Norse Mythology: Gods, Runes and the End of the World
Discover Norse mythology: the nine worlds and Yggdrasil, gods like Odin, Thor and Loki, the runes, and the inevitable Ragnarök.

Can you imagine a city built on a lake, with canals running through it like golden veins, pyramids that touch the sky and floating gardens that feed hundreds of thousands of people? This is no science-fiction fantasy, but the reality lived by the Aztecs, one of the most sophisticated and powerful civilizations that ever existed in the Americas.
The Aztec civilization, or Mexica as they called themselves, did not just conquer territories; it conquered the imagination of historians, archaeologists and adventurers for centuries. Their history is an epic of transformation: from persecuted nomads to absolute lords of an empire that stretched from the Atlantic Ocean to the Pacific.
To better understand the magnificence of this civilization, we invite you to explore our full video on the Aztecs, where we unravel every aspect of their fascinating culture.

The history of the Aztecs begins wrapped in mystery and legend. According to their own chronicles, the Mexica came from a mythical place called Aztlán, “the place of the herons”, located somewhere in northern Mexico. But what truly marks the beginning of their greatness is a prophecy that would change the course of Mesoamerican history forever.
Their patron god, Huitzilopochtli, had promised them a divine sign: they would find their definitive home where they saw an eagle perched on a cactus devouring a snake. For decades, the Mexica tribes wandered the central highlands, rejected and persecuted by more established peoples who saw them as undesirable barbarians.
In 1325 AD, on a small rocky island in Lake Texcoco, the Mexica finally found their sign. There they founded Tenochtitlan, which literally means “place of the stone prickly pear”. What began as a humble settlement would become, in less than two centuries, the largest and most sophisticated city in the Americas.
The first years in Tenochtitlan were about survival and adaptation. The Mexica became tributaries of Azcapotzalco, the dominant power of the Valley of Mexico. However, this period of subordination taught them valuable lessons in politics, warfare and administration that they would later use to build their own empire.
The turning point came in 1428, when Itzcoatl, the fourth Mexica tlatoani (ruler), formed the Triple Alliance with Texcoco and Tlacopan to overthrow Azcapotzalco. This victory not only freed the Aztecs from the tributary yoke, but also marked the birth of the Aztec Empire proper.

Tenochtitlan was not simply a city; it was a masterpiece of urban engineering that amazed every visitor. Built on an artificial island in Lake Texcoco, the Aztec capital was connected to the mainland by three great causeways that also served as dikes to control the water level.
The city was organized into four great districts or calpulli, each oriented toward one of the cardinal points, with the ceremonial center as the pulsating heart of the metropolis. This center, dominated by the Templo Mayor, a stepped pyramid more than 60 meters tall, was the religious, political and economic core of the entire empire.
The canals that crossed the city were not just communication routes; they were vital arteries that allowed the transport of goods, people and, crucially, fresh water from the springs of Chapultepec. A complex system of locks and gates regulated the flow of water, demonstrating hydraulic knowledge that had no equal in the Americas.
One of the most brilliant innovations of the Aztecs was the chinampas, artificial gardens built on the lake that allowed them to sustain a population which, at its height, exceeded 200,000 inhabitants in Tenochtitlan alone.
These “floating islands” were built by weaving branches and roots over the shallow lake bed, then covering them with nutrient-rich mud. The system was so efficient that it allowed up to seven harvests a year, turning the region into the most productive granary in Mesoamerica.

Aztec society was organized in a complex hierarchy that, contrary to what many believe, allowed a certain social mobility based on merit, especially through military and religious service.
At the top was the Huey Tlatoani, the emperor, considered the representative of the gods on Earth. He was followed by the pipiltin, the hereditary nobility who held the main administrative and military posts. The pochteca, the long-distance merchants, formed a special class that enjoyed unique privileges due to their economic importance and their role as spies for the empire.
The base of the social pyramid was made up of the macehualtin, the free commoners who constituted the majority of the population and devoted themselves to farming, crafts and services. At the lowest rung were the tlacotin, slaves who, unlike in other slave systems, kept certain rights and whose children were born free.

The basic unit of social organization was the calpulli, a neighborhood or clan that functioned as a self-sufficient community. Each calpulli had its own lands, temple, school and leader. This organization not only made administering the empire easier, but also preserved local cultural identity and traditions.
The calpulli specialized in different activities: some devoted themselves to farming, others to specific crafts such as goldsmithing or featherwork, and some focused on military activities. This specialization created a web of interdependence that strengthened the social cohesion of the empire.
Aztec religion was a complex system that integrated deities and traditions from multiple Mesoamerican cultures. At the center of this pantheon were four main gods: Tezcatlipoca, the “Smoking Mirror”, god of night and conflict; Quetzalcoatl, the “Feathered Serpent”, deity of wind and wisdom; Tlaloc, the god of rain; and Huitzilopochtli, the solar and war god, specific patron of the Mexica.
Human sacrifices, although shocking to the modern mind, had a deep cosmological logic in Aztec thought. The Mexica believed that the gods had sacrificed themselves to create the world and humans, therefore, had to reciprocate with sacrifices to maintain the cosmic balance.
These ceremonies were not acts of barbarism, but highly codified rituals that followed precise astronomical calendars. The Templo Mayor was the main stage for these rituals, especially during festivities such as Xiuhmolpilli, the “New Fire” ceremony celebrated every 52 years.

The Aztec Empire was not a unified political entity in the modern sense, but rather a confederation of city-states that paid tribute to Tenochtitlan. This tribute system was extraordinarily efficient and was meticulously documented in codices that specified exactly which products, in what quantities and how often each province had to deliver.
Tributes ranged from basic goods such as maize, beans and chili, to luxury items such as quetzal feathers, jade, gold and cacao. This tributary diversity not only enriched the capital, but also created a complex exchange network that connected very different climatic and cultural regions.
The pochteca were much more than merchants; they were the eyes and ears of the empire in distant territories. Organized into hereditary guilds, they traveled in great caravans to regions as distant as Guatemala and Nicaragua, carrying Aztec products and importing raw materials and luxury goods.
Their strategic importance was such that they enjoyed special privileges: they had their own courts, could bear arms and, in many cases, their trading expeditions served as a pretext for future military conquests.

Contrary to stereotypes that portray them as warriors only, the Aztecs developed a rich literary and philosophical tradition. The tlamatinime, “those who know something”, were philosopher-poets who reflected on the nature of existence, beauty and truth.
The Nahuatl poetry that has come down to us reveals a refined aesthetic sensibility and a profound reflection on universal themes. Nezahualcoyotl, although technically not Aztec but Texcocan, exemplifies this intellectual tradition that flourished in the Valley of Mexico.
The Aztec education system was surprisingly advanced and universal. There were two main types of schools: the telpochcalli, for the children of commoners, where crafts, history and civic values were taught; and the calmecac, intended for the nobility, where a more sophisticated education was given that included writing, astronomy, theology and administration.
Both systems emphasized character formation, discipline and service to the community. Women also received education, although focused on domestic and religious activities.

In 1519, when Hernán Cortés landed on the Mexican coast, the Aztec Empire was at its height under the rule of Moctezuma Xocoyotzin. However, this encounter would mark the beginning of the end of one of the most brilliant civilizations in the Americas.
The conquest was not simply a Spanish military victory; it was the result of a complex combination of factors: the epidemics that decimated the native population, the alliances Cortés established with peoples hostile to the Aztecs, and the empire’s own internal contradictions.
The siege of Tenochtitlan lasted 93 days and ended on August 13, 1521 with the capture of the last tlatoani, Cuauhtemoc. The destruction of the city was systematic: the Spanish demolished temples, palaces and canals, using the materials to build the new Mexico City on the ruins of the ancient Aztec capital.

Although the Aztec Empire disappeared, its legacy lives on in many forms. Nahuatl, the language of the Aztecs, is still spoken by more than a million and a half people in Mexico. Words such as chocolate, tomato, avocado, coyote and chili passed from Nahuatl into Spanish and from there into other languages, demonstrating the persistence of their cultural influence.
In gastronomy, farming techniques, traditional medicine and syncretic religious festivities, elements of Aztec culture continue to be an integral part of modern Mexican identity.
The rediscovery of the Templo Mayor in 1978 in the heart of Mexico City’s historic center marked a rebirth of academic and popular interest in Aztec civilization. Every excavation reveals new aspects of their cultural and technological complexity, forcing historians to constantly revise their interpretations.
Recent finds, such as the offerings found in the Templo Mayor, continue to provide evidence of the sophistication of their trade networks, their astronomical knowledge and the complexity of their religious rituals.
The Aztecs left us more than pyramids and treasures; they left us an example of how a society can rise from the humblest origins to create one of the most sophisticated civilizations in the world. Their ability to integrate diverse cultural traditions, develop innovative technologies and create a complex yet efficient political system makes them eternal masters of civilization.
Their history teaches us that true power lies not only in military force, but in the ability to create lasting institutions, foster education, develop art and maintain a balance between the material and spiritual needs of society.
Today, as we face our own global challenges, we can learn from Aztec wisdom: their respect for nature, their emphasis on education, their ability to integrate cultural diversity and their understanding that a truly great civilization is one that cares for both the well-being of its citizens and its legacy for future generations.
