Aztec human sacrifice was a key aspect of Aztec religion and culture. For instance, the Aztec believed that human sacrifice was necessary as a way of honoring the many different Aztec gods. Spanish conquistadorsSpanish soldiers and explorers who invaded and conquered civilizations in the Americas during the 1500s. first noted the practise of human sacrifice during the early period of the Spanish conquest of the Aztec Empire. This article explores the history and significance of human sacrifice in the context of the Aztec Empire.
FactsthatCrunchThe Aztec believed the gods had created the world through their own sacrifice, so humans owed the gods a debt of blood that had to be repaid.
In Aztec religion, the survival of the universe depended on keeping the gods strong through offerings of blood. This belief made human sacrifice a central and necessary part of Aztec religious practice, not a separate or unusual act.
Who Were the Aztec?
The Aztec Empire was a civilization in central Mexico that thrived in the time before the arrival of European explorers during the Age of Exploration. Throughout its history as a civilization the Aztec Empire expanded across much of central Mexico and other surrounding areas, to become the most dominant and powerful people in the region. Tenochtitlan, the main Aztec city (or altepetlAn Aztec city-state, used to refer to both the main Aztec city and the conquered city-states within the empire.), was the center of this vast empire.
FactsthatCrunchTenochtitlan was founded by the Aztec on a lake island in the Valley of Mexico in 1325 CE and became the political and ceremonial heart of the Aztec Empire. The city was organized around the Templo Mayor, a great double pyramid dedicated to the gods Huitzilopochtli and Tlaloc, and it stood at the center of a grid of streets, canals, and causeways. At its height, Tenochtitlan was among the largest cities in the world.
Today, Mexico City stands directly on top of the old Aztec capital, built over the filled-in bed of Lake Texcoco after the Spanish conquest of 1521. The ruins of the Templo Mayor were uncovered in downtown Mexico City in 1978 and are now an active archaeological site open to the public. The Templo Mayor Museum next to the ruins holds thousands of artifacts recovered from the site.
Mexico City sits directly on the remains of Tenochtitlan, making its streets and foundations a record of Aztec civilization that archaeologists continue to study today.
Aztec Human Sacrifice – Spanish Account
An important aspect of Aztec religion and culture was the practice of human sacrifice. Human sacrifice had a long history in MesoamericaThe historical region covering central Mexico and parts of Central America where many ancient civilizations developed., before the rise to prominence of the Aztec Empire. For example, there is archaeological evidence that both the Toltec and Teotihuacan practiced human sacrifice in the centuries before the Aztec Empire. As such, historians consider human sacrifice to be a relatively common practice in Mesoamerica during years before and during the Aztec Empire. However, to the Spanish conquistadors that arrived in the Aztec territory in the early 1520s, the practice of human sacrifice carried out by the Aztecs was horrific and brutal. For example, several early accounts by these Spanish conquistadors highlight their horror at seeing festivals and ceremonies in which people were sacrificed atop Aztec temples and pyramids. In Tenochtitlan, the Aztec capital, sacrifices were carried out on top of the Templo Mayor (Great Pyramid of Tenochtitlan).
For example, a first hand account of the Aztec sacrifice comes from Spanish conquistador Bernal Diaz del Castillo’s famous memoir. He was a conquistador in the time of the Age of Exploration and accompanied Hernán Cortés on his famous mission to overthrow the Aztec Empire in 1521. In his memoir, Bernal Diaz del Castillo stated: “Hardly a day passed by that these people did not sacrifice from three to four, and even five Indians, tearing the hearts out of their bodies, to present them to the idols and smear blood on the walls of the temple. The arms and legs of these unfortunate beings were then cut off and devoured, just in the same way we should fetch meat from a butcher’s shop and eat it: indeed I even believe that human flesh is exposed for sale cut up in their markets.”

Human Sacrifice in Mesoamerica Before the Aztec EmpireAztec Human Sacrifice – Aztec Religious Tradition
However, from the perspective of the Aztec, sacrifice was necessary to ensure the survival of life. For instance, in Aztec religion, the world was created from the sacrifice of the gods. As such, they viewed sacrifice as necessary to repay their debts to the gods. Therefore, sacrifice did not necessarily just focus on human beings, as both animals and precious objects were also offered to the gods. Further to this idea, some historians have suggested that the Aztec practice of sacrifice was designed to protect and ensure the survival of the universe. This concept is best related to the Aztec god Huitzilopochtli, who was one of the main gods of the Aztec and likely the most prominent.
In Aztec tradition Huitzilopochtli was viewed as the sun, his sister the moon, and his brothers the stars. The constant movement of the sun, moon and stars was viewed by the Aztecs as an ongoing battle between Huitzilopochtli and his siblings. Thus, the Aztec believed that they needed to provide tributePayments or offerings that conquered peoples were forced to give to the Aztec Empire as a sign of submission. to Huitzilopochtli in order to ensure the sun’s survival and ability to ‘fight’ each day. This tribute was usually in the form of human sacrifice, which was a central component of Aztec religious practices. This is because human blood was viewed as necessary for the survival of the gods. Tribute for Huitzilopochtli generally occurred on a festival called Panquetzaliztli which was held in the 15th month of the Aztec calendar. In general, warriors or slaves were sacrificed to honor Huitzilopochtli. Therefore, to the Aztec people sacrifice was an important and necessary aspect of life to ensure the survival of the world and universe. There were regular festivals and sacrifices to other Aztec gods throughout the timeline of the Aztec calendar.
FactsthatCrunchThe Aztec god Huitzilopochtli was identified with the sun, and that belief drove the Aztec to carry out human sacrifice as a regular duty to keep the sun alive and moving across the sky.
Aztec Human Sacrifice – Summary and Significance
The Aztec obtained the people for sacrifice in a number of different ways. Some were willingly sacrificed while others were prisoners in war. Regardless, the Aztec (and other Mesoamerican societies) viewed dying for the gods to be an honor. Following the Aztec’s founding and construction of Tenochtitlan in the Valley of Mexico in 1325, they quickly established their authority across the other societies in the valley. At the time the Valley of Mexico was populated by many different powerful civilizations, including: Chalco, Tepanec, Tlacopan, Texcoco, Culhuacan, and Chichimec. Several of these civilizations were also on the shores of Lake Texcoco, including the Culhuacan which were on the south shore. The Aztec controlled many of these different societies by forcing them to provide tributes for payment and ritual sacrifice. For example, conquered city-states, which are referred to as ‘altepetl’, were allowed to maintain their current rulers and religion so long as they met several requirements, including: support the Aztec Empire and tlatoani of Tenochtitlan, pay tribute to Tenochtitlan, and include the Aztec god Huitzilopochtli in their own religious beliefs and practices. As such, the conquered Mesoamerican city-states likely supplied the Aztec with slaves to be used in sacrifice.
This was one way in which the Aztec received people for their ritual sacrifice. Another way was from ritualized wars that the Aztec and other Mesoamerican societies participated in called Flower Wars. These battles occurred at different times of the year than the campaigns of conquest that the Aztec used to expand their empire and were much different in their intent. For example, the Flower WarsOrganized ritual battles between the Aztec and rival city-states fought primarily to capture prisoners for sacrifice. were generally organized battles in which members of the Triple Alliance including Aztecs faced off against rival city-states. The two sides would structure the battle such that each side had an equal number of warriors and used only close-combat weapons. The purpose of the Flower Wars was for warriors to practice and display their combat skills while also allowing them the ability to take prisoners for the purpose of sacrifice. A common participant of the Flower Wars was the Tlaxcala, who were a rival city-state to the Aztec. Historians believe the Flower Wars occurred primarily between 1450 and 1520 when Spanish conquistadors arrived into the region and famously overthrew the city of Tenochtitlan.
As stated previously, the actual sacrifice generally took place on top of large temples or pyramids with the most prominent being the Templo Mayor in Tenochtitlan. It most commonly involved the removal of the heart of the sacrificed victim. There was even an ornate structure built to hold the removed hearts during the ceremony. Once having their heart removed the body was thrown down the steps of the pyramid to the crowd below. With that said, the removal of the heart was not the only method of death in ritual sacrifice. Depending on the god being celebrated and the festival requirements, ritual sacrifice could also include: death by fire, death by starvation, death by flayingA method of sacrifice that involved the removal of a victim’s skin. (removal of the skin), death in ritual battle, and death by decapitation (removal of the head). As well, who was sacrificed changed with each festival. Sometimes it involved adult slaves, other times children, or people of noble birth. As stated above, death by sacrifice was considered to be an honor as your death would be in tribute to the gods and maintain the survival of the universe. For example, during the festival of Panquetzaliztli, of which Huitzilopochtli was the patron, sacrificial victims were dressed in the manner of Huitzilopochtli’s costume and blue body paint, before their hearts would be sacrificially removed. Those being sacrificed were treated as gods until their death. A final important concept related to ritual sacrifice is the idea of ‘bloodlettingThe practice of deliberately cutting oneself to bleed as a religious offering to the gods.’. Some historians have suggested that bloodletting, causing yourself to bleed, was practiced throughout Mesoamerica and the Aztec Empire. The idea is that Aztec people purposefully caused themselves to bleed by puncturing their tongues or skin with sharp blades as a form of offering to the gods.
FactsthatCrunchThe Aztec and their rivals fought planned battles called Flower Wars, in which both sides agreed to bring the same number of warriors and use only close-combat weapons.
Unlike wars of conquest, these battles were held to let warriors show their skill and take prisoners. Historians believe Flower Wars took place mainly between 1450 and 1520, often against the rival city-state of Tlaxcala.
