00:00Today we are talking about the strangest empire in human history.
00:03The Aztecs.
00:05In 1519, the Aztecs were at their absolute peak.
00:08Their capital, Tenochtitlan, sat in the middle of a lake,
00:11home to well over a hundred thousand people, larger than any city in Spain.
00:15Nobody standing in that city would have believed anything was wrong.
00:1921 months later, it was rubble.
00:21The standard story says a few hundred Spaniards did it, with steel and gunpowder and horses.
00:26But when Cortes landed, he had about 500 men.
00:29The real army that tore that city apart was almost entirely indigenous.
00:33Tens of thousands of them.
00:35And they came from one small state, Tlaxcala.
00:38The Aztecs in Tlaxcala had been at war for 70 years, and the Aztecs had never beaten them.
00:43Those 70 years made Tlaxcala the one army on earth that truly knew how to fight the Aztecs.
00:48And the way those wars were fought was strange.
00:50The time and place were agreed in advance.
00:53How many men each side would send was agreed in advance.
00:56Everyone went home afterwards and came back the next year.
00:59Those wars had a name, the Flower Wars.
01:02It sounds like performance art.
01:04But for the Aztecs, it was necessary, because this so-called empire was not an empire the
01:08way we understand the word.
01:10When they took a city, they usually changed nothing.
01:13No governor.
01:14No new laws.
01:16No new gods.
01:17They even let the old king keep his throne.
01:20Only one thing changed.
01:22From that day on, you paid tribute each year.
01:25What you paid, how much, and by what date, all written down in a ledger.
01:29When the Spanish arrived, they ordered Aztec scribes to rewrite those records, province
01:33by province, listing exactly who owed what.
01:36How many blankets, how much cacao, how many feathers.
01:39There were 38 such tribute provinces, running from the Gulf of Mexico to the Pacific.
01:44Tax collectors lived right there among the people, watching them pay.
01:47If a province failed to pay, the army came back and tore down its main temple in front
01:51of the whole city.
01:52In other words, this was not a state.
01:55It was a protection racket.
01:57And a protection racket has a built-in flaw.
01:59Rome held its provinces with roads and legions.
02:02The Aztecs held theirs with reputation.
02:05Inland, they had almost no standing army and no governors.
02:08That system was cheap and scaled fast, millions of people paying tribute, with almost nobody
02:13sent to run them.
02:14But reputation expires.
02:16When the old king dies, every province immediately starts calculating.
02:20Does this new man, this new king, really have what it takes?
02:23So every new king's first act was to find somewhere and win a war.
02:27Win, and the payments continue.
02:29And there was a second, harder reason they had to fight every year.
02:33The Aztecs believed the world had already ended four times.
02:36Theirs was the fifth son.
02:38And that son had been paid for by a god's own sacrifice, a debt never fully settled.
02:43So every time the son climbed out of the east, it had to be fed.
02:46And it was fed with the blood of the conquered.
02:49The entire society was organized around capturing the living.
02:52Boys trained for war from childhood.
02:55A commoner who dragged back enough live captives could be made a noble.
02:58So the goal in battle was odd.
03:00Not to kill the enemy, but to take him alive.
03:03And that habit would later cost them everything.
03:06So they fought every year.
03:08But land is finite.
03:09The easy targets were gone.
03:11The rest were either too far or too strong.
03:14And so the flower wars were born.
03:16Chosen ground.
03:18Equal numbers.
03:19The same handful of opponents, over and over.
03:22If both sides bleed at the same rate, the smaller one runs dry first.
03:26The Aztecs sent out only a fraction of their men each time, and still removed a large chunk
03:31of their enemy, year after year.
03:33In other words, this was not ritual.
03:35This was slow, deliberate bloodletting.
03:37And it worked.
03:39In the same generation, other rivals were crushed.
03:42Cholula was simply swallowed.
03:44By 1519, Aztec garrisons held city after city.
03:48Only Tlaxcala remained.
03:50The Aztecs ate away at its neighbors, closed the ring, boxed Tlaxcala into its own valley.
03:55Eventually even salt could not get in.
03:57Even that most basic trade was cut.
04:00And Tlaxcala still would not bow.
04:02The price the a-
04:03A blade does not get tired.
04:05A blade also does not forget.
04:07In 1519, the thing that blade was waiting for landed.
04:10The moment Cortez came ashore, he scuttled his own ships, cutting off any thought of return.
04:15The first to revolt were not the Tlaxcalans, but coastal peoples who had been taxed and
04:19humiliated.
04:20They seized the collectors, stopped paying, and told the Spanish that these men had stripped
04:24the land bare.
04:25Only then came Tlaxcala.
04:27At first, they fought the Spanish, and nearly finished Cortez.
04:31But in the fighting they saw one thing clearly, these outsiders had something the Aztecs had never
04:35shown them.
04:36So they did not bow.
04:38They negotiated.
04:40Three conditions.
04:41We keep our independence.
04:43We get a share of the spoils.
04:45And you tear down that empire.
04:47For 70 years they refused to kneel to the Aztecs.
04:50They had no intention of kneeling to these newcomers either.
04:53Then came the most famous disaster of the whole story.
04:56In 1520, while Cortez briefly left the capital, his deputy, Alvarado, attacked an unarmed crowd
05:02at a festival.
05:03The city exploded.
05:05Moctezuma died in that chaos.
05:07The Spanish were driven out, fighting across the causeways, losing hundreds of Spaniards
05:11and thousands of allies.
05:13By any logic, the story ends there.
05:15A beaten remnant, in a strange land, with the retreat cut off.
05:19Tlaxcala took them in, sheltered them, fed them, and helped them rebuild.
05:23In other words, the army that later destroyed Tenochtitlan was assembled by Tlaxcala, piece
05:28by piece, from the wreckage.
05:30After that, it was an avalanche.
05:32Texcoco, one of the founding members of the Aztec alliance, switched sides and brought
05:36half its forces over.
05:38And then smallpox arrived.
05:40It swept the valley.
05:42Even the new Aztec ruler, Quitlowak, could not survive it.
05:45He had been on the throne 80 days.
05:47And by this stage, the lifelong skill of taking captives became a fatal flaw.
05:52One sharp analysis, Aztec warriors went into battle thinking about how to drag a man away.
05:57Their opponents were thinking about how to put a man down.
05:59When those two styles collide, the first one loses.
06:03The siege of the capital lasted 93 days.
06:06The Spanish launched 13 ships built specifically for that fight, cut the causeways, and cut
06:11the city's fresh water.
06:12On the 13th of August, 1521, the city fell.
06:16Years later, Cortez offered an explanation.
06:19He claimed Moctezuma told him, we could have destroyed Tlaxcala whenever we wanted, but we
06:23kept it to take captives and train soldiers.
06:25Consider who is speaking.
06:27If Cortez came back empty-handed, he faced charges of treason.
06:31So he needed this to be a war that was always going to be won, not a war where locals
06:35carried
06:35him.
06:36Was Tlaxcala deliberately spared, or simply never?
06:38When Cortez landed, he did not have to build an army capable of destroying the Aztecs.
06:43That army already existed.
06:45It had waited in the valley for 70 years.
06:47And the people who built it were the Aztecs themselves.
06:50We like to imagine the fall of a civilization as an accident.
06:54Outsiders arrived with better weapons.
06:56But Tenochtitlan was not destroyed by outsiders.
06:59The army that destroyed it used its own methods, tested its own weaknesses, and carried 70 years
07:04of hatred, sharpened point by point.
07:06Anything that survives by making people afraid must always leave one person at the door who
07:10is not afraid.
07:11Because if every enemy is gone, it can no longer prove to anyone that it can still fight.
07:15So it keeps one.
07:17Year after year.
07:19Sparring with it, year after year.
07:21And it always believed it was sharpening a blade.
07:24Only in the end did it discover that the one being ground down was always itself.
