  • Use three of the words to guess: what do you think happens in this story?

The story, in three parts

Read each part. Then try the questions from memory, and talk about the last one.

Part 1 — A city on the lake

The people we call the Aztecs called themselves the Mexica. Long ago, they were a poor tribe with no home. They walked from place to place for many years. Their god told them to build their city in one special place: where they saw an eagle on a cactus.

Around the year 1325, they saw the eagle. It was on a small island in the middle of a lake, called Lake Texcoco. Today this place is Mexico City. The Mexica built their city there and called it Tenochtitlan.

It was a difficult place to live, but the Mexica were clever. They built long roads of stone across the water to reach the land. They dug canals for their boats. They made floating gardens on the lake to grow maize (corn) and other food. The city grew bigger and bigger. After two hundred years, it was one of the biggest cities in the world — bigger than London or Paris at that time. In the centre stood a great temple, where the priests prayed to their gods.

Quick check — answer from memory, then reveal:

1. What sign showed the Mexica where to build their city?

2. How did the Mexica grow food on a lake?

1. An eagle on a cactus. Their god told them to build where they saw it. They saw it on an island in Lake Texcoco around 1325.

2. They made floating gardens on the lake and grew maize (corn) and other food on them.

Talk about it:
  • The Mexica took a difficult place and made a great city. Can a hard start sometimes help you in the end? When?

Part 2 — A big empire

At first, the Mexica were not strong. They worked for other, more powerful cities. But in 1428, they joined with two other cities and became strong. Their armies went out to fight, and they began to conquer the lands around them. Soon they ruled hundreds of towns and millions of people. They had a big empire.

But the Mexica did not stay in the towns they conquered. They let the local leaders stay. Instead, they made the towns pay tribute. Every year, each town had to send gifts to Tenochtitlan: cotton, gold, feathers, maize and more. If a town did not pay, the army came back. And the Mexica also took prisoners from war. They brought these prisoners to the great temple for sacrifice.

The Mexica believed the sun needed human blood to rise each morning. The priests said the gods must be fed, or the world would end. So there were many sacrifices. But this made the Mexica strong and weak at the same time. The conquered towns paid tribute because they were afraid, not because they loved their rulers. Many of them hated the Mexica. They were waiting for a chance to fight back.

Quick check — answer from memory, then reveal:

1. How did the Mexica control the towns they conquered?

2. Why did many conquered towns hate the Mexica?

1. They let local leaders stay but made the towns pay tribute (gifts) every year and send prisoners for sacrifice. If a town did not pay, the army came back.

2. They paid tribute because they were afraid, not because they loved the Mexica. They hated the tribute and the sacrifices, and wanted a chance to fight back.

Talk about it:
  • The Mexica empire was big but people obeyed only because of fear. Why is fear a weak way to control people?

Part 3 — The strangers from the sea

In 1519, strange ships came to the coast. On them were a few hundred Spanish soldiers, led by a man called Hernán Cortés. They had horses, metal armour and guns — things the Mexica had never seen. The Mexica leader was the emperor Moctezuma II. People say he saw strange signs and did not know what to do. He did not attack the small group of strangers. Instead, he let them walk towards his city.

This was a big mistake. As Cortés walked inland, the people who hated the Mexica joined him. Soon, tens of thousands of local warriors marched with the Spanish. Cortés came into the city as a guest, but then he took Moctezuma prisoner. When the Mexica fought back, they pushed the Spanish out of the city in one night of fighting. But Moctezuma was dead, and the Spanish came back.

Then came an enemy the Mexica could not fight: a terrible illness called smallpox. The Spanish brought it from across the sea. The Mexica had never had this illness, and it killed huge numbers of them. In 1521, Cortés returned and put the city under siege. For about eighty days, the hungry, sick city held on. Then, on 13 August 1521, it fell. The Spanish broke down the great city and built a new city on its ruins. The Aztec empire was gone — but its language, its food and its people are still part of Mexico today.

Quick check — answer from memory, then reveal:

1. Why could Cortés, with only a few hundred men, beat such a big empire?

2. What illness helped to destroy the Mexica, and where did it come from?

1. Many local people who hated the Mexica joined him — tens of thousands of warriors. Moctezuma also hesitated and did not attack the strangers at first.

2. Smallpox, a terrible illness the Spanish brought from across the sea. The Mexica had never had it, so it killed huge numbers of them.

Talk about it:
  • A few hundred Spanish soldiers did not win alone — illness and angry neighbours helped. Does this change the story of "the conquest" for you?

Grammar: orders and rules — "demand that he do" + must / had to

This is a story of priests and emperors who gave orders. When we report a strong order or rule in English, there is a special pattern. After words like demand, order, insist, we use that + a person + the base verb (the simple form, with no -s and no to).

The pattern:
demand / order / insist + that + someone + base verb
• "The priests demanded that a sacrifice be made." (not "is made")
• "The emperor ordered that every town pay tribute." (not "pays")
The base verb does not change for he/she/it — so no -s. And "to be" is just be.
The easy, everyday way — use must or had to. This means almost the same, and it is what we say most of the time:
• "A sacrifice must be made." = the priests demand it.
• "Every town had to pay tribute." = the emperor ordered it.
So: The priests demanded that the gods be fed = The gods must be fed.

1. Write the base verb

After demand / order / insist that, use the base verb. Watch he/she/it — no -s!

1. The priests demanded that a temple (be) built.

2. The emperor ordered that every town (pay) tribute.

3. The priests insisted that the gods (be) fed.

4. Tradition demanded that the city (stand) on the lake.

1. be (base form of "to be", not "is")

2. pay (no -s, even though "town" is he/she/it)

3. be ("be fed", not "is/are fed")

4. stand (base form, no -s)

2. Say it the easy way — with must or had to

Change the order into the everyday form. Use must (for a rule now) or had to (for the past).

1. The priests demand that the gods be fed. → The gods be fed.

2. The emperor ordered that every town pay tribute. → Every town pay tribute.

3. The leaders insisted that the army return home. → The army return home.

1. must (a rule that is still true: "The gods must be fed.")

2. had to (a past order: "Every town had to pay tribute.")

3. had to (a past order: "The army had to return home.")

3. Finish the sentence

Put the verb in its base form after that. Remember: no to, no -s, and be for "to be".

1. The high priest demanded that the offering (be) ready at dawn.

2. The emperor insisted that Cortés (leave) the city.

3. The rules demanded that each town (send) gold and feathers.

1. be ("be ready", not "is ready")

2. leave (base form after "insisted that")

3. send ("each town send", no -s)

Easy version: "The offering must be ready", "Cortés had to leave", "Each town had to send gold."

You will use this in the Speak tab, when you make rules and orders of your own.

Listen

There is a real podcast about the Aztecs. It is for native speakers, so it is fast and quite difficult — that is normal! You do not need to understand every word.

🎧 Heard it already? Good — use this lesson as your recap, and listen for new details next time. Haven't? No problem — you now know the story and the key words, and that makes a fast podcast much easier to follow. The podcast is optional; this lesson works on its own.

While you listen:
  • Write down three words you hear and know from today's lesson (temple, god, empire, tribute, army…).
  • Can you hear the names Tenochtitlan and Moctezuma?
  • Find one new thing the podcast says, and tell me about it next time — even just one sentence.

Speak

Do all three tasks out loud. Use the timer to keep talking.

Useful language: for orders and rules, use must or had to ("The gods must be fed", "Every town had to pay tribute"), or the special form ("The priests demanded that the gods be fed"). To give an opinion: "I think…", "In my opinion…", "For me, the reason is…".
Time remaining: 3:00
Task A · Tell the story (3 minutes)

Tell the story of the Aztecs in your own words. Use these steps to help you: a poor tribe with no home → the eagle on the cactus → the great city on the lake → the empire and tribute → the strangers from the sea → illness and siege → the city falls in 1521.

Try to use some of the key words (temple, god, sacrifice, tribute, army, sign, conquer, siege), and at least once say what the priests or the emperor demanded or ordered (or what people had to do).

Task B · Why did the empire fall? (3 minutes)

The Aztec empire was very big, but it fell fast. What do you think was the main reason: the Spanish guns and horses, the illness (smallpox), or the angry people who hated the Mexica? Give your opinion and say why.

Task C · Rules and orders (3 minutes)

Tell a story or talk about rules of your own. Say what someone demanded, ordered or what people had to do — a rule, a tradition, or an order.

Not sure what to talk about? Choose one:

  • A famous city or country you like — and the rules its leaders made everyone follow.
  • A tradition or custom from your country — what people had to do, and why.
  • A strict teacher, coach or boss who ordered that things be done one special way.
  • If you ran a country for one day: three rules you would insist everyone follow.
  • A time when powerful people fell because the people under them turned against them.
  • A sign or superstition your family takes seriously — and what people must do about it.

To finish

  1. The Mexica believed the gods must be fed, or the world would end. How does a belief like this change the way a whole people lives?
  2. The Spanish wrote much of this story, and they wanted to show the Mexica as cruel. How should we read a story when one side tells most of it?
  3. Mexico City stands today on the ruins of Tenochtitlan, and the eagle on the cactus is on its flag. Why can a fallen empire still be a proud symbol for a country?
  4. From memory: say one sentence about the Aztecs with must or had to, and one with demand / order / insist that + a base verb. Why is there no -s on the verb?
