The significance of the discovery of the New World in 1492 cannot be overstated, as it marked the beginning of extensive European exploration and colonization in the Americas. Christopher Columbus's voyage, sponsored by Spain, opened the door to transatlantic exchanges that transformed global trade, culture, and demographics. This event initiated the Columbian Exchange, leading to the importation of crops, animals, and ideas between continents while simultaneously resulting in devastating consequences for Indigenous populations, including diseases and displacement. The discovery ultimately redefined ecological, economic, and political dynamics worldwide, paving the way for the emergence of modern nations and economies.
