The year 1492 is historically significant for several reasons, most notably for Christopher Columbus's first voyage to the Americas. This event, sponsored by Spain, led to European awareness of the New World, initiating age of exploration and colonization that would have profound consequences for indigenous populations in the Americas as well as for Europe itself. This year also marks the completion of the Reconquista, with the expulsion of Moors from Spain. Thus, 1492 represents a critical turning point that catalyzed an extensive exchange of goods, culture, and ideas known as the Columbian Exchange.
