When you hear the phrase 10 steps rise, you might picture a modern business plan, but the Aztecs followed a ten‑stage saga that turned a wandering tribe into a world‑shaking empire. Below we walk through each dramatic chapter, from celestial myths to the blood‑stained battlegrounds, preserving every vivid detail that made the Mexica unstoppable.

10 The Five Suns

The Aztec pantheon wove together countless neighboring cultures, and their creation story – the Legend of the Five Suns – survived in many variations yet kept a core narrative. In this myth, the deities attempted to fashion the human world five times, each era ruled by a different sun god. The first four suns met violent ends, while the fifth endured, giving rise to the world we know today.

One popular version tells of the gods gathering in absolute darkness to summon the fifth sun. The spark required a divine sacrifice: a god plunging into a blazing fire. Two candidates stepped forward – the vigorous Tecuciztecatl and the frail, elderly Nanahuatzin. The younger god was initially chosen, but when Tecuciztecatl approached the flames, fear seized him. Nanahuatzin, despite his age, leapt without hesitation, becoming the radiant Sun. Ashamed, Tecuciztecatl followed, but his sacrifice birthed the lesser moon.

The lesson was clear: the gods’ own self‑sacrifice birthed humanity, and the Aztecs never forgot the debt owed to those celestial benefactors.

9 The Aztlan Exodus

The Nahua peoples, a collection of tribes sharing a common tongue, originally roamed Central America. Legend says they emerged from a realm of seven caves, establishing a homeland called Aztlan. Some accounts paint Aztlan as a utopia; others, especially the Mexica, remembered it as a place of oppression under harsh masters.

Guided by the warrior‑god Huitzilopochtli, the Mexica broke free and trekked southward. Shedding their tribal label – which meant “people from Aztlan” – they adopted the name Mexica. Later historians would once again call them “Aztecs.” By the time they arrived, rival Nahua groups had already claimed the fertile valleys and formed warring city‑states. The Mexica negotiated with the local ruler of Culhuacan, securing a modest plot of land that was far from prime farmland. To survive, they entered the Culhuacan army as mercenaries, earning their keep through warfare.

8 The Flayed Princess

As the Mexica assimilated the culture of their patron city‑state, they grew more refined, religious, and technologically adept. Their martial prowess impressed the king of Culhuacan, who eventually agreed to a marriage alliance: the king’s daughter would become the Mexica queen and, symbolically, the consort of Huitzilopochtli – the deity who was already dead and deified.

During a banquet held in the princess’s honor, the king was horrified to discover a ceremonial dancer garbed in the princess’s own skin. The Mexica had performed a sacrificial marriage, offering the princess’s flesh to the gods. Incensed, the king declared war. The Mexica, bewildered by the perceived betrayal, were driven out and forced to settle on the marshy island of Texcoco. There, on a lone islet, they witnessed an eagle perched on a nopal cactus – a divine omen that affirmed their destiny to build a city there.

7 The Artificial Island

The Mexica’s first task on the islet was to transform it into a livable island. They dug drainage canals to reclaim marshland, yet the limited space demanded more ingenuity. Their solution: the creation of floating gardens known as chinampas.

They marked out rectangular plots, each as long as a skinny football field, within shallow riverbeds. Using wattle—a blend of clay, reeds, and animal dung—they built sturdy walls around each plot. Workers then piled sediment, mud, and decaying vegetation inside the enclosures until the surface rose to water level.

Next, a lattice of floating sticks was woven, over which reeds and river‑bottom mud were layered, forming fertile soil. These chinampas produced up to seven harvests a year, far outpacing traditional agriculture and sustaining the burgeoning city.

6 Tezozomoc’s Stone Fist

The fledgling Mexica could not fend off all hostile city‑states on their own, so they entered a tributary relationship with Tezozomoc, the formidable king of the Tepanec Empire, also serving as mercenaries in his army.

Tezozomoc was a demanding ruler, exacting heavy taxes. One clever Mexica leader reduced this burden by marrying one of Tezozomoc’s many daughters. The strategy succeeded; the king grew fond of the Mexica and later wed additional daughters to other Mexica nobles.

Tezozomoc became a stern step‑father figure, granting the Mexica the state of Texcoco as tribute. Under his protection, the Mexica ruler finally earned recognition as a king among the Nahua tribes. Meanwhile, the island of Tenochtitlan expanded: marshland filled with soil, reed huts gave way to stone houses, aqueducts were erected, and more chinampas and canals turned the settlement into a New World Venice. Grander temples rose, evolving into the iconic step‑pyramids we associate with the Aztecs today.

5 Maxtla The Usurper

When the Mexica king died, Tezozomoc appointed his favored grandson, Chimalpopoca, as successor. Because Chimalpopoca was still a boy, Tezozomoc acted as regent until the heir came of age. Yet even after reaching maturity, Tezozomoc deemed Chimalpopoca incompetent and continued to rule as regent for another six decades.

Tezozomoc lived past a century before his death. His eldest son Maxtla believed he was the rightful heir to the Tepanec throne, but the council chose his brother instead. In retaliation, Maxtla murdered his brother and anyone who opposed his claim. Chimalpopoca sided with the slain brother, and soon after Maxtla seized power, Chimalpopoca was assassinated, plunging the region into further turmoil.

4 The Battle Against Maxtla

The Mexica could not avenge Maxtla alone; they needed allies. Prince Nezahualcoyotl, nephew of the Texcoco king, had been exiled after the Tepanecs murdered his uncle. When Maxtla’s treachery erupted, Nezahualcoyotl returned to reclaim his throne.

Seeing a shared desire for vengeance, the Mexica allied with Nezahualcoyotl, and together they persuaded a third nation to join their cause. This coalition became the famed Triple Alliance, the foundation of the Aztec Empire.

Unlike typical Nahua warfare, which aimed to maim for captives, the Triple Alliance attacked the Tepanec capital without taking prisoners. The streets ran with bodies; Maxtla fled to his palace and was reportedly discovered in the steam baths, where Nezahualcoyotl slew him with his own hands. The Tepanec capital was razed, and the Triple Alliance, led by the Mexica, expanded its dominion.

3 The Puppet Master

Tlacaelel served as a guiding hand to several Aztec monarchs, engineering the Triple Alliance to avenge his brother Chimalpopoca and to support his other brother, Moctezuma, the future emperor.

He crafted laws that unified the empire, but his methods were ruthless. When a conquered nation threatened stability, Tlacaelel would eliminate or exile its ruler, installing a compliant puppet. He even ordered the burning of both foreign and indigenous books, rewriting history to erase the Mexica’s nomadic origins and recasting them as a chosen people. He elevated Huitzilopochtli from tribal hero to supreme sun god, whose survival depended on continual human sacrifice.

In peacetime, Tlacaelel introduced the “Flower Wars,” pre‑arranged conflicts designed solely to capture prisoners for sacrificial rites, ensuring a steady flow of offerings to the gods.

2 Jaguar And Eagle Knights

Aztec society was a strict hierarchy: royalty, priests, nobles, commoners, and slaves. To keep the lower classes from rebelling, the elite offered a path to prestige – becoming an Eagle or Jaguar Warrior, akin to European knighthood.

Advancement required capturing enemies in battle and delivering them to temples for sacrifice. A warrior who secured twenty captives earned the title, granting him noble status, palace meals, alcohol, and even concubines. In practice, most knights were already nobles; commoners who rose were rare exceptions.

The Jaguar warriors donned the skins of spotted cats, while Eagle knights sported feathered regalia. Their weapons included obsidian‑tipped clubs, slings, spears, and daggers. Battles were rarely about killing; the primary goal was to procure fresh victims for the sacrificial altar.

1 Human Sacrifices

The Aztecs believed they lived within a 52‑year cosmic cycle, during which the Sun perpetually battled the Moon and stars. If the Sun did not receive enough nourishment—human offerings—it would fail to rise, casting the world into darkness. They thought human hearts were fragments of the Sun; priests would slice open a victim’s chest, lift the still‑beating heart to the sky, and return the fragment to its celestial source.

Sacrifices were not limited to the Sun. To appease the rain god Tlaloc, they offered children, urging them to weep, for tears promised abundant rain and bountiful crops.

Occasionally, priests would invite a deity’s spirit to inhabit a mortal, treating that person as the living embodiment of the god, honoring them with offerings until the appointed year, when the deity‑possessed individual was sacrificed. The gods themselves were believed to have sacrificed for humanity, creating a reciprocal cycle of blood and devotion.

More Sacrifices

When young Aztec warriors returned with captives, the prisoners faced ritual combat. They were chained and handicapped while four Jaguar Knights engaged them one‑by‑one. If a captive survived the individual assaults, the knights attacked en masse. Should the captive still endure, a priest would perform a traditional sacrifice.

One notable captive, after fighting alongside the Aztecs, was offered freedom and a journey home. He declined, insisting on being sacrificed, viewing the act as an honor to serve the community.

At the close of each 52‑year cycle, the Aztecs extinguished all flames at night. If the Sun rose the next morning, it signaled that the previous sacrifices had sufficiently nourished the gods. A final man would be sacrificed, his chest opened, a flame lit within his body, and that fire used to rekindle all village lights—much like the modern Olympic torch ceremony.
