1Lesson 10.2: The Louisiana Purchase and Exploration Today’s Essential Question: What was the importance of the purchase and exploration of the Louisiana Territory?
2Vocabulary surplus – more than what is needed or used nomadic – moving from place to place, without a permanent homeexpedition – a journey of explorationheadwaters – where a river begins
3Check for Understanding What is today’s essential question?What do some people do with their surplus clothing?What are some people or animals that might be described as nomadic?What is an expedition that you would like to be part of?Which direction would you go to find any river’s headwaters?
4What We Already KnowThomas Jefferson wanted America to remain a nation of small towns and independent farmers.
5What We Already KnowEven before the war for independence, Americans were eager to move west into new lands.
6What We Already KnowFor years, Western farmers had depended on access to the port at New Orleans to get their surplus produce to eastern markets.
7As Americans moved west, they entered three distinct geographic regions.
8Trans-Appalachia Wooded; rolling hills and flatlands Well-watered Humid summers, cold wintersSettlers by the thousands moving in, displacing the Native Americans
9The Great Plains Flat, rolling plains Rocky Mountains Great Basin (desert)Treeless; few riversHot, dry summers; bitterly cold wintersFrance and SpainNomadic Plains Indians (horse culture)Non-migratory Indians in the Southwest
10The Pacific CoastMild weather; rainy in the Northwest, dry in the SouthwestSierra Mountains, Cascades, Coast Ranges, Central ValleyMany natural harborsSpain, Russia, Britain, the United States in competitionMany Indian groups of various cultures
11The West in 1800In the 1800s, thousands of settlers moved westward across the Appalachian Mountains.Kentucky and Tennessee had become states by 1800.
12The West in 1800France and Spain were negotiating for ownership of the Louisiana Territory – the vast region between the Mississippi River and the Rocky Mountains.
13The West in 1800Along the Pacific coast, Spain, Russia, Great Britain, and the United States were establishing settlements.
14The West in 1800As 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.
15Check for Understanding A ask B: What city was most important for many westerners in the early 1800s?Be sure to re-state the question in your response!
176. Why was New Orleans important to Americans? It was surrounded by mountain ranges that made it easy to defend in times of war.It was a port city for farmers and merchants living in the Ohio Valley.It guarded the entrance to the Mississippi River.It was the banking and manufacturing center of the nation.
18Napoleon and New Orleans After losing the French and Indian War in 1763, France turned Louisiana over to Spain.In 1800, Spain secretly agreed to return the Louisiana Territory, including New Orleans, to France.
19Napoleon and New Orleans Just before turning the colony over to France, Spain closed New Orleans to U.S. ships, in violation of the Pinckney treaty.Angry Westerners called for war against Spain and France.To avoid war, Jefferson offered to buy the port of New Orleans from France for $2 million.France offered to sell the entire Louisiana Territory to the United States for $15 million.
20Napoleon 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.
21Napoleon and New Orleans 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.
22Napoleon and New Orleans In 1801, a slave named Toussaint L’Ouverture led a violent slave uprising against the French colonists.
23Napoleon and New Orleans Though Napoleon sent in French troops, they were unable to put down the revolt.Without a profitable slave colony to feed, Louisiana was of no use to Napoleon.
24Check for Understanding B ask A: Who was Toussaint L’Ouverture?Be sure to re-state the question in your response!
25Napoleon and New Orleans Napoleon also was involved in a costly war with Britain.He decided he needed money more than he needed Louisiana.
26Napoleon and New Orleans Napoleon also feared he might lose New Orleans to the aggressive Americans.It would be better to sell it than have it be over-run by American settlers.
27Check for Understanding A ask B: Why was Napoleon willing to sell Louisiana to the United States?Be sure to re-state the question in your response!
28Jefferson and Louisiana New Orleans as an outlet for shipping the products of Western farmersMore land for farming, which was consistent with his vision for America’s futureAccess to the Pacific and trade with Asia
29The Louisiana Purchase Jefferson’s dilemma: strict construction of the Constitution or the greatest land deal of all time.On April 30, 1803, the Louisiana Purchase treaty was approved by the Senate, giving the United States the port of New Orleans and doubling the size of the country.
317. Why did Jefferson question his right to buy the Louisiana Territory? Three other nations had legal claims to the region.The Constitution said nothing about a president's right to buy land.He had been elected but had not yet taken the oath of office.To do so would put the nation in debt.
32Lewis and Clark Explore After purchasing the Louisiana Territory from France, Jefferson planned an expedition to explore it.He chose Captain Meriwether Lewis to lead the expedition.Lewis chose his old friend Lieutenant William Clark to put together a volunteer force for the trip.Clark was skilled as a mapmaker and outdoorsman.The expedition called itself the Corps of Discovery.
33Lewis and Clark Explore Lewis and Clark spent several weeks gathering a group of volunteers.They stayed in the town of St. Louis throughout the winter.In May 1804, the explorers left St. Louis and headed up the Missouri River.
34Lewis and Clark Explore Clark was accompanied by York, his African-American slave.York’s hunting skills won him many admirers among the Native Americans met by the explorers.The first black man that many Indians had ever seen, York became something of a celebrity among them.
35Up the Missouri RiverIn May 1804, the explorers left St. Louis and headed up the Missouri River.Jefferson had given their mission three goals:1. use the Missouri and Columbia Rivers to find a water route across the country;2. establish good relations with Native Americans along the way;3. and write scientific accounts of the landscapes, plants, and animals they saw.
378. What were the three goals of the Corps of Discovery? Find a water route to the Pacific Coast using the Missouri and Columbia Rivers.Establish friendly relations with the Indians.Scout out locations for future American military bases.Gather geographic and scientific information.Defeat and drive out any hostile Indians that might threaten future settlers.Be sure to choose three!
38Up the Missouri RiverBy winter, the explorers had reached North Dakota, and stayed with the Mandan Indians.In the spring of 1805, the expedition set out again accompanied by Sacagawea, a Shoshone Indian woman.Her language skills and knowledge of geography helped Lewis and Clark.
39On to the Pacific OceanAs the explorers traveled toward the Rocky Mountains, Sacagawea pointed out Shoshone lands.When they finally made contact with the chief, he recognized Sacagawea as his sister.With the help of the Shoshone, the Corps of Discovery crossed the Rocky Mountains.
419. How did Sacagawea help Lewis and Clark? She served as their guide, because she knew a safe route to the Pacific Coast.She had great knowledge of the local geography and of several language skills.She helped them escape execution at the hands of a warlike Indian group known as the Mandans.She helped them find a way back to the Missouri River on their journey home.
42On to the Pacific OceanAfter leaving the Shoshone, the Corps of Discovery then journeyed to the Columbia River, which led them to the Pacific Ocean in 1805.They spent a long, rain-soaked winter there before starting back to St. Louis the next spring.
43On to the Pacific Ocean In 1806, the explorers returned to the East. They brought back valuable scientific and geographic information.
44Check for Understanding B ask A: What information did the Lewis and Clark expedition bring back?The Lewis and Clark expedition brought back a wealth of scientific and geographic information.Be sure to re-state the question in your response!
45Pike’s ExpeditionIn 1806, Zebulon Pike left St. Louis to explore southern areas of Louisiana.Pike’s mission was to find the headwaters of the Arkansas and Red Rivers near Spanish territory.Pike’s party followed the Arkansas River toward the Rocky Mountains, then turned south.
46Pike’s ExpeditionHoping to run into the Red River, they instead ran into the Rio Grande, in Spanish territory.They were arrested by Spanish troops and held prisoner until 1807.They returned with important descriptions of the Great Plains and the valley of the Rio Grande.
47Check for Understanding A ask B: Who was Zebulon Pike?Zebulon Pike was an Army officer who led an expedition into the southern part of the Louisiana Territory.Be sure to re-state the question in your response!
48Check for Understanding B ask A: What information did Pike’s expedition bring back?Pike’s expedition brought back important descriptions of the Great Plains and the valley of the Rio Grande.Be sure to re-state the question in your response!
