Who Built Teotihuacán, One of the Largest Ancient Cities in Mesoamerica?

Just outside Mexico City lies another metropolis, constructed not out of concrete and glass but of native stone. Its massive, stepped pyramids rise hundreds of feet above the broad floor of the Valley of Mexico. These pyramids tower over ancient ceremonial grounds and the ruins of what was once a powerful, thriving city.

Teotihuacán is one of the most impressive ancient sites in all of Central and North America. Its scale surpasses the cities built by the Maya and other Mesoamerican civilizations. Though most notable for the Pyramids of the Sun and Moon, and the three-mile-long Avenue of the Dead they overlook, Teotihuacán was also a bustling, cosmopolitan city. Excavations have revealed numerous apartment complexes that could have held up to a hundred people each, as well as evidence that intermingled ethnic groups from all over Mesoamerica once resided in the city.

The city’s rulers held sway over a large part of the Valley of Mexico, and perhaps even influenced civilizations much farther away. For hundreds of years, Teotihuacán would have been one of the pre-eminent population centers of the Mesoamerican world — a place of wealth, power and culture.

But despite its obvious cultural and political significance, and well over a hundred years of archaeological research, we still don’t know many basic facts about the city. The identity of its builders remains a mystery, as does the language they spoke and how their government was organized. Though Teotihuacán’s might and significance are plain to see, the city does not easily yield up its secrets.

When Was Teotihuacán Built?

Teotihuacán was built more than two thousand years ago, and was a flourishing city by the second century A.D. The city itself was built according to a rigorous design plan — it is laid out geometrically, and features a complex network of irrigation canals drawn from the nearby San Juan river. Though the city center, with its massive temples, is the most stunning feature of the site, a robust urban hive surrounded the ceremonial plaza. At least 2,000 dwellings have been uncovered, and the city likely housed more than 100,000 inhabitants at its peak. That would have made Teotihuacán the sixth-largest city in the world at the time.

Teotihuacán was inhabited until around 700 A.D. What led the residents to leave — drought, famine, warfare — is unknown. But even after it lay empty, the city’s scale and impressive monumental structures lent it an aura of magnificence. Centuries later, the Aztecs came to view Teotihuacán, long-abandoned, as a sacred site. They would even hold rituals in its center. The city’s name today comes from the Aztec and translates as “the place where the gods were created.”

The temples are notable for the distinctive talud-tablero style of architecture, which features alternating slopes and panels to create the unique stepped pyramids of Teotihuacán. The Pyramid of the Sun has a base almost as large as that of the biggest Egyptian pyramid, and is nearly 200 feet tall. It’s likely the inhabitants of the city held rituals and ceremonies at the pyramids, as recent finds suggest. One chamber in the Pyramid of the Moon held valuable offerings like obsidian, pyrite, ceramics, and textiles, as well as the bodies of a number of people, most of them decapitated.

Teotihuacán culture spread far beyond the city itself. Talud-tablero-style temples are found in the Maya city of Tikal, some 700 miles away. Based on Maya inscriptions there, archaeologists think that warriors from Teotihuacan may have invaded the powerful Maya city-state in A.D. 378. Maya inscriptions note the death of the city’s leader, Jaguar Paw, on the same day as the arrival of a powerful warrior from a distant city. That and other evidence led archaeologists to surmise that Teotihuacan may have sent its armies hundreds of miles away to capture one of the jewels of Maya civilization.

But relationships between the Maya and Teotihuacán were not always so violent. There’s also evidence of Maya murals and art in the city, and that members of that society inhabited the city, though whether as diplomats or inhabitants is unclear. But their presence is indicative of the cosmopolitan nature of Teotihuacan. The city was probably filled with people from multiple cultures in Mesoamerica, living and working together.

It also makes the question of who, exactly, the Teotihuacán people were more complex. Scholars once suggested they may have included the Toltecs, a civilization that inhabited roughly the same region as Teotihuacan for hundreds of years. But others note the Toltecs didn’t flourish as a civilization until long after the city had declined, making them an unlikely choice. Others have suggested the Totonacs, a culture about which less is known, though Totonac descendants still live in Mexico today.

Another theory is that the city’s genesis came about as the result of a natural disaster, perhaps a volcanic eruption, that forced many people from their homes. Coming together in a place of safety, these refugees may have banded together to create a new city for themselves. The residents of Teotihuacán, then, may not have belonged to any particular group. Instead, they made their own, along with a new city to house them.

Ongoing Mysteries of Who Built Teotihuacán

One thing that’s made it difficult to learn about Teotihuacán is the absence of a formal written language. By contrast, the Maya, along with other Mesoamerican peoples, used a formalized written script, and left thousands of inscriptions and other texts for archaeologists to study.

While the people of Teotihuacán did use a written notational system, it doesn’t appear to constitute an actual language. For this reason, archaeologists still don’t know what language (or languages) the city’s residents spoke.

Also unclear is how the city was governed. Though the impressive physical organization of the city attests to a clear power structure, there’s little evidence of actual rulers. We know about the leaders of other civilizations like the Maya and the Aztec from the copious inscriptions and artwork they produced about their god-like rulers. Teotihuacán has none of that. It’s led some archaeologists to suggest the city may have been governed by a council, or some other more distributed form of leadership.

Clearly, puzzling facets of Teotihuacán culture remain to be answered. But new finds are still emerging. In 2003, a heavy rainstorm opened up a large sinkhole near the Temple of the Plumed Serpent. When archaeologists descended into the chasm they found themselves in a secret tunnel underneath the central plaza. It led to a room filled with offerings: seashells, cat bones, pottery, fragments of human skin and more, Smithsonian reports. The finds represent new opportunities for research and understanding — and along with future discoveries at the site, perhaps they’ll finally unlock the true history of Teotihuacán once and for all.
