The Story

5 Chapters · This narrative combines documented history with dramatized scenes for storytelling purposes.

Governance

Government Type
Empire (Triple Alliance with hegemonic monarchy)
Notable Dynasty
The Mexica royal house, founded by Acamapichtli and continued by his successors, including Itzcoatl, Moctezuma I, Ahuitzotl, and Moctezuma II.
Political System
The Aztec Empire was a confederation of three city-states—Tenochtitlan, Texcoco, and Tlacopan—known as the Triple Alliance. However, Tenochtitlan assumed a dominant, hegemonic role, especially after the mid-15th century. The political system centered on the figure of the tlatoani ("speaker" or king), who wielded supreme authority over military, religious, and administrative matters. The empire was not a unified state in the modern sense, but a tribute-based system where conquered city-states retained local rulers under the oversight of imperial officials and tribute collectors.
