Ancient Maya Metropolis | Full Documentary | NOVA | PBS

Overview

LiDAR mapping, cave climate records, high-precision radiocarbon dating, and Maya hieroglyphs reveal how Caracol grew into a metropolis of roughly 100,000 people and how drought, political strain, warfare, and changing social conditions contributed to the gradual abandonment of Southern Maya cities. Archaeologists and Maya researchers including Jaime Awe, Diane and Arlen Chase, Julie Hoggarth, and Iyaxel Cojti Ren also show that abandonment was a transition—not the disappearance of the Maya, whose communities and traditions continue today.

Key takeaways

LiDAR transformed Caracol’s known scale: combining laser mapping with the Chases’ ground surveys revealed more than 7,000 raised household structures, compared with 78 previously mapped structures.
Caracol’s estimated population of about 100,000 around 700 CE made it one of the world’s largest cities, supported by terraced agriculture, household networks, roads, and nearby markets.
Cave isotope records indicate roughly 50 years of sharply fluctuating rainfall beginning around 750 CE, followed by nearly a century of severe drought in the ninth century.
Bone collagen analysis shows Maya diets became less diverse as populations increasingly depended on corn, making communities more vulnerable when drought disrupted rainfall-dependent crops.
The Komkom vase preserves a rare day-by-day account of warfare in 799 CE, including Naranjo’s attacks on Sak Suutz’ and Yaxha, and was deposited in 812 as royal authority at Baking Pot ended.
The abandonment of Southern Maya cities was a prolonged transition shaped by multiple pressures, including drought, warfare, economic decline, and social inequality; Maya people and culture endured, with populations also shifting toward thriving Northern cities.

0:00 Ancient Maya Cities and the Questions of Their Abandonment

The Maya built pyramids, temples, cities, and a readable hieroglyphic writing system across Central America over roughly 2,000 years.
By about 900 CE, many major Southern Maya cities had been abandoned, raising questions about urban life, agriculture, and migration.
The documentary introduces evidence from aerial mapping, cave deposits, human remains, and inscriptions to investigate Maya history.

4:11 Maya Archaeology, Living Descendants, and Colonial Erasure

Francisco Estrada-Belli describes the Southern Maya Lowlands as a tropical region spanning parts of Mexico, Guatemala, Belize, and neighboring countries.
Iyaxel Cojti Ren identifies herself as a K’iche’ Maya woman and notes that at least 30 Maya ethnolinguistic groups exist today.
Jaime Awe and conservator Jorge Can connect archaeological work with Maya community heritage and preservation.
Spanish colonial narratives falsely separated contemporary Maya people from the builders of ancient cities, while religious suppression helped erase knowledge of hieroglyphic writing.

9:41 LiDAR Reveals More Than 7,000 Caracol Households

Diane and Arlen Chase began mapping Caracol by hand in 1985, but two decades of work captured only a fraction of the city.
LiDAR sends laser pulses through forest canopy and measures their return to create detailed ground maps beneath the jungle.
Arlen Chase’s team combined LiDAR with years of ground surveying; the mapped count expanded from 78 structures to more than 7,000 raised household structures.
Around 700 CE, Caracol may have held 100,000 residents, making it the seventh-largest city in the world by some estimates.

14:28 Caracol’s Family Plazuelas, Food Production, and Trade

Caracol’s hillside plazuelas grouped extended-family homes around plazas, with stone foundations supporting pole-and-thatch buildings.
Households had nearby terraced fields for corn, beans, and squash; residential groups also contained mortuary shrines and ritual caches.
A finely decorated cylinder vase found in a modest residential crypt shows that master-quality art was not limited to elite tombs.
Roads connected homes and markets, while traditional foods such as tortillas and tamales made from corn link present-day Maya practices to the past.

19:36 Divine Kings, Maya City-States, and Caracol’s Decline

Maya rulers called ajaw—and, for especially powerful rulers, k’uhul ajaw—combined political authority with religious roles as intermediaries to the gods.
Stelae recorded royal legitimacy, while trade and alliances linked city-states such as Caracol, Tikal, and Calakmul.
Caracol’s downtown burned around 895 CE; evidence at the royal palace includes a young child left unburied and weapons on the floor.
The abandonment of Southern Maya cities began unevenly around 750 CE, alongside the end of monumental construction and the weakening of trade networks.

24:25 Cave Isotopes and Bone Dating Trace Drought and Diet

Stalagmites from Yok Balum Cave preserve annual chemical layers; oxygen isotopes indicate changes in rainfall, while uranium-thorium measurements help date them.
The cave record shows volatile wet and dry conditions beginning around 750 CE, followed by nearly a century of severe drought in the ninth century.
Julie Hoggarth uses high-precision radiocarbon dating, accurate to roughly 15–20 years before calibration, to establish when individuals lived.
Stable isotopes from bone collagen reveal diet: as cities expanded, Maya communities relied increasingly on corn, a crop requiring land and dependable precipitation.

30:31 Drought, Royal Ritual, and Intensifying Maya Warfare

As drought threatened harvests, rulers faced pressure to fulfill their religious role as rain-bringers and increasingly turned to ritual activity.
Maya bloodletting was intended to restore cosmic balance, while rulers also brought offerings into caves believed to house deities such as the rain god.
In Actun Tunichil Muknal, Jaime Awe documented vessels deliberately broken or “killed” as offerings; radiocarbon evidence links increased cave ritual to the cities’ decline.
Warfare accelerated after about 750 CE, adding political conflict and social antagonism to environmental and economic pressures.

36:39 The Komkom Vase: A Rare Historical Record from 799 CE

A 2015 excavation at Baking Pot uncovered a deposit of smashed high-quality artifacts near the entrance to the royal palace.
The Komkom vase was reconstructed from 86 shards and contains the longest hieroglyphic text known on a Maya vase.
Its account, describing events from February 799 CE, offers an unusually close-dated record of conflict during a period of Southern Maya instability.
Iyaxel Cojti Ren and other Maya epigraphers teach glyph reading through workshops, helping contemporary Maya communities reconnect with ancestral writing.

43:35 The Komkom Vase’s Account of the Naranjo–Yaxha War

The inscription follows a power struggle between Kanot Awhil of Naranjo and K’inich Lakamtuun of Yaxha, neighboring rulers with family ties.
It records a ceremonial fire in Naranjo on February 19, 799, followed two days later by the burning of Sak Suutz’.
Months later, Naranjo attacked Yaxha; its ruler fled to a mosquito-infested place, and the account ends with a victory dance on September 3, 799.
Dedicated in 812 CE, the vase was deposited at Baking Pot as royal kingship at the site was ending.

48:34 Southern Maya Abandonment as Migration and Cultural Transition

Southern city abandonment unfolded over time: monumental inscriptions ceased, elites departed, and communities moved rather than leaving all at once.
Diane Chase describes growing inequality at Caracol, where access to goods narrowed and commoners faced greater demands from the ruling system.
While Southern Lowland cities lost population, Northern Maya cities expanded and received migrants; Maya civilization continued there for centuries.
Despite colonial disease, violence, and religious conversion, millions of Maya people remain across Guatemala, Mexico, Belize, Honduras, and El Salvador, sustaining Maya languages and traditions.
