovery of America were unveiling of the world map, conquest and colonization of the American continent by Europeans, submission of the Amerindian populations to the western military, political, religious and cultural order, commercial expansion of Europe, settlement of the hegemony of the conquering kingdoms: Spain, Portugal, England, France and the Netherlands, development of the transatlantic economy and others.
