Columbus and the Columbian Exchange

Columbus carried 17 ships on his second voyage. On them were horses, cattle, pigs, and smallpox. Within 50 years, 90% of the people he'd found were dead.

Ninety percent of the people who lived in the Western Hemisphere in fourteen ninety two were dead within about a hundred years.

Say that number out loud and most people picture soldiers, horses and steel.

The record does not agree. Old World diseases, smallpox, measles, influenza, typhus, killed an estimated fifty six million people across the Americas by sixteen hundred. The pathogens moved faster than any army, or any rumor of one.

They killed so many people, so fast, that the farmland they left behind grew back into forest, and the forest pulled enough carbon out of the air to show up in ice cores drilled in Antarctica today. That is not a metaphor. That is measured.

Scene 1Guanahani, October fourteen ninety two

Columbus wades ashore on an island the Taino call Guanahani. He plants a flag and claims it for Ferdinand and Isabella of Spain.

The Taino paddle out to greet the three ships. They bring cotton thread, parrots, and food. Gifts, not weapons.

Columbus writes it all down in his own diary, the same day.

Columbus, describing the people who had just fed him.

“They should be good servants and intelligent, for I observed that they quickly took in what was said to them, and I believe that they would easily be made Christians, as it appeared to me that they had no religion.”

Two days later, on the next island, Columbus writes the sentence that finishes the thought.

“With fifty men they can all be subjugated and made to do what is required of them.”

Before he sails on, he takes six Taino by force.

Commissioned by the United States Congress for the Capitol Rotunda. Vanderlyn depicts Columbus planting the Spanish royal banner on the shore while Taino figures watch from the margins, a 19th-century American reimagining of a Spanish colonial moment, painted to serve a third empire's origin story.

Scene 2The document nobody could hear

Fifteen thirteen. The Spanish Crown produces a text called the Requerimiento.

It informs Indigenous peoples that the Pope has granted Spain their land, that the King of Castile is now their lord, and that refusal means war, enslavement, and the loss of their children.

It is read aloud, in Spanish, by men in armor on horseback, to people who do not speak Spanish, sometimes from a distance at which no one could hear it at all. Then the attack begins.

Gonzalo Fernandez de Oviedo, the Crown's own chronicler, recorded that the jurist who drafted it, Juan Lopez de Palacios Rubios, laughed when told how it was used in the field.

What that meant in practice: a legal formality that made conquest lawful on paper before a single sword was drawn, satisfied by reading words no listener understood.

Bartolome de las Casas, the Dominican friar who later spent his life fighting this system, called it unjust, impious, scandalous, irrational, and absurd.

Scene 3The thing that arrived first

By fifteen twenty, smallpox has crossed the ocean and reached the mainland ahead of any Spanish army.

It reaches Tenochtitlan before Cortes does. It kills the Aztec emperor Cuitlahuac within the year.

It reaches the Inca Empire before Pizarro does. It kills the Sapa Inca, Huayna Capac, and triggers the civil war that Pizarro then exploits.

Two hemispheres had been separated for twelve thousand years, since the land bridge at Beringia went under water. The Old World had spent that time building a disease environment out of crowded cities and domesticated cattle, pigs, and horses. Indigenous Americans had none of the immunity that bought.

Scene 4What went the other way

The exchange runs in both directions. New World crops reach the Old World and rebuild it from the ground up.

The potato, grown in the Andes for thousands of years, reaches Europe and grows in soil where wheat will not. Maize reaches West Africa by the fifteen fifties and becomes a staple crop across the continent. The tomato reaches Italy by fifteen fifty. Italian food as the world knows it today did not exist before this.

Tobacco builds the plantation economies of Virginia and the Carolinas. Sugar cane, an Old World crop planted in New World soil, creates a demand for labor that the Old World then fills from a third continent.

Scene 5The mountain that ate people

Fifteen forty five. The Spanish find a mountain of silver at Potosi, in what is now Bolivia.

They adapt an Inca labor draft. Every adult man in the surrounding provinces owes four months a year underground, by candlelight, in tunnels where the temperature reaches forty degrees. Mercury used to extract the silver poisons the water and the workers.

An estimated eight million people work Potosi over three centuries. It produces forty five thousand tons of silver, which funds the Spanish crown's wars in the Netherlands.

And as the Taino die faster than they can be replaced on Hispaniola, the Spanish Crown authorizes a new labor source. Twelve and a half million enslaved Africans will be shipped across the Atlantic before the trade ends.

Five accounts

Five accounts of one exchange, and the first one was written to be believed by a king.

  1. Spanish Imperial
  2. Taino / Indigenous Caribbean
  3. Ecological / Biological
  4. World-Systems / Capitalist Origins
  5. African Diasporic

The turn

And here is what each account cannot hold at the same time as its own case.

  1. Spanish Imperial

    The Spanish imperial account leaves out the scale of the collapse it caused, ninety percent of a hemisphere, and the disease that did most of that killing.

    From the record
    The scale of demographic collapse (90% population loss) as a consequence of colonization
    The role of disease as the primary mechanism of Indigenous death
    The forced labor system that killed millions at Potosi and in the encomiendas
    Indigenous resistance, military and cultural, across two continents
  2. Taino / Indigenous Caribbean

    The Taino account does not separate what the sword did from what the microbe did. Both killed. The record does not always say which one, in which death.

    From the record
    Taino cultural practices including ball courts, zemis, and agricultural systems (conucos)
    Inter-island Taino trade networks and political complexity before contact
    The role of disease as distinct from deliberate violence in population collapse
    Post-colonial Taino cultural revival movements in Puerto Rico and the Dominican Republic
  3. Ecological / Biological

    The ecological account leaves out the massacres, the enslavement, and the mutilations that happened alongside the disease, as if biology alone explains what people chose to do.

    From the record
    The deliberate violence (massacres, enslavement, mutilation) that accompanied disease
    The political and economic structures that organized exploitation of survivors
    Indigenous agency in resistance, adaptation, and survival
    The moral dimension of European culpability versus epidemiological inevitability
  4. World-Systems / Capitalist Origins

    The world systems account leaves out the person. It can describe eight million forced laborers as a labor supply and never once describe what that labor felt like from underneath.

    From the record
    Indigenous cultural and intellectual contributions to the exchange
    The experience of enslaved individuals, the human reality behind the structural analysis
    Pre-Columbian trade networks and economic systems in the Americas
    Environmental and ecological dimensions beyond the economic frame
  5. African Diasporic

    And the African diasporic account is the one most often left out of the other four, and it leaves out the African kingdoms and elites who were partners in the trade, not only its victims.

    From the record
    Internal African political dynamics and the role of African elites in the slave trade
    Enslaved peoples' cultural preservation, spiritual practices, and community-building in the Americas
    Maroon communities and slave revolts as modes of resistance
    The abolition movements and their complex relationship with colonial economics

Close

By fifteen forty eight, fewer than five hundred Taino are left on Hispaniola. A quarter of a million people, gone in fifty six years.

But a two thousand eighteen genetic study found that modern Puerto Ricans carry, on average, fourteen percent Indigenous ancestry.

It survived through the bodies of women who had no say in the matter. They were not asked. They were not erased either.
