The Aztec Empire was one of the most powerful and influential civilizations in Mesoamerica
before the arrival of the Spanish. It developed in central Mexico during the 14th–16th centuries
and became known for its impressive cities, military strength, and rich cultural traditions.
Although the empire grew quickly, it also ended abruptly when Spanish forces conquered it in
1521.
1. Origins and Rise of the Aztecs
The Aztecs, also called the Mexica, originally migrated into the Valley of Mexico as a small,
wandering group. According to legend, their god Huitzilopochtli instructed them to settle where
they saw an eagle perched on a cactus with a snake in its beak. They claimed to have seen this
sign on an island in Lake Texcoco, where they founded Tenochtitlán in 1325.
Over time, they formed the Triple Alliance with two neighboring cities—Texcoco and
Tlacopan. This alliance became the foundation of the Aztec Empire, helping them expand
through warfare, tribute collection, and strategic marriages.
2. Tenochtitlán: The Heart of the Empire
Tenochtitlán grew into one of the largest cities in the world at the time, with an estimated
population between 200,000 and 300,000. The city was built on a series of islands connected
by causeways, bridges, and canals.
Key features included:
● The Great Temple (Templo Mayor), dedicated to two major gods
● Markets, especially the huge market at Tlatelolco
● Chinampas, or “floating gardens,” used to grow crops on lake beds
● Palaces and administrative buildings
