The Atlantic World marked the beginning of globalization, connecting Europe, Africa, and the Americas through trade, colonization, and cultural exchange. This era saw the Columbian Exchange, which transformed ecosystems and diets worldwide, and the rise of mercantilism as a dominant economic theory. European exploration led to the conquest of indigenous civilizations and the establishment of colonies in the Americas. The transatlantic slave trade forcibly moved millions of Africans, reshaping demographics and economies. These interactions resulted in cultural hybridization and long-lasting social, economic, and environmental impacts.
