1. Jefferson and The Louisiana Purchase

2. The Louisiana Purchase
By 1800, more than a million settlers lived between the Appalachian Mountains and Mississippi River; still not allowed to use Mississippi River for trade (controlled by Spain)
Pinckney Treaty – negotiated to allow use of river – helpful for transporting goods
Crisis develops – Spain secretly gave New Orleans and Louisiana Territory to France
This disturbed Jefferson – worried about Napoleon Bonaparte taking over America or blocking American expansion

3. Buying Louisiana
Jefferson sends Monroe to France – able to purchase entire Louisiana Territory for $15 million (4 cents an acre) because Napoleon needed money
Haitians had driven French out – without that colony it was difficult to maintain control of Louisiana Territory
This purchase doubled the size of America

5. Lewis and Clark Explore the West
Newly acquired western land needed to be explored
Americans wanted to know if a waterway existed between the Mississippi River and Pacific Ocean
Also want Lewis and Clark to make contact with Natives living in this area

6. The Journey Began in St. Louis and head up Missouri River
Reach Platt River – meet Natives
Proceed to the eastern edge of Great Plains
Next they move to what is now North Dakota – meet the Mandan people and Sacagawea (Shoshone)
Hit the Rockies and Continental Divide – disappointed that they did not see a waterway to take them to Pacific
Shoshones agree to sell horses to help the expedition
Reach Columbia River and eventually Pacific Ocean

8. Pike’s Expedition
As Lewis and Clark travel back, Zebulon Pike also explores Louisiana Territory
Goes to Rocky Mountains – tries to climb a mountain – makes it up almost all the way – now called Pikes Peak
On his way home arrested by Spanish in New Mexico – thought he was a spy
Eventually released
This expedition created more interest in Spanish borderlands
