Using present-day locations in this description, the Maya civilization incorporated most of the southern third of Mexico, including both coasts and extending southward into Guatemala, but not eastward to the Yucatan Peninsula. The Aztec empire incorporated all of the Yucatan Peninsula, extending southward into Guatemala, Belize, and northern Honduras. The Inca empire in 1400 A.D. was relatively small, incorporating the Andes mountain region from southern Peru to northern Boliva. In 1532, the empire had expanded to incorporate all of Ecuador and Peru, northern Chile, western Bolivia, and western Argentina. The Inca map also shows the Inca Road, which extended throughout the empire.
