4. What We Already Know

8. What We Already Know
American settlers always had the desire to continue moving. Prior to the War of Independence, the British tried to limit
westward expansion by issuing the Proclamation of 1763 prohibiting settlement west of the crest of the Appalachian Mountains

9. What We Already Know
In 1800 the western boundary of the United States was the Mississippi River

10. The West in 1800
By 1800, thousands of settlers moved westward across the Appalachian Mountains. Into the Ohio River Valley and beyond.
By 1800, Kentucky and Tennessee became states.

11. The West in 1800
As the number of westerners grew, so did their political power. An important issue for many settlers was the use of the Mississippi River and the port of New.
Orleans. Westerners used the river and port to send their goods to east coast markets

12. The Louisiana Purchase
Twice, once in 1784 and again in 1801 The Spanish government closed the port of
New Orleans to Americans to discourage their movement west hoping to block them from moving to Spanish territory west of the Mississippi.

13. Napoleon and New Orleans
Almost immediately after the second blockade, Spain, in a secret treaty, gave the Louisiana Territory to France in exchange for a principality in Italy that Napoleon had conquered.

14. Napoleon and New Orleans
When details of the secret treaty became known, it both angered Jefferson and worried him. If Napoleon turned his aggression toward America, he could choke off western expansion by controlling New Orleans.

15. Napoleon and New Orleans
With second blockade angry western settlers called for a war against Spain and France. To avoid war, Jefferson offered to purchase New Orleans for $2million.

16. Napoleon and New Orleans
Jefferson’s offer of $2 million for New Orleans was rejected. When the offer was increased to $5 million, Napoleon, offered not only New Orleans, but the entire Louisiana Territory for $15 million.

17. Napoleon and New Orleans
Napoleon had several reasons for selling the land. The first reason had to do with a profitable French colony in the Caribbean called Santo Domingo.

18. The Louisiana Purchase
All the land on Santo Domingo was used for growing sugar, so food had to be grown elsewhere. Napoleon planned to
use land in the Louisiana Territory for farms to feed the slaves in Santo Domingo.

19. Napoleon and New Orleans
In 1801, a slave named Toussaint L’Ouverture led a violent slave uprising against the French colonists.

20. Napoleon and New Orleans
Even though napoleon sent in his most elite troops, he was unable to put down the revolt. Without a profitable slave colony to feed, Louisiana was of no use to Napoleon. (L’Ouverture won the revolution and renamed the colony The Republic of Haiti.)

21. Napoleon and New Orleans
Napoleon also feared he might lose New Orleans to the aggressive American settlers. It would be better to sell it than have it be over-run by American settlers.

22. Napoleon and New Orleans
Napoleon also was involved in a costly war with Britain. He decided he needed money more than he needed Louisiana.

23. The Louisiana Purchase
Jefferson has a dilemma. As a strict Constitutionalist, Jefferson did not believe he alone had the authority to make the greatest land deal in history.
On April 30.
1803, the Senate approved the purchase, nearly doubling the size of the country.
