CHAPTER TWENTY-SEVEN
United States
MANIFEST DESTINY AND the Art of Making a Country Bigger
The U.S. didn’t start big.
It started as a strip of colonies hugging the Atlantic — thirteen little rebels who declared independence in 1776
and promptly started arguing over land.
By 1783, they’d won the Revolutionary War.
Britain handed over a huge chunk of land all the way to the Mississippi River — land that wasn’t Britain’s to give, by the way.
It was Indigenous land, already lived on, already claimed.
Didn’t matter.
The U.S. considered it open for settlement — which meant conquest.
The country grew fast, violently, and unapologetically.
- 1803: The Louisiana Purchase — bought from France, despite being full of Native nations
- 1819: Florida — bought from Spain, also full of people who didn’t agree
- 1845–1848: Texas joins, then the U.S. goes to war with Mexico and grabs the southwest
- 1853: The Gadsden Purchase — just tidying up the corners
- 1867: Alaska bought from Russia — they called it “Seward’s Folly”
- 1898: Hawaii, Puerto Rico, Guam, and the Philippines are taken — now we’re an empire baby
And within all of that?
Indigenous dispossession, forced relocation, and extermination.
The U.S. didn’t just expand.
It erased.
Internally, the borders kept shifting.
States were added, split, and renamed.
Territories became states.
Reservations were drawn and redrawn.
The Mason-Dixon Line became a fault line for slavery and civil war.
And even today, some of the most contentious borders in the U.S. aren’t international — they’re internal.
Red state vs. blue state.
South vs. North.
Urban vs. rural.
Reservations carved inside state lines.
Gerrymandering inside counties.
The U.S. map looks stable.
But it’s a battlefield of political geography.
On the outside, the borders froze in place after World War II.
But the influence didn’t stop at the edge.
U.S. military bases dot the globe.
Territories like Puerto Rico, Guam, American Samoa, and the U.S. Virgin Islands remain in constitutional limbo — part of America, but not fully American.
The U.S. doesn’t need to redraw maps anymore.
It draws policy, trade, and culture — and lets those do the work.
Because sometimes, the strongest borders aren’t on land.
They’re in influence.
