How did the Inca Empire compare with the Aztec?

The Inca Empire, located in the Andes of South America, was known for its extensive road systems and agricultural innovations, including terrace farming. In contrast, the Aztec Empire, centered in present-day Mexico, was characterized by its complex social structure and urban centers like Tenochtitlan. While the Inca were more focused on administrative efficiency and integration of diverse cultures, the Aztecs emphasized military conquest and tribute systems. Both empires were highly organized and influential, but their approaches to governance, economy, and society differed significantly.
