Teotihuacan Pyramids Timeline

Across from the Ciudadela, the Great Compound likely functioned as the city's main market and distribution hub. It anchored the economic engine that sustained a population that eventually exceeded 100,000 people.

Control of the Pachuca green obsidian sources allowed Teotihuacan to mass-produce blades, eccentrics, and ornaments for export. Workshop districts within the city employed thousands of artisans, making obsidian trade a pillar of the state's wealth and influence.

Unlike most ancient cities, Teotihuacan housed the majority of its residents in multi-family stone apartment compounds such as Tetitla and Tepantitla. These complexes featured murals, drainage systems, and courtyards, indicating a remarkably organized urban society.

The famous murals of the Tepantitla compound portray the 'Paradise of Tlaloc,' a flowering realm of streams, butterflies, and playing figures. They offer rare insight into Teotihuacan religious beliefs and everyday imagery of abundance.

Excavations of the Merchants' Barrio revealed a neighborhood of immigrants from Monte Albán who retained Oaxacan burial customs and pottery styles. Their presence attests to Teotihuacan's role as a cosmopolitan magnet drawing people from distant regions.

In January 378 AD, a warlord associated with Teotihuacan named Siyaj Kʼakʼ arrived at Tikal, and the new king Yax Nuun Ahiin II took the throne. Maya monuments depict these rulers with Teotihuacan weapons and regalia, marking dramatic intervention in the Maya lowlands.

Yax Nuun Ahiin, son or protégé of a Teotihuacan figure called Spearthrower Owl, ruled Tikal with strong Central Mexican symbolism. This episode demonstrates that Teotihuacan projected political power hundreds of kilometers beyond its core territory.

At its height, Teotihuacan was among the largest cities in the world, covering about 20 square kilometers. Its multiethnic population included enclaves of Zapotec migrants from Oaxaca and merchants from the Gulf lowlands, reflecting far-reaching exchange networks.

The founder of Copán's dynasty, K'inich Yax K'uk' Mo', is depicted with Teotihuacan-style goggles and weapons, having arrived via Teotihuacan-linked routes. The event shows the metropolis's ideology reshaping royal legitimacy deep in southeastern Mesoamerica.

During the fifth century, Teotihuacan dominated trade routes for obsidian, cacao, jade, and quetzal feathers, and its iconography appeared from Guatemala to western Mexico. Whether through conquest, alliance, or commerce, its cultural footprint spanned much of Mesoamerica.

This elite residence, named after carved quetzal-butterfly pillars, showcases fine craftsmanship with intricate reliefs and painted murals. It exemplifies the luxurious lifestyle of Teotihuacan's ruling class at the city's zenith.

Climate episodes linked to global events around 536 AD brought cooler, drier conditions that reduced harvests. Combined with ecological stress, these droughts likely undermined the food supply sustaining Teotihuacan's enormous population.

After centuries of growth, Teotihuacan's population dwindled as trade networks frayed and elite institutions failed. Possible contributing factors include drought, soil degradation, resource depletion, and the loss of tributary relationships.

Around the mid-sixth century, key structures including the Temple of Quetzalcoatl were deliberately burned, likely signaling internal revolt or the collapse of central authority. The targeted destruction suggests popular uprising against elites rather than foreign invasion.

By the eighth century the metropolis had lost its dominant role; power shifted to centers like Cacaxtla, Xochicalco, and El Tajín during the Epiclassic period. Small groups continued living among the ruins, but the era of Teotihuacan greatness had ended.

The Toltec capital of Tula adopted architectural motifs and legends connecting itself to Teotihuacan. Later Mesoamerican peoples revered the ruined city as the mythical Tollan, the place where gods and civilization originated.

Arriving in the Basin of Mexico, the Mexica encountered the vast abandoned city and named it Teotihuacan, meaning 'the place where the gods were created.' They incorporated it into their origin mythology and made pilgrimages to its pyramids.

Mexican archaeologist Leopoldo Batres led the first systematic excavations, restoring parts of the Pyramid of the Sun for the centennial of Mexican independence. His controversial restorations nonetheless brought international attention to the site.

Manuel Gamio pioneered scientific stratigraphic archaeology at Teotihuacan, mapping the Avenue of the Dead and clarifying the site's chronology. His work established the foundation for all subsequent research at the ancient metropolis.

UNESCO inscribed the Pre-Hispanic City of Teotihuacan as a World Heritage Site, recognizing its universal value as one of Mesoamerica's greatest achievements. The designation supports conservation and draws millions of visitors each year.

Heavy rainstorms exposed a sinkhole revealing a sealed tunnel running under the Feathered Serpent Pyramid. INAH archaeologist Sergio Gómez Chávez launched a painstaking exploration of the passage and its chambers of ritual offerings.

Robots and careful manual excavation revealed liquid mercury pools, jade figurines, shells, and rubber balls inside the tunnel, interpreted as a recreation of the underworld. The discoveries suggested a possible royal tomb may still lie undiscovered below the pyramid.
