The introduction of new crops refers to the transfer and cultivation of plants and agricultural practices between the Old World and the New World, significantly impacting diets, economies, and cultures on both sides of the Atlantic. This exchange included staple crops like potatoes, maize, and tomatoes from the Americas, which were integrated into European agriculture, while Europe introduced crops such as wheat and sugarcane to the Americas. These new agricultural practices contributed to population growth and changes in societal structures.
