CHAPTER TWENTY-NINE

Mexico

AZTECS, SPAIN, THE U.S., and a Map That Got Smaller

Mexico’s story doesn’t begin with Mexico.

It begins with Tenochtitlán — a floating city of canals, temples, and stone causeways built by the Aztecs.

It was one of the most sophisticated urban centers in the world when, in 1519,
Hernán Cortés landed with a few hundred Spaniards, some horses, and a god complex.

Two years later, the empire was gone.

For the next 300 years, the land became New Spain —
a massive colony that stretched from California to Costa Rica, with its capital in modern-day Mexico City.

Spain extracted silver, converted souls, and built a colonial economy on Indigenous backs.

But by the early 1800s, the cracks began to show.

Inspired by revolutions in the U.S. and France, and fueled by centuries of resentment,
Mexico declared independence in 1810 — and won it by 1821.

What followed was… not peace.

Mexico spent the next few decades as a political mess:

• Emperors crowned and overthrown
• Republics founded and refounded
• Coups, betrayals, and backroom deals
• And most importantly: land loss

In 1836, Texas declared independence.

In 1845, the U.S. annexed Texas.

In 1846, war broke out.

By 1848, Mexico had lost half its territory — including California, Arizona, New Mexico, Nevada, Utah, and parts of Colorado and Wyoming.

Then came the Gadsden Purchase in 1854 — a final border tweak to tidy up the southern edge of Arizona and New Mexico.

Mexico’s northern border froze, and hasn’t moved since.

But the turmoil didn’t end.

In 1862, France invaded and installed a puppet emperor (yes, really).
Mexico kicked him out.

In 1910, the Mexican Revolution exploded — a massive, decade-long civil war that reshaped land ownership, government power, and class warfare.

Out of it came the modern Mexican state — a fragile democracy ruled for decades by one dominant party, the PRI.

Today, Mexico’s borders are stable.
But the legacy of conquest, revolution, and lost territory hangs heavy.

Internally, the real lines are now drawn by:

• Cartels, who control regions like shadow governments
• Migration routes, shaped by U.S. policy and economic desperation
• Cultural borders, between the urban elite and rural poor
• And the ghost border of Aztlán — the dream of a pre-American Southwest that still lives in art, politics, and memory

Mexico lost land.
But it never lost identity.
