The Aztec Triple Alliance or Aztec Empire began as an alliance of three Nahua city-states or "altepetl": Tenochtitlan, Texcoco, and Tlacopan. These city-states ruled the area in and around the Valley of Mexico from 1428 until they were defeated by the Spanish conquistadores and their native allies under Hernán Cortés in 1521.
The Triple Alliance was formed from the victorious faction in a war between the city of Azcapotzalco and its former tributary provinces. Despite the initial conception of the empire as an alliance of three cities, Tenochtitlan quickly established itself as the dominant partner. By the time the Spanish arrived in 1520, the lands of the Alliance were effectively ruled from Tenochtitlan, and the other partners in the alliance had assumed subsidiary roles.
The alliance waged wars of conquest and expanded rapidly after its formation. At its height, the alliance controlled an empire that covered most of central Mexico as well as some more distant lands. Aztec rule has been described by scholars as "hegemonic" or "indirect". Rulers of conquered cities were usually left in power as long as they agreed to pay semi-annual tribute to the alliance or provided military support in wars with enemy states.
The word "Aztec" is a modern invention and would not have been recognized by the people themselves. It has variously been used to refer to the Triple Alliance empire, the Nahuatl-speaking people of central Mexico prior the Spanish conquest, or the Mexica ethnicity specifically. The name comes from a Nahuatl word meaning "people from Aztlan", reflecting the mythical place of origin for Nahua peoples. For the purpose of this article, Aztec refers only to those cities that constituted or were subject to the Triple Alliance. For the broader use of the term, see the article on Aztec civilization.

Before the Empire 
Nahua peoples were not originally indigenous to central Mexico, but are instead descended from Chichimec peoples who migrated into the region from the north in the early 13th century. According to the pictographic codices in which the Aztecs recorded their history, the place of origin was called Aztlán. The early migrants settled the Basin of Mexico and surrounding lands by establishing a series of independent city-states. These early Nahua cities were ruled by petty kings called "tlatoque" (singular "tlatoani"). Most of the cities and towns that had been established in the region prior to the Nahua migration were assimilated into Nahua culture.
These early city-states fought various small-scale wars with each other, but due to the shifting nature of alliances no individual city gained dominance. The Mexica were the last of the Aztlan migrants to arrive in Central Mexico. They entered the Basin of Mexico around the year 1250 AD, by which time most of the good agricultural land had already been claimed. The Mexica persuaded the king of Culhuacan to allow them to settle in a relatively infertile patch of land called Chapultepec or Grasshopper hill. The Mexica became hired mercenaries for Culhuacan.
After serving the king of Culhuacan in battle, the Mexica were granted one of his daughters to rule over them. According to mythological native accounts, the Mexica sacrificed her by flaying her skin. According to native Aztec history, this was done on the command of their god Huitzilopochtli. When the king of Culhuacan learned of this, he attacked and used his army to drive the Mexica from Tizaapan by force. The Mexica then moved to an island in the middle of Lake Texcoco, where an eagle nested on a nopal cactus. The Mexica interpreted this as a sign from their god and founded their new city, Tenochtitlan, on this island in the year 2 House (1325 AD).
The new Mexica city allied itself with the city of Azcapotzalco and paid tribute to its king, Tezozomoc. With Mexica assistance, Azcopotzalco began to expand into a small tributary empire. Until this point, the Mexica ruler was not recognized as a legitimate king. Mexica leaders successfully petitioned one of the kings of Culhuacan to provide a daughter to marry into the Mexica line. Their son, Acamapichtli, was enthroned as the first tlatoani of Tenochtitlan in the year 1372.
As the Tepanecs of Azcapotzalco continued to expand their kingdom with the assistance of the Mexica, the Acolhua city of Texcoco grew in power in the eastern portion of the lake basin. War eventually erupted between the two states, and the Mexica played a vital role in the conquest of Texcoco. By this time, Tenochtitlan had grown into a major city and was rewarded for its loyalty to the Tepanecs by receiving Texcoco as a tributary province.
The Tepanec War and the Triple Alliance 
In 1426, the Tepanec king Tezozomoc died, and the resulting succession crisis precipitated a civil war. The Mexica supported Tezozomoc's preferred heir Tayahauh who was initially enthroned as king. His brother, Maxtla, soon usurped the throne and turned against those factions that opposed him, including the Mexica king Chimalpopoca. Chimalpopoca died shortly after this, possibly assassinated by Maxtla.
The new Mexica king Itzcoatl remained defiant to Maxtla, and in response Maxtla had Tenochtitlan blockaded and demanded increased tribute payments. Maxtla similarly turned against the Acolhua, and the king of Texcoco, Nezahualcoyotl fled into exile. Nezahualcoyotl recruited the military assistance of the king of Huexotzinco, and the Mexica gained the support of a dissident Tepanec city, Tlacopan. In 1427, Tenochtitlan, Texcoco, Tlacopan, and Huexotzinco went to war with Azcapotzalco and emerged victorious in 1428.
After the war, Huexotzinco withdrew and the three remaining cities formed a treaty known today as the Triple Alliance. The Tepanec lands were carved up between the three cities who agreed to cooperate in future wars of conquest. Land acquired from these conquests was to be held by the three cities together. Tribute was to be divided so that two fifths each went to Tenochtitlan and Texcoco and one fifth went to Tlacopan. Each of the three kings of the alliance in turn assumed the title "huetlatoani" ("Elder Speaker", often translated as "Emperor"), which placed them in a de jure position above the rulers of other city-states ("tlatoani").
The Triple Alliance of Tenochtitlan, Texcoco, and Tlacopan would, in the next 100 years, come to dominate the Valley of Mexico and extend its power to both the Gulf of Mexico and the Pacific shore. Over this period, Tenochtitlan gradually became the dominant power in the alliance. Two of the primary architects of this alliance were the half-brothers Tlacaelel and Motecuzoma, nephews of Itzcoatl. Motecuzoma would eventually succeed Itzcoatl as the Mexica huetlatoani in 1440. Tlacaelel occupied the newly created title of "Cihuacoatl", roughly equivalent to "Prime Minister".
Imperial Reforms 
Shortly after the formation of the Triple Alliance, Itzcoatl and Tlacaelel instigated sweeping reforms on the Aztec state and religion. Tlacaelel ordered the burning of most of the extant Aztec books, claiming that they contained lies and that it was "not wise that all the people should know the paintings". He thereafter rewrote the history of the Aztec people, placing the Mexica in a more central role.
After Motecuzoma I succeeded Itzcoatl as the Mexica emperor, more reforms were instigated to maintain control over conquered cities. Uncooperative kings were replaced with puppet rulers loyal to the Mexica. A new imperial tribute system established Mexica tribute collectors that taxed the population directly, bypassing the authority of local dynasties. Nezahualcoyotl also instituted a policy in the Acolhua lands of granting subject kings tributary holdings in lands far from their capitals. This was done to create an incentive for cooperation with the empire; if a city's king rebelled, he lost the tribute he received from foreign land. Some rebellious kings were replaced by "calpixque", or appointed governors rather than dynastic rulers.
Motecuzoma issued new laws that further separated nobles from commoners and instituted the death penalty for adultery and other offenses. By royal decree, a religiously-supervised school was built in every neighborhood. Commoner neighborhoods had a school called a "telpochcalli" where they received basic religious instruction and military training. A second, more prestigious type of school called a "calmecac" served to teach the nobility, as well as commoners of high standing seeking to become priests or artisans. Motecuzoma also created a new title called "quauhpilli" that could be conferred on commoners. This title was a form of non-hereditary lesser nobility awarded for outstanding military or civil service (similar to the English knight). In some rare cases, commoners that received this title married into royal families and became kings.
One component of this reform was the creation of ritual wars called the Flower Wars. These wars created a steady supply of experienced Aztec warriors and war captives for human sacrifice. Flower wars were pre-arranged by the emperors and enemy cities and conducted specifically for the purpose of collecting prisoners for sacrifice. According to native historical accounts, these wars were instigated by Tlacaelel as a means of appeasing the gods in response to a massive drought that gripped the Basin of Mexico from 1450-4. The flower wars were mostly waged between the Aztec Empire and the neighboring cities of Tlaxcala.
Early Years of Expansion 
After the defeat of the Tepanecs, Itzcoatl and Nezahualcoyotl rapidly consolidated power in the Basin of Mexico and began to expand beyond its borders. The first targets for imperial expansion were Coyoacan in the Basin of Mexico and Cuauhnahuac and Huaxtepec in the modern Mexican state of Morelos. These conquests provided the new empire with a large influx of tribute, especially agricultural goods.
On the death of Itzcoatl, Motecuzoma I was enthroned as the new Mexica emperor. The expansion of the empire was briefly halted by a major four-year drought that hit the Basin of Mexico in 1450, and several cities in Morelos had to be re-conquered after the drought subsided. Motecuzoma and Nezahualcoyotl continued to expand the empire east towards the Gulf of Mexico and south into Oaxaca. In 1468, Motecuzoma I died and was succeeded by his son, Axayacatl. Most of Axayacatl's thirteen-year-reign was spent consolidating the territory acquired under his predecessor. Motecuzoma and Nezahualcoyotl had expanded rapidly and many provinces rebelled.
At the same time as the Aztec Empire was expanding and consolidating power, the Tarascan Empire in West Mexico was similarly expanding. In 1455, the Tarascans under their king Tzitzipandaquare had invaded the Toluca Valley, claiming lands previously conquered by Motecuzoma and Itzcoatl. In 1472, Axayacatl re-conquered the region and successfully defended it from Tarascan attempts to take it back. In 1479, Axayacatl launched a major invasion of the Tarascan Empire with 32,000 Aztec soldiers. The Tarascans met them just across the border with 50,000 soldiers and scored a resounding victory, killing or capturing over 90% of the Aztec army. Axayacatl himself was wounded in the battle, retreated to Tenochtitlan, and never engaged the Tarascans in battle again.
In 1472, Nezahualcoyotl died and his son Nezahualpilli was enthroned as the new huetlatoani of Texcoco. This was followed by the death of Axayacatl in 1481. Axayacatl was replaced by his brother Tizoc. Tizoc's reign was notoriously brief. He proved to be ineffectual and did not significantly expand the empire. Apparently due to his incompetence, Tizoc was likely assassinated by his own nobles five years into his rule.
Later Years of Expansion 
Tizoc was succeeded by his brother Ahuitzotl in 1486. Like his predecessors before him, the first part of Ahuitzotl's reign was spent suppressing rebellions which were commonplace due to the indirect nature of Aztec rule. Ahuitzotl then began a new wave of conquests including the Valley of Oaxaca and the Soconusco Coast. Due to increased border skirmishes with the Tarascans, Ahuitzotl conquered the border city of Otzoma and turned the city into a military outpost. The population of Otzoma was either killed or dispersed in the process. The Tarascans subsequently established fortresses nearby to protect against Aztec expansion. Ahuitzotl responded by expanding further west to the Pacific Coast of Guerrero.
By the reign of Ahuitzotl, the Mexica were the largest and most powerful faction in the Aztec Triple Alliance. Building on the prestige the Mexica had acquired over the course of the conquests, Ahuitzotl began to use the title "huehuetlatoani" ("Eldest Speaker") to distinguish himself from the rulers of Texcoco and Tlacopan. Even though the alliance still technically ran the empire, the Mexica Emperor now assumed nominal if not actual seniority.
Ahuitzotl was succeeded by his brother Motecuzoma II in 1502. Motecuzoma II spent most of his reign consolidating power in lands conquered by his predecessors. In 1515, Aztec armies commanded by the Tlaxcalan general Tlahuicole invaded the Tarascan Empire once again. The Aztec army failed to take any territory and was mostly restricted to raiding. The Tarascans defeated them and the army withdrew.
Motecuzoma II instituted more imperial reforms. After the death of Nezahualcoyotl, the Mexica Emperors had become the de facto rulers of the alliance. Motecuzoma II used his reign to attempt to consolidate power more closely with the Mexica Emperor. He removed many of Ahuitzotl's advisors and had several of them executed. He also abolished the "quauhpilli" class, destroying the chance for commoners to advance to the nobility. His reform efforts were inevitably cut short by the Spanish Conquest in 1519.
Spanish Conquest 
Conquistador Hernán Cortés landed in the Yucatán in 1519 with 100 sailors and 530 soldiers (most armed with only a sword and shield). Cortés had actually been removed as the expedition's commander by the governor of Cuba, Diego Velásquez, but had stolen the boats and left without permission. At the island of Cozumel, Cortés encountered a shipwrecked Spaniard named Gerónimo de Aguilar who joined the expedition and translated between Spanish and Mayan. The expedition then sailed west to Campeche, where after a brief battle with the local army, Cortés was able to negotiate peace through his interpreter, Aguilar. The King of Campeche gave Cortés a second translator, a slave woman named Malintzin. Aguilar translated from Spanish to Mayan and Malintzin translated from Mayan to Nahuatl.
Cortés then sailed from Campeche to Cempoala, a tributary province of the Aztec Triple Alliance. Nearby, he founded the town of Veracruz where he met with ambassadors from the reigning Mexica emperor, Motecuzoma II. When the ambassadors returned to Tenochtitlan, Cortés went to Cempoala to meet with the local Totonac leaders. After the Totonac ruler told Cortés of his various grievances against the Mexica, Cortés convinced the Totonacs to imprison an imperial tribute collector. Cortés subsequently released the tribute collector after persuading him that the move was entirely the Totonac's idea and that he had no knowledge of it. Having effectively declared war on the Aztecs, the Totonacs provided Cortés with 20 companies of soldiers for his march to Tlaxcala. At this time several of Cortés's soldiers attempted to mutiny. When Cortés discovered the plot, he had his ships scuttled and sank them in the harbor to remove any possibility of escaping to Cuba.
The Spanish-led Totonac army crossed into Tlaxcala to seek the latter's alliance against the Aztecs. However, the Tlaxcalan general Xicotencatl the Younger believed them to be hostile, and attacked. After fighting several close battles, Cortés eventually convinced the leaders of Tlaxcala to order their general to stand down. Cortés then secured an alliance with the people of Tlaxcala, and traveled from there to the Basin of Mexico with a smaller company of 5,000-6,000 Tlaxcalans and 400 Totonacs, in addition to the Spanish soldiers. During his stay in the city of Cholula, Cortés claims he received word of a planned ambush against the Spanish. In a pre-emptive response, Cortés directed his troops attack and kill a large number of unarmed Cholulans gathered in the main square of the city.
Following the massacre at Cholula, Hernan Cortés and the other Spaniards entered Tenochtitlan, where they were greeted as guests and given quarters in the palace of former emperor Axayacatl. After staying in the city for six weeks, two Spaniards from the group left behind in Veracruz were killed in an altercation with an Aztec lord named Quetzalpopoca. Cortés claims that he used this incident as an excuse to take Motecuzoma prisoner under threat of force. For several months, Motecuzoma continued to run the kingdom as a prisoner of Hernan Cortés. Then, in 1520, a second, larger Spanish expedition arrived under the command of Pánfilo de Narváez sent by Diego Velásquez with the goal of arresting Cortés for treason. Before confronting Narváez, Cortés secretly persuaded Narváez's lieutenants to betray him and join Cortés.
While Cortés was away from Tenochtitlan dealing with Narvaez, his lieutenant Pedro de Alvarado massacred a group of Aztec nobility in response to a ritual of human sacrifice honoring Huitzilopochtli. The Aztecs retaliated by attacking the palace where the Spanish were quartered. Cortés returned to Tenochtitlan and fought his way to the palace. He then took Motecuzoma up to the roof of the palace to ask his subjects to stand down. However, by this point the ruling council of Tenochtitlan had voted to depose Motecuzoma and had elected his brother Cuitlahuac as the new emperor. One of the Aztec soldiers struck Motecuzoma in the head with a sling stone, and he died several days later – although the exact details of his death are unclear.
During the battle of La Noche Triste, the Spaniards and their Indian allies fought their way out of the city and retreated to Tlaxcala, taking heavy casualties. After this incident, a smallpox outbreak hit Tenochtitlan. As the American Indians had no previous exposure to smallpox, this outbreak alone killed more than 50% of the region's population, including the emperor, Cuitlahuac. While the new emperor Cuauhtémoc dealt with the smallpox outbreak, Cortés raised an army of Tlaxcalans, Totonacs, and others discontent with Aztec rule. With a combined army of up to 100,000 soldiers, the overwhelming majority of which were Indian rather than Spanish, Cortés marched back into the Basin of Mexico. Through numerous subsequent battles and skirmishes, he captured the various towns and cities around the lake shore and surrounding mountains, including the other capitals of the Triple Alliance, Tlacopan and Texcoco.
Using boats constructed in Texcoco from parts salvaged from the scuttled ships, Cortés blockaded and laid siege to Tenochtitlan for a period of several months. Eventually, the Spanish-led army assaulted the city both by boat and using the elevated causeways connecting it to the mainland. Although the attackers took heavy casualties, and the city of Tenochtitlan was thoroughly destroyed in the process, the Aztecs were ultimately defeated. Cuauhtémoc was captured as he attempted to flee the city. Cortés kept him prisoner and tortured him for a period of several years before finally executing him in 1525.
The Aztec Empire was an example of an empire that ruled by indirect means. Like most European empires, it was ethnically very diverse, but unlike most European empires, it was more of a system of tribute than a single unitary of government. In the theoretical framework of imperial systems posited by Alexander J. Motyl the Aztec empire was an informal or hegemonic empire because it did not exert supreme authority over the conquered lands, it merely expected tributes to be paid. It was also a discontinuous empire because not all dominated territories were connected, for example the southern peripheral zones of Xoconochco were not in direct contact with the center. The hegemonic nature of the Aztec empire can be seen in the fact that generally local rulers were restored to their positions once their city-state was conquered and the Aztecs did not interfere in local affairs as long as the tribute payments were made.
Although the form of government is often referred to as an empire, in fact most areas within the empire were organized as city-states (known as an altepetl in Nahuatl, the language of the Aztecs). These were small polities ruled by a king (singular tlatoque, plural tlatoani) from a dynasty. The Early Aztec period was a time of growth and competition among altepeme. Even after the empire was formed (1428) and began its program of expansion through conquest, the altepetl remained the dominant form of organization at the local level. The efficient role of the altepetl as a regional political unit was largely responsible for the success of the empire's hegemonic form of control.
It should be remembered that the term "Aztec empire" is a modern one, not one used by the Aztec themselves. The empire itself was at its core composed of three Nahuatl-speaking city states. Over time, asymmetries of power elevated one of those city states, Tenochtitlan, above the other two. The "Triple Alliance" came to establish hegemony over much of central Mesoamerica, including areas of linguistic and cultural diversity. Administration of the empire was performed through largely traditional, indirect means. However, over time something of a nascent bureaucracy arguably began to form as the state increasingly centralized.
Central Administration 
Before the reign of Netzahualcoyotl, the Aztec empire was a confederation along traditional Mesoamerican lines. Independent altepetl were led by tlatoani (lit., "speakers"), who supervised village headmen, who in turn supervised groups of households. A typical Mesoamerican confederation placed a Huey Tlatoani (lit., "great speaker") at the head of several tlatoani. Following Nezahualcoyotl, the Aztec empire followed a somewhat divergent path, with some tlatoani of recently conquered or otherwise subordinated altepetl becoming replaced with calpixque stewards charged with collecting tribute on behalf of the Huetlatoani rather than simply replacing an old tlatoque with new ones from the same set of local nobility.
Yet the Huey tlatoani was not the sole executive. It was the responsibility of the Huey tlatoani to deal with the external issues of empire; the management of tribute, war, diplomacy, and expansion were all under the purview of the Huey tlatoani. It was the role of the Cihuacoatl to govern the city of Tenochtitlan itself. The Cihuacoatl was always a close relative of the Huey tlatoani; Tlacaelel, for example, was the brother of Moctezuma I. Both the title "Cihuacoatl", which means "female snake" (it is the name of a Nahua deity), and the role of the position, somewhat analogous to a European Viceroy or Prime Minister, reflect the dualistic nature of Nahua cosmology. Neither the position of Cihuacoatl nor the position of Huetlatoani were priestly, yet both did have important ritual tasks. Those of the former were associated with the 'female' wet season, those of the latter with the 'male' dry season. While the position of Cihuacoatl is best attested in Tenochtitlan, it is known that the position also existed the nearby altepetl of Atzcapotzalco, Culhuacan, and Tenochtitlan's ally Texcoco. Despite the apparent lesser status of the position, a Cihuacoatl could prove both influential and powerful, as in the case of Tlacaelel.
Somewhat early on in the history of the empire, Tenochtitlan developed a four-member military and advisory Council who assisted the Huey tlatoani in his decision making: the tlacochcalcatl; the tlaccatecatl; the ezhuahuacatl; and the tlillancalqui. This design not only provided advise for the ruler, it also served to contain ambition on the part of the nobility, as henceforth Huey Tlatoani could only be selected from the Council. Moreover, the actions of any one member of the Council could easily be blocked by the other three, providing a simple system of checks on the ambition higher officials. These four Council members were also generals, members of various military societies. The ranks of the members were not equal, with the tlacochcalcatl and tlaccatecatl having a higher status than the others. These two Councillors were members of the two most prestigious military societies, the cuauhchique ("shorn ones") and the otontin ("Otomies").
Provincial Administration 
Traditionally, provinces and altepetl were governed by hereditary tlatoani. As the empire grew, the system evolved further and some tlatoani were replaced by other officials. As has already been mentioned, directly-appointed stewards (singular calpixqui, plural calpixque) were sometimes imposed on altepetl instead of the selection of provincial nobility to the same position of tlatoani. At the height of empire, the organization of the state into tributary and strategic provinces saw an elaboration of this system. The 38 tributary provinces fell under the supervision of high stewards, or huecalpixque, whose authority extended over the lower-ranking calpixque. These calpixque and huecalpixque were essentially managers of the provincial tribute system which was overseen and coordinated in the paramount capital of Tenochtitlan not by the huetlatoani, but rather by a separate position altogether: the petlacalcatl. On the occasion that a recently-conquered altepetl was seen as particularly restive, a military governor, or cuauhtlatoani, was placed at the head of provincial supervision. During the reign of Moctezuma I, the calpixque system was elaborated, with two calpixque assigned per tributary province. One was stationed in the province itself, perhaps for supervising the collection of tribute, and the other in Tenochtitlan, perhaps for supervising storage of tribute. Tribute was drawn from commoners, the macehualtin, and distributed to the nobility, be they 'kings' (tlatoque), lesser rulers (teteuctin), or provincial nobility (pipiltin).
Tribute collection was supervised by the above officials and relied upon the coercive power of the Aztec military, but also upon the cooperation of the pipiltin (the local nobility who were themselves exempt from and recipient to tribute) and the hereditary class of merchants known as pochteca. These pochteca had various gradations of ranks which granted them certain trading rights and so were not necessarily pipiltin themselves, yet they played an important role in both the growth and administration of the Aztec tributary system nonetheless. The power, political and economic, of the pochteca was strongly tied to the political and military power of the Aztec nobility and state. In addition to serving as diplomats (teucnenenque, or "travelers of the lord") and spies in the prelude to conquest, higher-ranking pochteca also served as judges in market plazas and were to certain degree autonomous corporate groups, having administrative duties within their own estate.

Provincial Structure 
Originally, the Aztec empire was loose alliance between three cities: Tenochtitlan, Texcoco, and the most junior partner, Tlacopan. As such, they were known as the 'Triple Alliance.' This political form was very common in Mesoamerica, where alliances of city-states were ever fluctuating. However, overtime it was Tenochtitlan which assumed paramount authority in the alliance, and although each partner city shared spoils of war and rights to regular tribute from the provinces and were governed by their own Huetlatoani, it was Tenochtitlan which became the largest, most powerful, and most influential of the three cities. It was the de facto and acknowledged center of empire.
Though they were not described by the Aztec this way, there were essentially two types of provinces: Tributary and Strategic. Strategic provinces were essentially subordinate client states which provided tribute or aid to the Aztec state under "mutual consent". Tributary provinces, on the other hand, provided regular tribute to the empire; obligations on the part of Tributary provinces were mandatory rather than consensual.

Ideology and State 
Rulers, be they local teteuctin or tlatoani, or central Huetlatoani, were seen as representatives of the gods and therefore ruled by divine right. Tlatocayotl, or the principle of rulership, established that this divine right was inherited by descent. Political order was therefore also a cosmic order, and to kill a tlatoani was to transgress that order. For that reason, whenever a tlatoani was killed or otherwise removed from their station, a relative and member of the same bloodline was typically placed in their stead. The establishment of the office of Huetlatoani understood through the creation of another level of rulership, hueitlatocayotl, standing in superior contrast to the lesser tlatocayotl principle.
Expansion of the empire was guided by a militaristic interpretation of Nahua religion, specifically a devout veneration of the sun god, Huitzilopochtli. Militaristic state rituals were performed throughout the year according to a ceremonial calendar of events, rites, and mock battles. The time period they lived in was understood as the Ollintonatiuh, or Sun of Movement, which was believed to be the final age after which humanity would be destroyed. It was under Tlacaelel that Huitzilopochtli assumed his elevated role in the state pantheon and who argued that it was through blood sacrifice that the Sun would be maintained and thereby stave off the end of the world. It was under this new, militaristic interpretation of Huitzilopochtli that Aztec soldiers were encouraged to fight wars and capture enemy soldiers for sacrifice. Though blood sacrifice was common in Mesoamerica, the scale of human sacrifice under the Aztecs was likely unprecedented in the region.
A code of law seems to have been established under the reign of Moctezuma I. These laws served to establish and govern relations between the state, classes, and individuals. Punishment was to be meted out solely by state authorities. Nahua mores were enshrined in these laws, criminalizing public acts of homosexuality, drunkenness, and nudity, not to mention more universal proscriptions against theft, murder, and property damage. As stated before, pochteca could serve as judges, often exercising judicial oversight of their own members. Likewise, military courts dealt with both cases within the military and without during wartime. There was an appeal process, with appellate courts standing between local, typically market-place courts, on the provincial level and a supreme court and two special higher appellate courts at Tenochtitlan. One of those two special courts dealt with cases arising within Tenochtitlan, the other with cases originating from outside the capital. The ultimate judicial authority laid in hands of the Huetlatoani, who had the right to appoint lesser judges.
