When Did the Aztec Empire Start and End: A Brief Timeline of Mesoamerica’s Last Great Civilization

The Aztec Empire emerged in 1428 through the Triple Alliance of three city-states and ended in 1521 due to the Spanish conquest, marking Mesoamerica's final native civilization.

The Aztec Empire was a powerful civilization that left a lasting mark on history.

It started in 1428 when three city-states joined forces.

These were Mexico-Tenochtitlan, Tetzcoco, and Tlacopan.

Together, they formed the Triple Alliance that ruled much of central Mexico.

The Aztec Empire lasted for 93 years, coming to an end in 1521 when Spanish conquistadors led by Hernán Cortés overthrew it. This event marked the fall of Mesoamerica’s last great native civilization.

The Spanish invasion brought about huge changes in the region.

During its time, the Aztec Empire grew to control a large area.

At its peak, it covered most of northern Mesoamerica.

The Aztecs were skilled in farming and trade.

They built grand cities and made big advances in art and science.

Their capital, Tenochtitlan, was one of the largest cities in the world at that time.

Origins of the Aztecs

The Aztecs have a rich history that began long before they became a powerful empire.

Their journey from a mythical homeland to founding a great city is a tale of migration and determination.

Mythical Homeland Aztlan

The Aztecs, also known as the Mexica, believed they came from a place called Aztlan.

This mythical homeland was said to be an island in a lake.

The exact location of Aztlan is unknown.

Some think it might have been in northwest Mexico.

Others say it could be just a legend.

In Aztlan, the Aztecs were part of a larger group called the Nahuatl-speaking peoples.

They shared a common language and culture.

Migration to the Valley of Mexico

Around the 12th century, the Aztecs left Aztlan.

They began a long journey southward.

This trip took many years.

The Aztecs were part of the Chichimec peoples, who were seen as less civilized by other groups.

As they traveled, they learned from the cultures they met.

They moved through different areas, sometimes settling for a while before moving on.

The Aztecs faced many challenges during this time.

Foundation of Tenochtitlan

In 1325, the Aztecs finally found their promised land.

They saw an eagle perching on a cactus with a snake in its beak.

This was the sign they had been waiting for.

The place was a small, swampy island in Lake Texcoco.

Here, they founded their capital city, Tenochtitlan.

The Aztecs built Tenochtitlan on this difficult terrain.

They created chinampas, or floating gardens, to grow food.

The city grew quickly and became the heart of the Aztec world.

The Rise of the Aztec Empire

The Aztec Empire grew from humble beginnings to become a powerful force in central Mexico.

It started with an alliance of three city-states and expanded through conquest and clever politics.

Triple Alliance and Expansion

The Aztec Empire began in 1428 when three city-states joined forces.

These were Tenochtitlan, Texcoco, and Tlacopan.

Together, they formed the Triple Alliance.

Tenochtitlan was the strongest partner and grew to be the heart of the empire.

The alliance was smart.

It let them pool their strengths and take on bigger rivals.

They first beat the Tepanec people of Azcapotzalco.

This win gave them control of the Valley of Mexico.

From there, the Aztecs kept growing.

They used both fighting and diplomacy to bring more areas under their rule.

Conquering City-States

The Aztecs were good at taking over other city-states, called altepetl.

They didn’t always destroy these places.

Often, they let local rulers stay in charge if they paid tribute.

This approach helped the empire grow fast.

By 1500, the Aztecs controlled most of central Mexico.

They made other cities pay them with goods like gold, cotton, and food.

The Aztec army was strong and feared.

They used this to scare some cities into joining without a fight.

But they also fought many battles to expand their land.

Political and Social Structures

The Aztec Empire had a complex system of government and social classes.

It mixed strict hierarchies with some opportunities for people to move up in society.

Hierarchy and Nobility

Noble families came next in rank.

They held important jobs in the government and military.

Priests also had high status.

They took care of religious duties and ran schools.

The empire was split into provinces.

Each had a governor picked by the emperor.

Local rulers kept some power, as long as they paid taxes to the Aztecs.

Nobles could earn their status through brave deeds in battle.

This gave common people a chance to climb the social ranks if they were skilled warriors.

Commoners and Slavery

Most Aztecs were commoners.

They worked as farmers, craftspeople, or traders.

Commoners lived in family groups called calpulli.

These groups owned land together and shared some duties.

Aztec society allowed slavery, but it wasn’t like slavery in other places.

Slaves could own property and even buy their freedom.

Some people chose to become slaves to pay off debts.

Merchants formed a special class.

They could get rich through trade, but they weren’t allowed to show off their wealth too much.

The Aztecs valued hard work.

Even commoners could earn respect and better jobs if they did well at school or in battle.

Religion and Mythology

Their beliefs shaped their daily lives and society.

These floating gardens were super productive.

They grew maize, beans, squash, and other crops on them.

Farmers dug canals and piled up mud to make new land.

They planted willow trees to hold the soil in place.

This helped him gain allies.

He met the Aztec ruler Montezuma in Tenochtitlan.

At first, things seemed peaceful.

But soon, fighting broke out.

The Spanish took Montezuma hostage.

He died during this time.

The Aztecs were angry and fought back hard.
