Explanation by stage of the timeline in the history of the Aztec empire

I. Origins in Aztlán (Mythical Era)

The Aztecs believed they originated from Aztlán, a northern island homeland shrouded in mystery. Scholars suggest Aztlán was located north of the Valley of Mexico. The Aztecs were a migratory tribe composed of seven distinct groups, journeying south in search of their prophesied land.

II. Early Stops: Culhuacán and Chicomoztoc.

During their migration, the Aztecs paused at Culhuacán (“curved mountain”) and Chicomoztoc (“place of seven caves”). These locations are believed to lie northeast of the Valley of Mexico.

This period was marked by internal conflicts, as the tribe struggled to unify under the leadership of Huitzilopochtli, who would later be deified as their chief god.


III. The Conflict at Coatepetl

The Aztecs faced internal divisions, including a significant clash at Coatepetl. According to legend, Huitzilopochtli personally defeated the goddess Coyolxauhqui in battle, dismembering her body.

This pivotal event inspired the creation of the Templo Mayor in Tenochtitlán, where a statue of Coyolxauhqui’s dismembered form was later discovered by archaeologists.

IV. Settlement at Chapultepec and Exile

Arriving in the Valley of Mexico, the Aztecs settled in Chapultepec, only to face attacks from neighbouring city-states. After the death of Copil, a rival leader, the Aztecs fled to the swampy lands of Lake Texcoco. According to legend, they saw an eagle perched on a cactus, a divine sign that led them to found Tenochtitlán in 1325 AC.

V. Formation of the Triple Alliance

By 1426 AC, the Aztecs allied with Texcoco and Tlacopan to create the Triple Alliance, defeating the Tepanecs after a 114-day siege. Leaders like Itzcoatl, Moctezuma Ilhuicamina, and Tlacaelel played key roles in this strategic partnership, which enabled the Aztecs to expand their empire through warfare and marriage alliances.

VI. Expansion and Internal Challenges

The Aztecs launched military campaigns to expand their empire, subjugating tribute-paying cities and establishing long-distance trade routes. However, internal challenges persisted:

  • Rebellions arose under weak rulers.
  • Groups like the Tlaxcalans and Tarascans resisted Aztec control.
  • Strict laws imposed by Montezuma Xocoyotzin exacerbated tensions with subjugated cities.

VII. Arrival of the Spanish

In 1519 AC, Hernán Cortés arrived in the Valley of Mexico. Some Aztecs believed Cortés to be the returning god Quetzalcoatl, based on a prophecy. Montezuma II sent gifts to Cortés, hoping to establish peace, but these offerings encouraged the Spanish to march on Tenochtitlán. Cortés allied with Aztec enemies, including the Tlaxcalans, and advanced toward the capital.

VII. The Fall of Tenochtitlán

In 1521 AC, after months of siege and devastating outbreaks of smallpox, Tenochtitlán fell to the Spanish. The city’s destruction marked the end of the Aztec Empire. Cuauhtémoc, the last Aztec ruler, was captured and executed. On the ruins of Tenochtitlán, the Spanish built Mexico City, ushering in a new era of colonization.
