What was the importance of the purchase and exploration of the Louisiana Territory?

The tide of westward settlement speeded up in the years after

America’s independence.

By 1800, more than one million settlers lived between the Appalachian Mountains and the Mississippi River.

Farmers shipped goods down the Mississippi to the port of New Orleans.

Most western settlers were farmers who relied on the Mississippi River.

From there, goods were loaded on ships and carried to markets across the Atlantic.

Spain, which controlled the Mississippi River and New Orleans, threatened to close the port to American ships.

Pinckney Treaty

This treaty guaranteed

Americans’ right to ship goods down

the Mississippi River to New Orleans.To prevent this, the

U.S. negotiated the Pinckney Treaty with Spain in 1795.

Westerners demanded war with

Spain.

Later, after the treaty had been signed, Spain withdrew Americans’ right to ship goods through New Orleans.

Jefferson feared that France would become dominant in America, as it was becoming in Europe.

If this happened, westward expansion of

the United States would be blocked.

French territory

To make matters worse, Jefferson learned that Spain had secretly given its Louisiana Territory to France.

Jefferson decided to try to buy New Orleans from the French.

He sent James Monroe and Robert Livingston to Paris to make a deal.

When they arrived in France, they discovered that the situation had shifted yet again.

Without Haiti, France would have trouble defending Louisiana in the event of a war.

The French had been driven from their colony on Haiti.

Also, war between France and Britain was looming.

Napoleon needed money for the war.

Britain France

Because of France’s situation, Monroe and Livingston received a surprising offer.

France offered to sell the entire Louisiana Territory to the United States.

LouisianaNew Orleans

Jefferson hesitated to approve the purchase.

In the end, Jefferson decided that the purchase was constitutional because the President is able to make treaties with foreign countries.

Was it constitutional?

After buying the Louisiana Territory in 1803, Thomas Jefferson was eager to have it explored and mapped.

In 1803, Jefferson convinced Congress to fund a western expedition.

Meriwether Lewis

He chose two army officers to lead the exploration.

William Clark

Goals of the western expedition

Report back on the natural features of the

region.

Look for a waterway from the Mississippi to the Pacific

Ocean.

Make contact

with Native Americans.

Lewis and Clark left St. Louis in the spring of 1804 and explored the northern part of the Louisiana Territory.

Lewis and Clark’s expedition lasted for over two years.

July 1804 August 1804 October 1804

The party reached the mouth of the Platte River,

which feeds into the Missouri

River.

The expedition followed the

Missouri River from St. Louis to the

Rocky Mountains.

July 1804 August 1804 October 1804

They met with Native

Americans for the first time.

The Americans promised to give the tribes military

support and trading rights in exchange

for peace.

July 1804 August 1804 October 1804

They camped in what is now

North Dakota for the winter.

They were joined by Sacagawea, a

Shoshone translator.

August 1805 November 1805 March 1806

The party reached the continental

divide.

They did not find a waterway to the

Pacific. Instead, they had to navigate

rapids in their canoes.

August 1805 November 1805 March 1806

They reached the Pacific

Ocean by way of the Columbia

River.

They began the return journey,

which took about half a

year.

The journey of Lewis and Clark led many Americans to feel a sense of duty to expand west.

From 1805 to 1807, Zebulon Pike explored the southern part of the Louisiana Territory.

Pike’s reports increased U.S. interest in the region.

Pike headed west to the Rocky Mountains.Partway up a mountain, he was forced to turn back.

Today, this mountain is known as Pike’s Peak.

Pike returned home through Spanish New Mexico.

Pirates from the North African Barbary States began attacking American ships.

America paid money to the rulers of the Barbary States.

The Barbary pirates stopped attacking American ships.

At first, America paid tribute, as other nations did.

Pirates from the Barbary State of Tripoli captured the American ship, Philadelphia.

Jefferson stopped paying tribute. He sent warships to protect American merchant ships.

American sailors led by Stephen Decatur burned the Philadelphia so the pirates could not use it.

This victory and others inspired confidence in America’s ability to deal with foreign threats.

A greater threat to America came from Britain and France.

United States

In 1803, Britain and France were at war. The United States remained neutral and profited by trading with both nations.

France Britain

Britain and France weakened each other by cutting off each other’s foreign trade.

France seized American ships trading with Britain.

BritainFrance

Britain did the same to ships trading with France.

U.S.

U.S.

Once again, Britain used impressment to gather soldiers for the war with France.

Thousands of Americans were forced to serve in the British navy.

Jefferson used a peaceful method to force Britain and France to respect American neutrality.

Jefferson predicted that the embargo would stop Britain and France from attacking American ships.

He imposed an embargo on American ships sailing to any foreign port.

The embargo hurt America in many ways.

Prices of American crops declined.

Many Americans lost

their jobs.

Merchants turned to smuggling to survive.

embargo

Congress repealed the Embargo Act in 1809, just before Jefferson left office.

Congress passed a new law that reopened trade with all countries except France and Britain.

America would reopen trade with those countries when they started respecting America’s neutrality.

As American settlers moved west, they took over Native American lands.

Also during this period, tens of thousands of American settlers moved westward.

• Many died from new diseases.

• They lost their hunting grounds.

• Animals they hunted were driven away.

• The power of their leaders declined.

Native Americans suffered from this expansion.

Shawnee leader Tecumseh organized the western tribes into a league to resist settlement.

William Henry Harrison took action against Tecumseh’s activities.

Harrison sent soldiers against Shawnee villages while Tecumseh was away. Tippecanoe

River

However, Native Americans never regained their strength after the Battle of Tippecanoe.

Tecumseh and his allies continued their opposition to western settlement.

In the Battle of Tippecanoe, Harrison defeated the Native Americans.

What were the causes and effects of the War of 1812?

Tension with Britain was high when James Madison took office in 1809.

Britain armed Native Americans…

…and continued impressment of U.S. sailors.

American anger toward

Britain

Many Americans felt a new sense of American nationalism at this time.

In 1810, nationalists Henry Clay and John C. Calhoun joined the House of Representatives.

They and their supporters were called war hawks. They supported war with Britain.

The British vowed to continue impressment.

Relations with Britain worsened steadily in early 1812.

In June 1812, Congress declared war on Britain.

Native Americans began new attacks on settlers.

The war did not come at a good time for the British, who were still at war in Europe.

However, Britain refused to meet American demands to avoid war.

America Britain France

Americans were confident that they would win the war. However, the U.S. was not prepared.

Jefferson’s spending cuts had weakened the military.

The navy had only 16 warships ready for action.

The army had fewer than 7,000 soldiers.

The War of 1812 was fought on several fronts.

One important area was along the Atlantic coast.

In August 1812, the USS Constitution defeated the British warship Guerrière in the North Atlantic.

The ship’s thick wooden hull earned it the nickname “Old Ironsides.”

Despite the victory of the Constitution, Britain was able to set up a blockade of the American coast.

Britain had closed off all American ports by the war’s end.

The Great Lakes and the Mississippi River were also important fronts.

In July 1812, the British defeated American troops in Canada. They captured over 2,000 U.S. soldiers.

Both sides won key battles during the war in the West.

In 1813, U.S. troops led by Oliver Hazard Perry won control of Lake Erie at the Battle of Put-In-Bay.

Oliver Hazard Perry’s victory at Lake Erie was a key victory for the Americans.

The British were forced to retreat back into Canada.

U.S. troops pursued and defeated the British in the Battle of the Thames.

Native Americans suffered defeat both in Canada and in the South.

In March 1814, U.S. troops led by Andrew Jackson defeated Creek warriors at the Battle of Horseshoe Bend, in Georgia.

The treaty that ended the

fighting forced the Creeks to

give up millions of acres of land.

In 1814, the British defeated Napoleon.

This allowed Britain to send many more troops to fight against America.

America FranceBritainBritain

Many New Englanders opposed the war, because the British blockade was hurting their trade.

As the war dragged on, Federalists expressed their opposition by calling it “Mr. Madison’s War.”

In 1814, opposition was so high that delegates at the Hartford Convention suggested that New England secede from the United States.

The British made their final attacks in 1814.

In August 1814, they attacked Washington, D.C.

The President fled; the capitol was burned.

On September 13, they moved on to Fort McHenry in Baltimore.

Americans won this battle, which also inspired the U.S. national anthem.

Britain had tired of war. On Christmas Eve, 1814 the two sides signed the Treaty of Ghent.

Before this news reached the U.S., Americans won a final victory in the Battle of New Orleans in January 1815.
