Aztec (Mexica) religion

Overview

Aztec (Mexica) religion was the state religion of the Nahuatl-speaking empire centred on Tenochtitlan, in what is now Mexico City, from the 14th century until the Spanish conquest of 1521. Its cosmology, which pictured the present world as the last of several creations, and its calendar system were shared in broad outline with other Mesoamerican peoples, including the Maya. Its pantheon numbered dozens of gods, led by the war god Huitzilopochtli, the rain god Tlaloc and the feathered serpent Quetzalcóatl, and held that the sun depended on human blood to keep moving. A large priesthood ran an elaborate ritual calendar at the twin-pyramid Templo Mayor, and human sacrifice, particularly of war captives, was a routine, religiously framed practice. As an organized state cult it ended with the conquest, and what is known of it comes mostly through Spanish-era, often missionary, writers.^{[1–3, 5–11]}

History

Migration and the founding of Tenochtitlan c. 1325

By Aztec tradition, the god Huitzilopochtli led the wandering Mexica to settle where they would see an eagle perched on a cactus; they found the sign on a small, marshy island in Lake Texcoco, and there, in 1325, they built a temple and the first houses of Tenochtitlan, a name meaning roughly "by the prickly-pear fruits." A simple shrine to Huitzilopochtli on that spot became the first version of the Templo Mayor.^[12–13]

Empire and the Templo Mayor 1428–1519

After 1428 the ruler Itzcóatl allied Tenochtitlan with Texcoco and Tlacopan in the Triple Alliance, and conquest and tribute built a vast empire. Archaeological excavation has shown that successive rulers enlarged the Templo Mayor across seven building phases, one temple always honouring Tlaloc and the other Huitzilopochtli. Religion and statecraft were inseparable: war supplied the captives whose hearts and blood, offered to the sun, were held to keep the cosmos from collapsing.^[14–16]

The Spanish conquest 1519–1521

Hernán Cortés reached central Mexico in 1519 with a small Spanish force, steel weapons, horses, and thousands of allied warriors drawn from peoples the Aztecs had conquered. He took the ninth ruler, Motecuhzoma II, prisoner; Motecuhzoma died in Spanish custody, and his successors could not hold the city against a two-year campaign worsened by European epidemic disease. Tenochtitlan fell on 13 August 1521, and with it the Aztec empire and its state cult.^{[7, 17–18]}

After the conquest 16th century–present

Spanish friars destroyed temples and most pre-conquest religious books, but some, including the Franciscan Bernardino de Sahagún, also recorded Aztec belief and ritual in detail by interviewing Nahua elders, producing the bilingual Florentine Codex. No organized Aztec state religion survived the conquest, but Nahuatl itself did: it is still spoken by over a million people in Mexico today.^{[6–7, 19–20]}

Beliefs

Five Suns · Nahui Ollin

the present, fifth sun

Aztecs held that the world had already been created and destroyed four times, by flood, earthquake, and wind, with a fifth and final destruction yet to come. Quetzalcóatl, sole survivor of the Wind Sun, was credited with bringing civilization to humanity, and with the self-sacrifice that let the bones of the dead give birth to a new people.^[21–22]

teotl

a sacred or divine force

Aztec religion recognized dozens of distinct divine forces, or teotl, including the paired creator Ometeotl and the shape-shifting Tezcatlipoca, alongside Huitzilopochtli, Tlaloc and Quetzalcóatl; the pantheon absorbed deities from the many peoples the Aztecs ruled or traded with.^[9]

nextlahualli

a debt payment to the gods

Aztecs believed human existence was a debt owed to the gods, repaid above all through the sun god's need for blood. War against neighbouring states was framed partly as a religious duty to capture victims for sacrifice, so that the sun would keep moving and the world would not end.^[10]

Practice

Sacrifice and bloodletting

Heart sacrifice, usually of a war captive, offered to the sun god Tonatiuh at the Templo Mayor, was the best-known Aztec rite; priests and worshippers also practised bloodletting from their own bodies as an offering. Modern historians stress that, alongside its religious logic, warfare and sacrifice also served Aztec politics, demonstrating and enforcing imperial power.^{[11, 23]}

The calendar round

Priests ran ceremonies keyed to two interlocking calendars: a 260-day tonalpohualli used mainly for divination and a 365-day solar xiuhpohualli of eighteen 20-day months plus five unlucky days. The two cycles realigned only once every 52 years, an event treated as the calendar's most important turning point.^[24]

Priesthood

Each god and temple had its own order of priests, headed at Tenochtitlan by the high priests of Huitzilopochtli and Tlaloc, within what Spanish observers described as one of the most elaborate institutions of Aztec life. Priests carried out the blood sacrifices and offerings at the centre of public ritual.^[25]

Holy days

New Fire Ceremony · toxiuhmolpilia

every 52 years, when the two calendars realign

Marking the rare moment when the 260-day and 365-day calendars returned to the same alignment, this ceremony renewed the Aztec world for another 52-year cycle, treated as the most important single date in the calendar round.^[4]

Veintena festivals

each of the eighteen 20-day months of the solar year

Each 20-day month of the solar calendar carried its own public festival, with ritual bathing, offerings, sacrifices, and masked dances and processions re-enacting the deeds of the gods, performed by priests before the assembled population.^[24–25]

People

Scripture

Florentine Codex

compiled c. 1545–1590

A bilingual Nahuatl–Spanish encyclopedia of Aztec life and religion compiled by Bernardino de Sahagún from interviews with Nahua elders; despite its missionary framing, it remains the richest single source on Aztec gods, ritual and the calendar.^[6]

Ritual codices · amoxtli

Painted books recorded the 260-day tonalpohualli and its presiding gods for priests to use in divination; very few painted books from before the conquest survive today, most having been lost or destroyed.^{[19, 28]}

Places

The twin-pyramid main temple of the Aztec capital, dedicated to Huitzilopochtli and Tlaloc, built up over seven phases from a simple 1325 shrine; its ruins, including the carved Coyolxāuhqui stone, lie within Mexico City's UNESCO-listed historic centre.^{[2, 13, 15, 29]}

Teotihuacan

MEX · UNESCO World Heritage, 1987

A vast pre-Aztec city, abandoned centuries before the Aztecs rose, whose pyramids and Temple of Quetzalcóatl the Aztecs revered as a sacred site tied to the creation of the sun and moon in their own mythology.^[21]

How we know

Colonial sources and their bias

Almost everything known about Aztec religion comes filtered through the conquest: Spanish friars destroyed nearly all surviving painted books, and the richest surviving account, Sahagún's Florentine Codex, was compiled decades later by a missionary working with Nahua informants who had their own reasons to shape what they told him. Historians read these sources critically, cross-checking them against the handful of surviving codices and archaeology.^{[6, 19, 28]}

Archaeology at the Templo Mayor

Excavation of Mexico City's Templo Mayor has uncovered the enormous carved Coyolxāuhqui stone and 124 buried ritual offering caches confirming the temple's dual dedication to Huitzilopochtli and Tlaloc, giving archaeologists physical evidence that complements, and sometimes corrects, the colonial-era written accounts.^{[2, 29]}
