The story begins in 1492 when Christopher Columbus reached the Caribbean, initiating contact between the Old World and the New. Spanish crown ambitions, missionary zeal, and the lure of gold propelled fleets to the Americas. Early voyages carried horses, wheat, and livestock to indigenous societies, while native staples such as maize, cassava, and potatoes embarked on the reverse route aboard the same ships, laying the groundwork for an unprecedented biological exchange.
The exchange accelerated in the 16th and 17th centuries as colonial economies demanded cash crops and the Atlantic slave trade expanded. Sugarcane plantations flourished, fueled by African labor, while silver from New World mines financed European wars. Simultaneously, diseases like smallpox devastated Indigenous communities, reshaping demographic patterns across the hemisphere. By the 18th century, a complex web of commodities, labor, and ideas connected continents, setting the stage for the modern global economy.
