Long ago, a great city was built. 

Tenochtitlan was a massive city in Mexico. 

The city was very large and busy. It had many canals for boats. People used these canals to travel. They also made floating gardens to grow food.
Many people lived in the city. Some say over 200,000 people lived there. The city had big temples and palaces. One famous temple was called Templo Mayor.
Tenochtitlan was a huge city in the Valley of Mexico. 

The city was built using clever ways to manage water. 
The Mexica people founded the city around the year 1325. 
Life in Tenochtitlan was very busy and organized. 
Many grand buildings stood at the heart of the city. 
Tenochtitlan was the massive capital of the Aztec Empire. 

The city used a complex system to manage water and land. The island was surrounded by the shallow, brackish waters of Lake Texcoco. To manage this, the Mexica built large causeways. These were wide roads that connected the island to the mainland. They were wide enough for ten horses to walk abreast. These causeways had bridges that could be pulled away for defense. They also allowed canoes to pass through freely. Inside the city, a network of canals allowed for travel by canoe. 
Water management was vital for daily life and hygiene. The city used two terracotta aqueducts to bring fresh water from springs. Each aqueduct was more than 1 kilometer long. This water was used for cleaning and washing. Most people liked to bathe twice every day. Some people, like Moctezuma, reportedly bathed four times a day. They used the root of the Saponaria americana plant as soap. They also used Agave americana roots to clean their clothes. Some people even used a steam bath similar to a sauna.
The founding of the city is tied to an ancient prophecy. The Mexica people looked for a specific sign from their gods. They sought an eagle with a snake in its beak. This eagle had to be perched on a prickly pear cactus. When they saw this sign, they built their city. While the exact date is unclear, 13 March 1325 is used for celebrations. 
Tenochtitlan was a highly organized and stratified society. The city was divided into four main zones or camps. Each camp contained 20 districts called calpullis. These calpullis were groups of families related by kinship or location. Social classes were very clearly defined. The Pipiltin were the noblemen who lived inside the island. The Macehualtin were commoners who lived outside the island. There were also Pochteca, who were traveling merchants. They could become very wealthy through trade. 
Commerce was a massive part of daily life. Each calpulli had its own marketplace. However, the main marketplace was in Tlatelolco. Hernán Cortés estimated this market was twice the size of Salamanca. He claimed 60,000 people traded there every day. Other estimates suggest 20,000 people on normal days. On feast days, the number reached 40,000 people.
The city's era of dominance ended in the early 16th century. Hernán Cortés arrived in November 1519. The city's population was massive, likely between 200,000 and 400,000 people. This made it one of the largest cities in the world. It was much larger than London at that time.
