1. The Louisiana Purchase and Exploration The Louisiana Purchase and Exploration Chapter 10, Section 2

2. The West  In 1800 the “West” meant the area between the Appalachian Mountains and the Mississippi River.  The US border was the Mississippi River but there was a great deal of activity further west.

3.  After the French and Indian War Spain took control of the Louisiana Territory and New Orleans  Spain was a relatively weak neighbor and relations were generally good between the two.  In 1800, France and Spain began negotiating for ownership of the Louisiana Territory which returned to French control

4.  The Pacific Northwest and the Oregon country also drew increasing attention.  Spain, Russia, Great Britain, and the United States all claimed land in the region

5. The Mississippi River and New Orleans  Use of the Mississippi River and the port of New Orleans was vital to those living in the “west” so much so that they were willing to go to war to protect it.  After France regained control of the Louisiana territory, Jefferson offered to buy New Orleans from France.

6. The Louisiana Purchase  Napoleon offered to sell the United States the entire Louisiana territory for $15 million dollars or about 3 cents an acre.  This purchase would double the size of the United States

7. Reasons for Napoleon’s Offer  He was alarmed by America’s determination to keep the port open.  Revolts in the French West Indies may have lessened his desire for colonies.  The war with Britain was costly and made money more valuable than land.

8. Jefferson’s Dilemma  As a strict constructionist, the Constitution did not authorize the president to buy land.  Jefferson wanted a nation of small farmers which would be benefitted by having more land.  He decided to make the purchase

9. Lewis and Clark Explore  Meriwether Lewis Jefferson’s private secretary was chosen to lead the trip.  Lewis asked his friend Lieutenant William Clark to select and oversee a volunteer force.  Clark was a skilled mapmaker, and outdoorsman, and a strong leader
