Answer :

The Aztecs controlled the most powerful empire in Mexico.

Explanation:
1. The Aztecs were a Mesoamerican civilization that flourished in central Mexico from the 14th to the 16th century.
2. Their capital city, Tenochtitlan, was located in present-day Mexico City.
3. The Aztec Empire was known for its military strength, advanced agricultural practices, intricate social structure, and impressive architectural achievements.
4. Through conquest and alliances, the Aztecs established a vast empire that included a large part of central Mexico.
5. Their control over resources, trade routes, and tribute from conquered regions made them one of the most powerful empires in the region at that time.
6. Therefore, the Aztecs controlled the most powerful empire in Mexico, not in Peru, Bolivia, or Panama.
