Montezuma sacrifices slaves to build Aztec cities in Civilization VI

Now that I've covered all the civilizations which are new to the Civ franchise in the Gathering Storm expansion, I'm going to cover the other civs that my Patrons voted on. I'm going to start with Montezuma of the Aztecs. The Aztecs were included as DLC for the vanilla release of Civilization VI.

The Aztec Empire consisted of a "Triple Alliance" between the city states of Tenochtitlan, Texcoco, and Tlacopan in the Central Mexican Valley basin around Lake Texcoco, based largely around the cultivation of maize. They would subjugate other city states through military conquest, trade, or marriage, and then install governors to administer those client states without necessarily needing to maintain a military garrison. Client states would pay tribute directly to the Aztec emperor, who would limit their ability to communicate and trade directly with other client cities; thus, making each of the clients dependent on the empire for resources and luxury goods and reduce the likelihood of an uprising.

In the early 1500's, Spanish Conquistadors (lead by Hernán Cortéz) arrived in central Mexico and occupied the Aztec capital of Tenochtitlan, keeping Aztec Emperor Moctezuma Xocoyotzin a prisoner in his own palace. Since most of his history is depicted through the lens of the Spanish conquerors, information about Moctezuma's life and rule are limited and contradictory. He ruled the Aztec Empire at its territorial height after several successful military campaigns, and he imposed regressive policies that increased the rigidity of the Aztec caste system and severely limited the ability of commoners to work in royal palaces or ascend to nobility. Contrary to his typical depictions in the Civilization games as a blood-thirsty warmonger, contemporary Spanish writings suggest that Moctezuma may have been rather meek and was accommodating of the Spanish conquistadors, whom he invited to live in the palace as guests. Moctezuma would die during the Spanish occupation of Tenochtitlan, possibly having been stoned to death by his own citizens who were frustrated with his inability (or unwillingness) to repel the Spanish invaders.

DISCLAIMER:
Civilization VI is still a "living game". Strategies for the game (and for specific leaders and civs) may change as Firaxis applies balance patches, introduces new features, or expands the game through further DLC or expansion packs, or as the Civ community discovers new strategies or exploits. As such, the following strategy guide may change from time to time. I will try to keep it up-to-date, and will make notations whenever changes are made. I'll also post links in the official 2K forums and CivFanatics, where I'll also report any changes made. If possible and practical, I will try to retain the original content of the strategy for posterity.

I welcome any feedback or suggestions that readers wish to offer. Feel free to post on the linked forums, or by posting a comment at the bottom of the page.

This guide is up to date as of the release of the Gathering Storm expansion's "Red Death" update (ver. 1.0.0.341)

The Aztecs in Civilization VI are built to be highly aggressive, using the procurement of luxury resources to strengthen their armies and support their vast conquests.
