The Columbian Exchange refers to the widespread transfer of plants, animals, goods, and ideas between the Old World (Europe, Africa, and Asia) and the New World (North and South America) following Christopher Columbus' arrival in the Americas in 1492. It initiated a period of significant cultural, ecological, and economic exchanges that lasted from around the late 15th century to the early 17th century. So, the time period for the Columbian Exchange spans roughly from the late 1400s to the early 1600s.
