Manifest Destiny

Main Idea

Americans in large numbers followed trails to the West in the 1840s and 1850s.

Americans Head West

• Few gave thought to how manifest destiny would affect native peoples.

• Five groups that went west:

1. Mountain men went west to trap and trade.

2. Missionaries hoped to convert Native Americans to Christianity.

3. Lumberjacks and miners went to capitalize on timber and minerals.

4. Farmers moved west to farm vast, rich lands.

5. Entrepreneurs made their way to California.

Americans believed in manifest destiny, the idea that the nation had a God-given right to all of North America.

Manifest Destiny

Manifest Destiny Activity

• Look at the painting and list as many themes, messages, symbols as possible. What does the woman mean? What is in her hands? Why is there darkness in ½? Who are the groups of people? What about the animals shown? What else is shown?

Meaning of the Painting

• Pictures were painted to encourage people to fulfill their Manifest Destiny. The picture below (Library of Congress LC-USZC4-668) shows 'America' floating over the Plains. She brings light to the dark and desolate landscape and shows the way for farmers, travelers, the stage-coach, the telegraph and the railway. Ahead of her wild animals, buffalo and Indians (the darkness) turn and run leaving the way clear for settlement.

How Settlers Went West:

• There were three major trails to the West that settlers took.

• Each one had a specific purpose and route.

3 Major Western Trails

The 2,000-mile Oregon Trail stretched from Independence, Missouri, to the rich farming lands of the Willamette Valley in Oregon. It was used by Native Americans, Lewis and Clark, fur traders and mountain men, and finally migrants.

1. Santa Fe Trail

The first major western trail was the Santa Fe Trail, which stretched 800 miles from Independence, Missouri, to the town of Santa Fe, the capital of Spanish New Mexico. It began as a trade route.

2. Oregon Trail

Between 1847 and 1853, some 16,000 Mormons migrated west following the 1,300-mile route that became known as the Mormon Trail. It ran from Nauvoo, Illinois, to Salt Lake City in present-day Utah.

3. Mormon Trail

News from Sutter’s Mill

In 1848 gold was discovered in the American River at John Sutter’s sawmill in northern California.

When the news reached the rest of the United States, most thought it was a rumor.

President James K. Polk talked about the gold discovery in his State of the Union address on December 5, 1848.

Newspapers across the country printed the story, and thousands of Americans caught “gold fever.”

The Gold Rush

California gold• The gold rush was a mass

migration of miners and people who made money from the miners to California.

• The migrants who left for California in 1849 were called forty-niners.

• Golden dreams brought people from all over the world, but 80 percent came from the United States.

Getting there• By land following the

California Trail is how most of the migrants moved to California to look for gold.

• By 1854 as many as 300,000 people had migrated to California. Review: How many people are needed to become a state?

Booming cities

• When most miners reached California, they moved into mining camps in the gold fields.

• Many other groups—especially businesspeople—settled in cities.

• San Francisco, the port nearest the gold fields, grew from

800 people in 1848 to some 25,000 the next year.• (stop) Think about what would happen if Topeka grew

that fast?• Stockton and Sacramento also grew rapidly during the

gold rush.

2 Major Effects of Westward Migration

1. The Oregon Treaty

• 1844 Presidential candidate James K. Polk promised to get the Oregon Country for the United States even if it meant war.

• The United States and Britain had both controlled Oregon since 1818.

• Polk won and made a treaty with Britain, that set the boundary between the United States and British Canada at the 49th parallel.

2. Communication Links

• Westward migration also led to the need for business, government, and personal communication over long distances.

• Butterfield stagecoaches went between St. Louis and San Francisco on a two-week trip with mail and people.

• Pony Express mail service used relays of young riders on fast horses between Missouri and California.

Texas Independence

The Main Idea

American settlers in Texas revolted against the Mexican government and created the independent Republic of

Texas.

Reading Focus

• How did Americans begin to move into Texas?

• What were the causes and effects of the Texas Revolution?

The Spanish Settle Texas: Background

The original inhabitants were Native Americans, living in Texas for thousands of years.

The Spanish explorers were the first Europeans to visit Texas, as early as the 1500s. Spain claimed Texas based on these explorations. Finding little wealth in the region, they made no attempt to settle permanently.

In 1689, the Spanish discovered the ruins of a French fort built on the coast that had been destroyed by local Indians. Afraid that the French would try to claim the land, the Spanish came up with a plan to settle Texas.

The Spanish Settle Texas: The Plan

The mission system• The Spanish attempted to

settle Texas by building missions, small settlements meant to convert the Indians to Christianity.

• The Spanish had effectively used the mission system in Mexico.

• They built two dozen missions between the late 1600s and 1700s; they also built San Antonio.

• Despite Spanish hopes, the missions failed and the towns never flourished.

Why the mission system ends

• Native Americans rejected mission life, because they were expected to give up their culture AND their religion.

• Some Indian groups saw the Spanish as trespassers, attacking the missions and towns.

• The system was meant to convert the Indians and to stop French claims. In 1762, France gave to Spain most of its land in North America.

• By 1800, Spain still claimed Texas, but had only three settlements in the area.

Americans Move into Texas

• Moses Austin

– In 1820, Austin made a deal with Spanish colonial officials that, in exchange for land, he would build a colony in Texas. The Spanish agreed, but Austin died before he could start. His son, Stephen F. Austin, would carry out his deal. By 1824 about 300 families lived on farms and ranches throughout Austin’s colony.

• Mexican independence and the empresarios

– Mexico gained its independence in 1821. The new government wanted Texas settled. They gave large amounts of land to empresarios, contractors who recruited settlers and established colonies. Austin was the most successful of the empresarios.

– By 1830, Texas had more than a dozen colonies with 30,000 settlers. Including several thousand enslaved Africans and 4,000 Tejanos, or Texans of Mexican heritage.

The Texas Revolution

The settlers ignored the Mexican rules. They kept bringing in slaves, even after Mexico outlawed slavery. Settlers were still Americans, not Mexican. In 1830, Mexico passed a law halting American immigration and sent troops to Texas to enforce it.

Tensions in Texas

Mexican officials suspected that the U.S. wanted to get Texas. Originally it was part of the Louisiana Purchase, but the U.S. had dropped its claim to it. But when the U. S. offered to buy a large part of Texas for $1 million, Mexicans refused, and their fears of U.S. plans were confirmed.

International tensions

American settlers in Texas had to agree to certain conditions in exchange for receiving land. They had to give up their American citizenship; swear allegiance to Mexico; adopt the Roman Catholic religion; and hold the land for seven years.

The Texas Revolution Begins

Tensions between settlers, now calling themselves Texans, and the Mexican government grew continually worse.

After several bloody protests, Texans held meetings to discuss the best course of action. A plan to make Texas a separate Mexican state failed. The new Mexican president, Antonio López de Santa Anna, supported a strong central government and enforced new laws banning state militias.

War came when violence erupted at Gonzales over possession of a cannon. Though small, it was the first battle of the Texas Revolution, and hopes for a peaceful resolution between the Texans and Mexico were gone. At a meeting, called the Consultation, the settlers founded a government and asked Sam Houston to raise an army.

From the Alamo to Independence

On February 23, 1836, Santa Anna’s force of 6,000 soldiers reached San Antonio. Santa Anna’s demand to surrender was returned by cannon fire from William Travis. The Mexican army laid siege to the fort, for 12 days and nights. The fort was finally stormed, with nearly all defenders killed.

The AlamoRebel Texan forces captured San Antonio, which contained a fort called the Alamo. Santa Anna led an army into Texas to punish the rebels and stop the protests for good.

Santa Anna

While the Alamo was under siege, a small group of Texans met at Washington-on-the-Brazos to issue the Texas Declaration of Independence. They wrote a constitution for the new, independent nation.

March 2, 1836

Fighting for Independence

The Runaway Scrape • Santa Anna’s army continued

to defeat the Texan rebels. Prisoners were held in the fort at Goliad.

• After Mexican soldiers executed 340 prisoners at Goliad, Houston retreated to the east with his poorly trained army.

• Word of Houston’s retreat and the news of the Goliad Massacre started a panic.

• In what would be called the Runaway Scrape, thousands of Texans, including many Tejanos, fled Santa Anna’s advancing army.

Texans victorious• Santa Anna’s army followed

Houston’s forces to San Jacinto, where Houston managed to take the Mexican army by surprise. Texans shouted, “Remember the Alamo!” and “Remember Goliad!” as they won a quick victory.

• The captured Santa Anna was forced to sign the Treaties of Velasco, ending the war. Mexico had to withdraw its troops and recognize Texas independence.

• Problems with Mexico continued for the Republic of Texas.

War with Mexico

The Main Idea

Soon after annexing Texas, the United States declared war on Mexico.

Reading Focus

• What were the arguments for and against the annexation of Texas?

• What created tensions between the United States and Mexico in the 1840s?

• What were the causes and effects of the Mexican-American War?

The Annexation of Texas

Proponents• Americans who believed in

Manifest Destiny wanted to admit Texas to the Union.

• Supporters viewed the Texas Revolution like the American Revolution.

• Southerners supported annexation because Texas allowed slavery, and its admission would boost the South’s political power.

Opponents

• Americans were concerned that the U.S. would have to pay the large Texas debt.

• Northerners opposed annexation because it would spread slavery westward and increase slave states’ voting power in Congress.

• A major argument in Congress was that the Constitution said nothing about admitting an independent nation.

The Annexation of Texas

• A Republic for nine years– The annexation question was a significant issue in the 1844

presidential election. When James K. Polk, the pro-annexation candidate, won, Mexico warned that it would consider the annexation of Texas as a declaration of war.

• Tyler signs the joint resolution – Outgoing president John Tyler signed the joint resolution of

Congress into law just three days before the end of his term, in March 1845.

• Texas becomes a state– Voters in Texas overwhelmingly approved annexation, and

Texas became a part of the United States on December 29, 1845.

Tensions between the United States and Mexico

In March 1845, James K. Polk became president. He wanted the nation to acquire the land between Texas and the Pacific Ocean. These sparsely populated territories, New Mexico and California, belonged to Mexico. Polk sought an opportunity to acquire these remote regions.

Mexico responds

The annexation of Texas enraged the Mexican government. Mexico had refused to recognize the Republic of Texas, and they broke off diplomatic ties with the U.S. after the vote for annexation.

Polk and Manifest Destiny

The U.S. needed to secure the boundary between Texas and Mexico. Texans put the border at the Rio Grande. Mexico maintained it was at the Nueces River. There were also disputes about money, and Polk wanted these issues resolved.

The boundary dispute

Slidell’s Trip

In the fall of 1845, Polk sent a special representative to Mexico.

John Slidell arrived with a U.S. offer to cancel the $3 million in claims against Mexico in exchange for Mexico’s recognition of the Rio Grande as its boundary with the U.S.

He was also told to pay Mexico up to $30 million to purchase New Mexico and California for the United States.

Neither of the rivals for Mexico’s presidency would meet with him. An angry Slidell recommended to Polk that Mexico be punished.

The Mexican-American War

American forces under Taylor advanced into northern Mexico. General Winfield Scott marched his forces into Mexico City. In a matter of months, U.S. forces had captured New Mexico and California. When their capital fell, the Mexican government was forced to give in.

The war starts

While Slidell was in Mexico, Polk ordered General Zachary Taylor to take his troops into the disputed border territory. The U.S. used the event of a minor fight to declare war on Mexico.

Fighting the war

The Treaty of Guadalupe Hildago (1848) forced Mexico to turn over a huge tract of land known as the Mexican Cession, while the U.S. paid Mexico $15 million. Debate continues over whether the Mexican-American War was justified.
