In this Grade 7 lesson from California myWorld Interactive, students explore how the Aztec empire rose to power in central Mexico, examining the geographic advantages of the Valley of Mexico and the island capital Tenochtitlan. Students learn key engineering concepts including chinampas, dikes, and aqueducts, and how these innovations supported a growing population. The lesson also covers the structure of Aztec imperial rule, including the Triple Alliance and the tribute system used to govern conquered city-states.
Section 1
Aztecs Engineer a Lake Capital
The Aztecs settled on an island in Lake Texcoco, a location that offered natural protection from enemies. This unique geography shaped how their civilization developed and grew.
To feed a large population in a swampy environment, the Aztecs created chinampas. These were artificial islands built from mud and reeds that served as highly productive floating gardens, allowing for year-round farming.
Section 2
Aztecs Forge an Empire of Tribute
The Aztecs built their empire by joining with two other powerful city-states. This partnership was called the Triple Alliance. Together, they used their combined military strength to conquer neighboring lands in the Valley of Mexico.
An all-powerful emperor, chosen by a council of nobles, ruled the empire. This absolute monarch had the final say in all matters of law, war, and religion.
Section 3
Aztecs Structured a Rigid Society
Aztec society was organized into a strict social hierarchy. At the very top was the emperor, who held absolute power. Below him were nobles and priests, who helped run the government and religious ceremonies.
The largest group was the commoners, which included farmers, artisans, and merchants. At the bottom were slaves. Unlike in other societies, Aztec slaves could own property and buy their freedom, and their children were born free.
Section 4
Religion Drives Aztec Warfare and Sacrifice
Religion was the center of Aztec life. The Aztecs believed their most important god, Huitzilopochtli, was the god of both the sun and war. They thought he battled darkness every night and needed human energy to rise again each morning.
To provide this energy, the Aztecs practiced human sacrifice. They believed offering human hearts and blood was the most sacred gift to keep their god strong and prevent the world from ending. This belief meant that warfare was necessary to capture enemies for these religious ceremonies.
