Episode Two : Conquest
Episode Two | Transcript
On November 15th 1532, 168 Spanish conquistadors arrive in the holy city of Cajamarca, at the heart
of the Inca Empire, in Peru.
They are exhausted, outnumbered and terrified – ahead of them are camped 80,000 Inca troops and the
entourage of the Emperor himself.
Yet, within just 24 hours, more than 7,000 Inca warriors lie slaughtered;
the Emperor languishes in chains; and the victorious Europeans begin
a reign of colonial terror which will sweep through the entire American
Why was the balance of power so unequal between the Old World, and the New?
Can Jared Diamond explain how America fell to guns, germs and steel?
Spaniard Francisco Pizarro has gone down in history as the man who conquered the Inca. Leading a small
company of mercenaries and adventurers, this former swineherd from a provincial town in Spain managed
to demolish one of the most sophisticated Empires the world has ever seen.
of the Spanish conquistadors
From Pizarro's home town of Trujillo, Jared Diamond pieces together
the story of the Spaniards' victory over the Inca, tracing the invisible
hand of geography.
On the surface, the Spaniards had discovered a foreign empire remarkably
similar to their own. The Inca had built an advanced, politically
sophisticated, civilization on the foundations of successful agriculture.
They had ruthlessly conquered their neighbors in South America, and
by 1532 governed a vast territory, the length and breadth of the Andes.
But as Jared discovers, the Inca lacked some critical agents of conquest.
Horses vs Llamas
Eurasia boasted 13 of the 14 domesticable mammals in the world as
native species. Among these was the horse.
As Diamond learns, the horse was fundamental to the farming success
of Eurasian societies, providing not only food and fertilizer but
also, crucially, load-bearing power and transport – transforming the
productivity of the land.
The only non-Eurasian domesticable animal species in the world was
the llama – native, by chance, to South America. The Inca relied on
llamas for meat, wool and fertilizer – but the llama was not a load-bearing
animal. Llamas can't pull a plow, nor can they transport human beings.
And unlike horses, llamas could never be ridden for war.
Spanish horsemanship, based on principles of cattle-herding, was famous
throughout Europe for its manoeuvrability and spontaneity –
skills learned by Pizarro's conquistadors in their youth. Horses could
charge, mounted soldiers could slay with brutal efficiency. Diamond
realizes that, to a people like the Inca, who had never seen humans
ride animals before, the psychological impact of these alien mounted
troops must have been huge.
Steel vs bronze
But Pizarro's men only brought 37 horses to Peru. So where did the rest of their shock value lie?
Well, once again, the Europeans had something the Americans didn't – they had steel.
For thousands of years throughout Eurasia, metal-working technology
had evolved from the simplest ore-extraction of the first Neolithic
villages, to the highly-sophisticated forging of steel, in cities
like Toledo and Milan. Geography had endowed Europe with rich sources
of iron and wood, and a climate conducive to high-temperature metallurgy.
Thanks to the geographic ease with which ideas spread through the continent of Eurasia, discoveries like gunpowder
could also migrate thousands of miles, from China to Spain.
And political competition within Europe fuelled a medieval arms race. Pizarro's conquistadors were armed with the
latest and greatest in weapons technology – guns, and swords.
The Inca, by comparison, had never worked iron or discovered the uses
of gunpowder. Geography had not endowed them with these resources.
Nor had they received technologies from other advanced societies within
the Americas. This included a technology even more critical to Spanish
success than their weapons, writing.
On the eve of battle, Pizarro and his men discuss how to tackle the
vast army of the Inca. It seems an impossible task. But they have
a secret weapon up their sleeve – the weapon of past experience.
Jared Diamond travels to the library of Salamanca University, to read for himself the published accounts of Hernan
Cortes' conquest of Mexico.
Only twelve years before Cajamarca, Cortes and his men had faced similar odds against the vast army of the Aztec
Empire. But somehow Cortes had captured the Emperor and conquered the land for Spain.
Cortes and his soldiers sent their written accounts back to the general public in Europe, where they were widely
published. Diamond discovers a repository of dirty tricks at Salamanca – a collection of handbooks for would-be
conquistadors. And on the eve of battle, it was the printed lessons of Cortes that inspired Pizarro and his men.
By contrast, the Inca Emperor Atahualpa had never heard of Cortes,
or even of his own neighbors, the Aztecs. Thanks to the geography
of the Americas, it was practically impossible for any ideas, technologies,
or even news, to spread from north to south. So whilst the Mayan civilisation
of Central America had invented a form of written communication, it
had never got as far as Peru. The Inca were isolated – and Atahualpa
had never even seen a book before.
So, when presented with a copy of the Bible on November 16th, 1532, Atahuallpa throws the alien object to the floor,
prompting a furious and surprise attack from the conquistadors. The combined impact of mounted troops, gunpowder and
sharpened steel lead to a massacre, and Atahuallpa is personally seized by Pizarro himself.
||Inca Emperor Atahualpa had never seen writing
In a matter of hours, the Inca Empire lies in ruins. But the story
of Eurasian triumph isn't over.
Lethal gift of livestock
Seven thousand Inca died at Cajamarca. Over the course of a generation, the Spaniards killed tens of thousands more.
But Diamond learns that up to 95% of the native population of the entire Americas were wiped out after the conquest.
Genocide alone can't account for this number.
Instead, he discovers, native Americans fell victim to European germs
– infections which they had never encountered before.
And Diamond realizes that European diseases like smallpox were a fatal
inheritance of thousands of years of mammal domestication –
the lethal gift of livestock.
European farmers, rearing cattle, pigs, sheep, goats, horses and donkeys, lived in close proximity with their animals
- breathing, eating and drinking animal germs. Eventually some diseases crossed over to the human population and the
resulting epidemics wiped out millions of Europeans.
But each time, a few people would survive and the immunities they'd
developed passed through their genes to the next generation. The conquistadors
who sailed to the Americas carried immunities like these.
But in Peru, the llama was never brought indoors, and never milked
so the prospect for the spread of disease was severely reduced.
But then the Europeans arrived and a single Spanish slave arrived,
infected with smallpox and the consequences were devastating. The
disease emptied the continent, killing millions of indigenous people
who lacked any prior exposure, and therefore any immunity. The European
triumph was complete.
So Diamond has shown how guns, germs and steel had conquered
the New World. But will his theories work in every corner of the globe?
Where to next?
