CHAPTER THIRTY-ONE

Argentina, Chile, Peru, Etc.


CIVIL WARS, STRONGMEN, and the Fight to Fill the Spanish Vacuum

When Spain collapsed in the early 1800s,
South America fractured — not just from Europe, but from itself.

The colonial borders hadn’t been drawn to create nations.
They’d been drawn to extract resources.

So when the Spanish packed up and left,
the people left behind had to decide:
Where do the lines go now?

And the answer was:
Everywhere and nowhere.

Argentina wanted to be a republic.
Then it wanted to be a federation.
Then it couldn’t decide.

Buenos Aires — rich, coastal, and arrogant — fought the interior provinces constantly.
Civil wars broke out.
Caudillos (military strongmen) ruled like warlords.
And slowly, a national identity emerged — built on cattle, tango, and the myth of European sophistication.

Argentina’s borders were settled mostly by expansion and suppression.
It pushed into Indigenous territory in the south through the so-called “Conquest of the Desert” — a euphemism for land seizure and massacre.

Chile had geography on its side.
A giant noodle of coastline pinned between the Pacific and the Andes,
Chile’s natural borders were clear.

But it still fought for them.

In the War of the Pacific (1879–1884), Chile went up against Bolivia and Peru over control of nitrate-rich desert.
Chile won — and Bolivia lost its coastline, becoming the landlocked country it still is today.

The Chilean state expanded north, grabbed territory, and built a national identity that was tight, centralized, and military-minded.

It later fell into dictatorship under Pinochet,
but the borders held.

Peru was once the center of the Inca Empire — the greatest Indigenous power in the Americas before the Spanish arrived.

When independence came, Peru was both proud and precarious.
Its colonial borders had been huge — but neighboring countries all wanted pieces.

It fought Ecuador.
It fought Chile.
It fought Colombia.

Most of these wars were brief, but they redefined Peru’s shape over the 19th and early 20th centuries.

Internally, Peru remains divided — the coast, the highlands, the Amazon.
Each with its own culture, economy, and political gravity.

Other neighbors followed similar arcs:

  • Bolivia lost wars and land but never stopped dreaming of a coast.
  • Paraguay was nearly wiped out in the War of the Triple Alliance — a conflict so lopsided it borders on genocide.
  • Uruguay was born as a buffer state between Argentina and Brazil — and somehow pulled off stability while its neighbors fell into chaos.

The modern map of South America is relatively calm today.
But that’s recent.
And under the surface, many of these borders sit on unfinished wars, Indigenous dispossession, and unresolved national myths.

The lines look clean.
But the stories behind them are anything but.
