Understanding the Louisiana Purchase in just five minutes
Oct 20, 2026
You may have noticed in the news lately that there
was a supposed desire by the US government
to purchase New Orleans from Denmark.
Now, while this sounds kind of crazy today, it's actually
how the United States got a lot of its territory,
like Alaska, Florida, or the place we'll be
talking about today, Louisiana.
The purchase of Louisiana was a gigantic step for the expansion
of the United States. The territory
of Louisiana spread across 15 current US states. Arkansas,
Iowa, Missouri, Kansas, Oklahoma, Nebraska,
Minnesota, Louisiana, New Mexico, Texas,
South Dakota, Wyoming, Montana, Colorado,
and even a little bit of Canada. Imagine if the US
hadn't bought this land or taken control of it by any other mean.
It would probably have stopped
their expansion west, dividing the future country in half
and containing the US in its current east
coast. Maybe California
and Texas would have still rebelled against Mexican rule, but remaining
independent and larger states.
Louisiana could have eventually declared independence from France
like the US did from Great Britain
and we would have four countries instead of one. Now, first of
all, what was Louisiana?
The Louisiana territory was part of France's North American colonies
from 1682 to 1762.
It's named Louisiana in honor of French King Louis XIV.
In 1763, France lost
the Seven Years' War against Great Britain.
In what seems to be an attempt to not have Britain
take the land, the French king, now Louis XV,
gave the land to his cousin, Charles III of Spain.
And so, Louisiana became a Spanish territory.
In 1800, however, with Napoleon now in charge of
France, he bought back the territory from Spain
as part of a broader project to re-establish a
French colonial empire in North America.
But France's colonial projects seemed doomed to fail.
Their failure to put down a revolt in another colony,
Saint-Domingue, plus the possibility of
a new war against the United Kingdom,
pushed Napoleon to consider selling Louisiana to the
United States and abandon his American colonial ambitions.
U.S. President Jefferson was really
happy about this because it had been his long-term goal
to purchase Louisiana and control the
Mississippi River, as well as the port of New Orleans.
His idea was to purchase it piece by
piece, but this way, he didn't need to wait.
And so, two years later, in 1803, the US bought the
territory from France, in return for $15 million,
or approximately $18 per square mile. That's a
pretty good deal. The American government used $3 million
in gold as a down payment, which Napoleon
supposedly used to finance his planned invasion of England,
which ended up never happening. The
treaty was negotiated by the French treasury minister acting
on behalf of Napoleon and
American delegates acting on behalf of President Thomas Jefferson.
But Jefferson didn't have such
an easy time achieving this goal,
facing a lot of domestic opposition. The Federalists,
a political party at the time, strongly opposed the purchase,
favoring close relations with Britain
over close ties to Napoleon
and were concerned that the US had just paid a large sum of money
to declare war on Spain,
which still technically administered the territory. Many were also
concerned about whether or not the purchase was constitutional.
A lot of members of the House of
Representatives opposed the purchase.
They called for a vote to deny the request, but it failed by
two votes, 59 to 57. It's crazy to think how close history came
to be completely different. Just two
votes. The Spanish themselves weren't too happy about this either,
claiming that France had
previously promised not to alienate Louisiana to a third party.
But in the end, everything worked
out. The Spanish Prime Minister authorized the US
to negotiate with the French government. Spain
turned the territory over to France in a ceremony
in New Orleans on November 30, a month before
France turned it over to American officials.
Later, on April 30 of 1803, the Louisiana Purchase
treaty was officially signed in Paris,
being announced by President Jefferson to the American
people on July 4th of that same year.
Like I said, the purchase of the land also helped the
expansion of the U.S. territory,
which with this nearly doubled in size overnight, also adding
60,000 new inhabitants to its population,
allowing them access to the Mississippi River Basin,
a gigantic plot of land, and a pathway to the West.
In his speech, Jefferson stated,
From this day, the United States take their place among the powers
of the first rank, demonstrating the incredible importance
that this purchase and the territorial expansion that came with it had
for the establishment of the United States as the country we know today
and paving the way for its future status as a world power.
