8.3.1 The Aztec Empire

The early origins of the Aztecs are cloudy, partly because this culture did not have a fully developed writing system for chronicling its history. Instead, the Aztecs relied on artistic records and oral traditions passed from generation to generation. They also used codices, book-like records drawn on bark paper that combined both images and pictograms. Based on information from these sources, historians have been able to place Aztec origins within the context of the collapse of the Toltec civilization.

The Toltec were an earlier Mesoamerican culture that filled the power vacuum created by the decline of Teotihuacán. From their capital at Tula, the Toltec dominated central Mexico between the tenth and twelfth centuries CE. When their civilization collapsed internally or was possibly conquered, a number of nomadic and warlike groups descended into the area, one of which appears to have been the Aztecs. A new period of cultural transformation and violent wars followed. The Aztecs clearly excelled in these military conflicts, likely acting as mercenaries. Ultimately, they were permitted to settle on a collection of islands within a large but shallow ancient lake called Lake Texcoco, one of five contiguous lakes that once spread across the Valley of Mexico.

Beyond the Book

The Aztec Origin Story

Much of our information about the Aztecs was recorded by the Spanish after they arrived in the sixteenth century. This is problematic for historians because Spanish religious leaders and conquistadores destroyed Indigenous records, particularly those that seemed to have religious significance. Since the Europeans viewed the Indigenous people through their own worldview and transformed Mesoamerica politically and culturally, their written accounts are often an imperfect means for understanding this people. Only by carefully studying the records we have, including Spanish accounts and Aztec codices, have scholars been able to piece together the story the Aztecs told themselves and their subject peoples about their origins.

The word Aztec is derived from their mythical original home, Aztlan. According to the Aztecs’ own origin story, they migrated from Aztlan centuries before their rise to greatness in the Valley of Mexico. This long period of wandering in search of a new home included a number of important events, such as battles, encounters with sorcerers, significant tribal divisions, and the birth of important gods like Huitzilopochtli, the Aztec war god. The story culminates in a dramatic clash on the shore of Lake Texcoco. There the Aztec migrants faced an alliance of rebels who sought their destruction. They survived only because Huitzilopochtli intervened by sending his priests to kill the leader of the enemy alliance and rip out his heart. Huitzilopochtli then instructed the Aztec priests to throw the heart far into the lake. It landed on the island of Tenochtitlán and sprouted a cactus, on which an eagle holding a snake landed. This was where Huitzilopochtli said the Aztecs should settle and build their great city (Figure 8.27).

While archaeological evidence contradicts some of this legend, origin stories do have special cultural and political significance. Not only did the Aztecs’ migration story reinforce the important idea that they had emerged from obscurity to dominate the world, but different leaders also curated the history regularly to demonstrate that their reign was the culmination of earlier events. In this way, the story could change over time to support different rulers, general Aztec dominance, and specific cultural practices.

• Why might the Aztecs have wanted to emphasize that they came from a distant land?
• What other practical purposes might such an origin story serve?

The Aztecs began constructing their home city of Tenochtitlán among the islands within Lake Texcoco around 1325. During the following century, they survived by trading goods they could produce as well as continuing to serve as mercenaries for the surrounding powers. In this way, they accumulated wealth and supplied themselves with stone, which they used to transform their small island settlement into a large and architecturally sophisticated city. After acquiring some influence in the region, they formed an alliance with two neighboring city-states, Texcoco and Tlacopan. Then, in 1428, this Triple Alliance launched a surprise attack on the powerful city-state of Atzcapotzalco and made itself the dominant regional power. Over the next several decades, the Triple Alliance, with the Aztecs at its head, expanded its control of central Mexico to include Oaxaca in the west, parts of modern Guatemala in the south, and the areas bordering the Gulf of Mexico. By 1502, the newly crowned emperor of the Aztecs, Moctezuma II, was ruling an expansive empire from his capital city of Tenochtitlán (Figure 8.28).

At its height in the early 1500s, Tenochtitlán had a population of at least 200,000 people. It was a massive island city with large causeways that connected it to the shores of the lake. Some of the city’s land had been made by human intervention, which included creating artificial agricultural islands called chinampas around the city that were crisscrossed by canals for irrigation and transportation. These chinampas produced food for the city’s occupants. Toward the center of the island where the land was more firm were the homes of the city’s occupants, made mostly of adobe with flat roofs and built around small courtyards. At the center of the island were large temples, a ball court, administration buildings, homes for the elite, and the palaces of the rulers. The most impressive of the temples was the Templo Mayor, which was expanded numerous times during its long history. By the early 1500s, it was a dual stepped pyramid standing about ninety feet tall (Figure 8.29). One side was dedicated to the city’s patron Tlaloc, the god of rain. The other side was dedicated to Huitzilopochtli, the god of war. Priests climbed a long staircase to the temple to perform important state rituals.

One of the most important ceremonies performed at the Templo Mayor and other temples in Tenochtitlán was the ritual of human sacrifice. Like many Aztec traditions, this rite was widely practiced in Mesoamerica and had roots going back to the Olmec culture and likely earlier. Human sacrifices occurred on important days identified on the Aztec calendar and during the commemoration of new temples or the expansion of existing ones. Contemporary descriptions note that long lines of sacrificial victims were led up the steps to the temple platform. There they were laid on a sacrificial stone, where their chests were opened with a sharp flint or obsidian knife and their hearts removed by the executioner (Figure 8.30). The bodies were then tossed down the steps of the temple.

These rituals were closely tied to Aztec cosmology and the people’s understanding of their role in the universe. The gods were believed to participate in the practice of sacrifice and to have used it to create the world and perpetuate its existence (Table 8.2). They often needed the assistance of human beings, who were created to serve and feed them through human sacrifice and other means. The sacrifices were thought to ensure that the sun stayed in the sky, the harvests continued to be bountiful, illnesses were kept at bay, and the military power of the Aztecs remained supreme.

Human sacrifice was also an important means of preserving and expanding the empire and keeping conquered territories in line, since sacrificial victims were often those captured in battle. Thus, the goal in warfare was often to seize the enemy alive. Aztec war had important ritual purposes too. In some instances, it could be highly theatrical and consisted of paired individuals fighting each other, rather than large armies. Young boys began training to serve in the Aztec military from an early age. They drilled regularly with javelins for throwing, leather-covered shields, and clubs fitted with obsidian blades. Until they were old enough and experienced enough to become warriors themselves, they worked in the service of veteran warriors (Figure 8.31).

The Aztec Empire also exacted tribute payments from its conquered territories. At its height, the empire consisted of thirty-eight provinces, each expected to submit specific tribute to the imperial capitals. Occasionally, regions that resisted incorporation into the empire were given harsh terms. More often, the type of tribute demanded was related to the location of the tribute state and the goods it typically produced. For example, the Gulf coast area was known for natural rubber production and was assessed a tribute payment of sixteen thousand rubber balls for use in the Aztec ball game. Locations much closer to the capitals commonly provided goods like food that were expensive to transport over long distances. Those much farther away might be expected to provide luxury goods the Aztec elite gave as gifts to important warriors. Typical tribute items included cloth, tools like knives and other weapons, craft goods of all types, and of course, food. Tribute items could also include laborers to work on larger imperial projects. The Aztec tribute system functioned much like a crude system of economic exchange. Goods of all types flowed into the centers of power and the hands of elites. But they also made their way to commoners, who benefited from the diversity of the items the system made available.

As a highly militarized society, Aztec culture prized perceived male virtues like bravery, strength, and fighting ability. Warriors were expected to sacrifice themselves to perpetuate the glory of the state. When they were successful in battle, they were adorned with rich cloth and celebrated by the masses. Aztec women operated within a more circumscribed world. They could not serve in the military or attain high positions within the state, yet they did not necessarily occupy a lower status than men. Rather, Aztec state culture emphasized the complementarity of women and men, with men expected to fill roles outside the home like farming and fighting and women responsible for domestic chores like cooking and weaving.

Aztec women thus often spent long hours grinding corn into meal and weaving clothing for the family. Their work could sometimes take them outside the home, such as to the markets where some gained considerable wealth as traders and served in leadership roles. As midwives and healers, women ensured that healthy children were born and that the sick were treated with medicines backed by centuries of knowledge about the medicinal properties of certain plants.

Aztec society was made up of a number of social tiers. At the bottom was a large number of enslaved people and commoners with no land. Above these were the commoners with land. Before the imperial expansion, landed commoners had some limited political power. However, within the imperial system they were relegated to providing food and service for the military. Above them were the many specialized craftspeople, merchants, and scribes. And above all commoners were the nobles, who used conspicuous displays of wealth to elevate themselves. They served in the most important military positions, on the courts, and in the priesthood.

The members of the Council of Four also came from the noble class. The council’s primary task was to select the Aztec emperor, or Huey Tlatoani, from the ranks of the nobility. The emperor occupied a position far above everyone else in Aztec society. His coronation included elaborate rituals, processions, speeches, and performances, all meant to imbue him with enormous power. Even high-ranking nobles were obliged to lie face down in his presence.

The Aztec rulers had not always been so powerful or elevated so far above the masses. Their great authority and the ceremony of their office increased with the expansion of the empire. By the coronation of Moctezuma II in 1502, the office of emperor had reached its height, as had the empire. The expansion of the preceding decades had slowed, and demands for tribute and captives for ritual sacrifice were taking their toll and stirring resentment in many corners of the empire. It was into this context that the first Spanish explorers came. They were able to exploit the weaknesses in the empire and eventually bring about a new Spanish-centered order built on top of the old Aztec state.
