Transcript of The Louisiana Purchase and The Lewis & Clark Expedition

The Louisiana Purchase
Possible Reasons Why Napoleon offered the Louisiana Territory
Just before Spain returned the territory, Spain closed the New Orleans to American shipping.
Thomas Jefferson then offered to buy New Orleans from Spain for $2 million to avoid war between Westerns, France and Spain.
In return, the French denied his offered. Jefferson then offered $10 million for New Orleans.
The French approved it, and also offered $5 million more the the rest of the Louisiana Territory (the land between the Mississippi River and the Rocky Mountains).
The entire Louisiana Territory was then sold to the U.S. for 15 million dollars (3 cents per acre) on April 30, 1803. The U.S. doubled its size over night because of the purchase.
Spain and France were negotiating for the ownership of the Louisiana territory in 1800.
After the French and Indian War, France has turn over the Louisiana territory - including New Orleans to Spain.
But in 1801, Spain signed a secret treaty with France to return Louisiana Territory to France's powerful leader, Napoleon.

The Lasting Influence
Zebulon Pike's Expedition
In 1806, Lewis and Clark are assigned another task which is to venture off to the southern regions of Louisiana. However, this time it is led by Zebulon Pike. The mission was to find the sources of Arkansas and Red rivers. The Red river formed a boundary between Spanish territory and Louisiana. Instead of doing so, they ran into Rio Grande which was Spanish territory. This led them to getting arrested by Spanish troops. A year later in 1807, they were released.
