Christopher Columbus’s voyages were pivotal in establishing sustained contact between Europe and the Americas, which paved the way for European exploration, conquest, and colonization on a vast scale. Although his original goal was to find a new trade route to Asia, his Atlantic crossings revealed the existence of the Americas to Europeans, encouraging subsequent expeditions by other explorers and nations.12

These voyages initiated a period of profound transformation known as the Columbian Exchange, which involved the movement of people, plants, animals, commodities, and diseases across the Atlantic. This contact facilitated the colonization and exploitation of the Americas and their peoples. For Indigenous populations, the arrival of Europeans brought devastating consequences, including epidemic diseases, warfare, displacement, and enslavement. Furthermore, the trade routes established in the wake of these voyages laid the foundation for the transatlantic slave trade, which deeply impacted the social and economic structures of the Americas, Africa, and Europe.134
