Additional Notes:

Architecture: Legend tells us that the first building constructed in Tenochtitlan was the temple honoring the Aztec god(H)Uitzilopochtli. We know that the Valley of Mexico was heavily populated at this time, and many of the surrounding towns had public buildings. Many of these buildings were temples. We also know that Tenochtitlan was well planned, and its aqueducts, roads, canals, and buildings were constructed by highly skilled masons. The Aztecs used limestone rocks and adobe bricks in their construction. Houses all had inner courtyards, they were painted white, and had flat thatched roofs. Only the nobility were allowed to have two stories.

Naval units: Early Spanish writers commented on the fact that the lakes all round the Aztec capital were peppered with canoes of all shapes and sizes: carrying goods to and from the city (and especially the great market at Tlatelolco), removing waste, ferrying warriors and raiding parties and - as in Venice - doing many of the every-day transport jobs now carried out in cities by buses and lorries. River/lake/canal transport is a very efficient means of getting goods from A to B. In a society without wheeled vehicles or draft animals, the canoe played a crucial role in moving heavy loads. Indeed, the growth of Tenochtitlan and Tlatelolco into one of the world’s largest cities was certainly due in part to the huge success of the fast-moving, largely water-bound, traffic to and from the main market. Most general purpose canoes averaged 14 feet in length, were dug out from a single tree trunk and with upturned ends, and were propelled by wooden pole (or paddle). At the other extreme, the largest canoes, made of straight-grained spruce trees, were 50 or more feet in length, capable of carrying either 60 passengers or 3 tons of maize. Little wonder that the Náhuatl word for canoe was acalli or ‘water-house’, from the two words atl (water) and calli or house: the Spanish noted that Aztec boatmen would often sleep in their travelling canoes on long journeys

Language progression:

The Aztecs would speak the Nahuatl Language, although it hard to point out exactly how the langauge developed. There is a recorded difference between what was termed Paleonahua and Neonahua. The Paleonahua developed over several centuries, beginning its process of change during the Teotihuacan era, being more conservative in eastern Mesoamerica. Neonahua, however, arose when the Toltec-Chichimecs spread throughout much of the Valley of Mexico, with linguistic innovations such as the addition of the sound /tɬ/.

Landmark references:

  • Cuicalli:

    Translated into House of Song, it was the place where boys and girls gathered to relax in the evening, meet and make friends and have fun. Becoming an important center for cultural learning.

  • Toltec Warriors of Tula:

    Also known as the Atlantean Figures, are four anthropomorphic statues belonging to the Toltec Culture. Built on top of the Pyramid known as Tlahuizcalpantecuhtli as they are said to represent warriors, possibly soldiers following the god-king Quetzalcoatl. Quetzalcoatl, also called the Feathered Serpent, is associated with Venus; as the story goes when he died here on earth he went up to the sky and became the Morning Star. The name of the pyramid – Tlahuizcalpantecuhtli – means “The Temple of the Morning Star.”
    The Aztecs revered the Toltec culture as part of their ancestral heritage and also built their own version of statues within their capital of Tenochtitlan.

  • Tlachtli:

    Was the field the Aztecs played their game called Ollama. It was played by the Aztec forebears, the Mayans, but in Aztec society, the game received an elevated status and was played only by the nobles. As with many other things in Aztec society, the game could get extremely violent. Instead of a halftime show, human sacrifices were involved in the Ollama ritual. Additionally, they were allowed to try to rob the spectators whenever one team scored. The other way in which the audience participated in Ollama was through betting, which they apparently did quite heavily. In fact, two of the great evils Aztec children were warned about were excessive ball playing and gambling. Nonetheless, there are reports of Aztec citizens betting so heavily on the game that they were forced to sell themselves into slavery to pay their debts.

  • Acatitlan Teōcalli:
    The Temple used to be a part of a political and religious center of the time, later annexed by the Mexica and became part of the lacustrine culture under the rule of Tenochtitlan.**

  • Palace of Nezahualcóyotl :

    The palace also served as a government meeting center, and contained administrative rooms such as courtrooms for nobles and commoners, council chambers for accomplished warriors, rooms for storing tribute, armories filled with weapons, rooms that housed all manner of servants and caretakers, and also quarters decked out to house visiting rulers. Indeed, the palace was meant to impress and intimidate royal visitors, whether friendly allies or fierce enemies. But it was also a pleasant place, with gardens, ponds, an aviary, and a zoo. Such a center required the presence of a huge number of people: Hernán Cortés tells us that more than 600 nobles appeared in this palace daily, and their servants overflowed two or three of the palace’s large courtyards.

  • The Spiral Pyramid:

    is a part of the of Xochitécatl temple complex, which was the center of the Tlaxcalan Nation. Xochitécatl means “Place of the Flower Lineage”. The Tlaxcalan was the first Aztec or more precisely, Nuahatl nation to ally with the Spanish, and due to their loyalty, high-status Tlaxcalan would be given Spanish weapons and trained in using horses.
    The Spiral Pyramid was built around 700BC and is unlike any other Temples of the region, having no Staircases and being built in a conical shape resembling Popocatépetl, and is considered a representation of the volcano. However the Aztecs dedicated these spiral pyramids to the God of Wind, Ehécatl, one of the creator gods, sometimes interpreted as a form of Quetzacoatl. Since the wind blows from every direction, they associated Ehécatl with all the cardinal directions. They built his temple as a circular pyramid to reduce the air resistance, so he could fly around it without obstacles.
    The Spanish placed a cross on top of the Temple in 1632 after the conquest of the Aztec Empire.


  • Huēyi Teōcalli:

    Also known as Templo Mayor, The Temple was dedicated simultaneously to Huitzilopochtli, god of war, and Tlaloc, God of Rain and Agriculture. Each of which had a shrine at the top of the pyramid with seperate staircases, and served the main temple of the capital Tenochtitlan.

Aztec history has a lot of surprices, and is quite often a misunderstood history.
People have a tendency to sum up that the Aztec was 1 sole entity, but it was far from it.
And it was the very reason why the empire fall as fast as it did, it wasn’t only due to the Spaniards being technologically Overpowered. But because the Aztecs had managed to create a lot of emnity among their neighbours. And the Spaniards were merely the catalyst needed to overthrow the otherwise militarily superior Aztecs, or to be more exact, the Mexica-empire. Yes the name Mexico derives from what the Aztec called themselves: Mexica. As Aztecs was a term coined by the Europeans.
So all that was needed by the spaniards was to rally all the Nations which have been wronged by the Aztec empire to rise up against them.

Now with the 2 new civs of Ottomans and Malians having been announced by MS/Relic. They really showed how far one can push the boundries of the game.
New mechanics are getting added and even a full custom unit rooster (for the Malians).

This is something I’ve always had in mind for the Native-American civilizations. And now this brings bigger hope that these civ’s actually can be added to the game, as developters are willing to push the boundries.

The Malians were never a gunpowder civilization, infact, much like the Native-Americans, despite all their wealth, they never managed to obtain Gunpowder weaponry, despite them constantly seeking it out.

So for the gameplay on the Aztecs I wanted to focus on the Aztec warrior culture, Eagle warriors weren’t just men who ran really fast represented by AoE II and III.
But they were warriors equal if not a higher status of the more famous Jaguar warrior.
Infact the weaponry were the same between Jaguar and Eagles, and the only difference was the God that they represented and quite often their social status, Eagle warrior stemming mostly from nobiltiy while Jaguars were commoners.
In Aztec culture, Everyone (Except for females) Were trained to be a warrior.
And the way to become a Eagle or Jaguar warrior was to have gone out in battle and bring back 4 captives. Only then was one worthy to be a Eagle or Jaguar warrior.

The Jaguar and Eagle warriors are essentially boosted up regular units but with unique abilities ontop of it all.
The Eagle Warrior gets its signature mobility bonus, but also a charge attack.

While the Jaguar becomes someone who specialised in setting up ambushes and thrives in prolonged fights.
The Eagle and Jaguar warriors also believed that by donning the Eagle or Jaguar looks, they would inherit the fighting prowess sof the animal they represented.

Religion also played a very important aspect which is where their Unique Religious unit, Tlamacazui and their Unique Monestaries; Teōcalli, comes into play, converting units into Jaguar or Eagle warriors.
They also get access to their own Unique Horseman, the Tlaxcalan Cauallero.

The Tlaxcalan were of Aztec culture, but a victim of the Aztec flower war, they were being farmed by the Aztec triple alliance (what we recognize the as the Aztec Empire), for sacrefice. So when the Spaniards arrived, they were among the first to ally up with the spaniards despite having fought against them at their arrival.

They became quite loyal to the spanish, as well they played a key part in the spanish conquest of the Aztec Empire, that the Spaniards saw them as a higher class Natives in the americas, and gave them unique privileges in the spanish empire as well as training them in the use of Horses and providing them steel weaponry and armor, which quickly became a status symbol among hte Tlaxcalans.

Next up: Mayans or Incas. IDK. You choose.

Are here any history enthusiasts and have knowledge about Aztec warfare?

From my knowledge, Aztecs did not have navy or warships…

How about sieges? How they deal with walls and fortifications?

Perhaps adding a regional upgrade (since we would probably have a lot of native civs like this) called “European Mercenaries” or “European Technology” enabling the natives to use gunpowder or European siege units, this is probably more of a “band aid” solution rather than a proper one though.

They can have the same units of their counterparts of AoE 3…

I consider cavalry (coyote runner) or siege weapons (arrow knight) in “infantry form” - AoE3 concept as bad idea, and too unrealistic even for game

I would go with different type of melee/missile infantry + warrior priests

I would take note from TW Medieval 2: American campaign

Have played Aztecs in “Empire Apart” (age of empires clone)? If Yes, what do You think?

I think the ability to capture and sacrifice enemy units could work in AoE4


never heard of this before. But looks very interesting, i like their take on the civs.

1 Like

“Empire Apart” is Age of Empires clone with horrible graphics, and works with exactly with same AoE formula. You can try it for free on steam :

In my opinion - It is not better than AoE, but I admit, it has good and interesting ideas - In contrast with 0AD without good ideas:D

Yeah…can work anyway…the same the Mongols of AoE 4 actually works similar to their counterparts of Empires Apart (the mobile building system for example)…
