Manifest Destiny (????- 1850) APUSH Final Exam Review Project By: Kailee Weiler and Alexa Vagnozzi Manifest Destiny In the 1840’s the people of America began to believe that they were chosen by God to control the North American continent. Thus it became a factor which drove them to look west and claim new territory. Not only was it a movement to spread political system, but it was also to spread a racially defined society due the “American race” as the superiority. Texas The Mexican government began to encourage American immigration into Texas. They wanted to strengthen the economy and increase their own tax revenues. They also said that the settlers would create an effective buffer against US expansion in the region as they believed the settlers would soon become loyal. So they began offering land to immigrants. But friction grew between the settlers and the Mexican government. So when Dictator Santa Anna wiped out their cherished liberties, the Texans rebelled. After the Battle of San Jacinto, Sam Houston was able to make Santa Anna surrender and Texas would become independent. Now the only controversy was to annex it or not. Oregon With four countries having made claims to Oregon territory, it remained pretty much untouched due to the joint occupation treaty. But when missionaries under the idea of Manifest destiny began to come over a try to convert Indians, it sparked much resistance. Americans clamored for “54’ 40 or fight”, but Polk wanted to keep the peace. So Polk was able to propose a compromise which was the 49th parallel. It was accepted because the Senate did not want to war with Britain. The Westward Migration All migrants were in search of a new life, but of course they all had different visions of what that entailed. Some hoped to find gold while others wanted to take advantage of the land. But still most hoped to establish themselves while some were trying to escape the disease of the cities. Even though life on the trail was tough, families were able to continue dividing tasks along gender line and stick to their traditional views. And some even found it a highly collective experience. Elections of 1840 and 1844 For the election of 1840 it was Whig candidate William Henry Harrison vs. Democrat Martin Van Buren. John Tyler also ran on the Whig ticket too. Martin Van Buren was the hand-picked successor of Jackson but soon became known as “Martin Van Ruin”. The election of 1844 was Democrat James Polk vs. Whig Henry Clay. In preparing for the election both had to take a stand on the issue of annexing Texas. The South wanted to annex Texas while the North feared a disruption of the balance established by the Missouri Compromise. Polk was a strong believer in expansion and when he became president he sought three goals: annex Texas, Oregon, and California. Tyler had already annex Texas before leaving office, so Polk now tried to compromise over Oregon. After a debate the Senate approved a treaty that fixed the boundary of the US-Canadian border at the 49th parallel. Then he dealt with the boundary dispute over Texas and committed himself to acquiring both New Mexico and California for the US. The Mexican War Polk sent Slidell to Mexico to make an offer to buy California, but with the loss of Texas they refused. Also, the US saw the Rio Grande as the southern border of Texas while Mexico claimed it was the Nueces River. So when Polk ordered troops south of the Nueces and a clash occurred, Polk urged the Senate to declare war. American forces did well and were able to capture Monterrey, Santa Fe, complete the conquest of California, and then later seized the Mexican capital. After the capital was seized a new government took power and was willing to negotiate a peace treaty. Polk and the Mexican government reached the treaty of Guadalupe Hidalgo. But even though America gained new territory, it also acquired some new issues. Slavery and the New Territories, Sectionalism When new territories were introduced to the United States, slavery was a hot topic of debate in Congress. Adding slave states meant that the slave states vs. free states ratio was out of balance. Yet when slave states were not added, there were arguments. For instance, a piece of legislature called the Wilmot Proviso was introduced to Congress. It passed in the House, but not the Senate. It stated that all new territory in Mexico would be free. Clearly, many were against this idea. Polk eventually left office and Zachary Taylor took over. He felt that if the new territories reached statehood, then the slavery issue would somehow be resolved. The idea of popular sovereignty and letting the states decide for themselves was dubbed dangerous considering the events of Bleeding Kansas. Thus, Taylor simply wanted the states to be entered as free states. Unfortunately, this upset the balance and was frowned upon, considering many wanted the District of Columbia to be free of slaves as well. With this rising topic of slavery, sectionalism among the North and South was evident in the years to come. California Gold Rush In January of 1848, James Marshall had found traces of gold in the foothills of the Sierra Nevada. The owner of the mills wanted to keep the discovery quiet, but eventually, word broke out. Hundreds of thousands of people had migrated just to California for the search of gold. The mountains were completely occupied as cities, such as San Francisco, were empty. The majority of these people were men and they were known as forty-niners. They had abandoned everything they had, ranging from homes to farms to jobs to families. Accordingly, the gold rush had also attracted Chinese migrants. This was the start of the major immigration that Nativists disliked so much. Truly, most of the gold was fool’s gold, or simply, many forty-niners came up successful and didn’t even find gold. Once the rush was over, California was overwhelmingly diverse and populous. The Compromise of 1850 Once time came for admitting new territories as states, a clear compromise was in order. Henry Clay came up with a massive plan for the areas. California was to enter the Union as a free state which tipped the balance of slave vs. free. New Mexico and Utah became new territories and popular sovereignty would be the deciding factor for slavery or not. Texas had boundaries created. Texas was paid $10 million for relinquishing its claim to lands east of the Rio Grande. Accordingly, the Fugitive Slave Act was issued. This placed the authority of the federal government behind capturing and returning fugitive slaves. Last, the slave trade was outlawed in the District of Columbia. The Fugitive Slave Law created anti-slavery feelings. Vocabulary 1. “Civil Disobedience” – It was an essay that was written by Henry David Thoreau.

From the beginning of its creation, Americans have always had the lust for expansion. During colonial times, colonists fought Native Americans off their land for more territory. Purchases, such as the Louisiana Purchase, expanded the country into the Midwest. A term used by John O’Sullivan, Manifest Destiny, was the belief that the United States was destined to expand across the continent and conquer all territories. Truly, it would be a country that went from “sea to shining sea.” After purchases and the Mexican War, Congress needed to decide the futures of certain states. The hot topic of slavery was on everyone’s minds, and inevitably was the main subject. Although expansionism helped with national unity, it also stirred up the debate between free and slave states which created extreme sectionalism between the North and South. The promise of new territory was the goal for most Americans. Mexico had control over the southwest. To increase their economy, they invited Americans to migrant and settle in their territory. Eventually, Mexican leader Santa Anna turned against the immigrants that did not become loyal. Texan rebels surfaced and they fought for their independence. Independence was eventually granted and America saw that Texas was an opportunity they could not pass up. In between the strife in the southwest, Polk settled with Britain the 49th Parallel for Oregon, another conquest achieved. All that was left was the California and New Mexico territories, but Mexico refused to these regions the US. Polk issued soldiers to go past the Nueces River which the Mexican government recognized as their border. The government issued an attack on the Americans and the Mexican War had begun. With this, Congress started debating on whether or not they should stick with the war. Unfortunately, this caused some unrest within the country, but the fight for territory was still the main focus. In the end, California was conquered. In 1849, California’s existence was overwhelmingly convenient. At Sutter’s Mill, gold was discovered and this created the mad gold rush. Fortyniners left their homes, families and jobs in the search for gold. Resulting from this event was the increase of immigration. California became an extremely diverse and populous state. Therefore, the newly expanded nation felt triumphant and was proud of their accomplishments. However, the United States had many decisions to make over these new territories that ultimately resulted in sectionalism. The Missouri Compromise of 1820 created a balance between free states and slave states. For instance, Missouri became a slave state and Maine was introduced as a free state. Furthermore, slavery north of the 36’30 line was prohibited. Many anti-slavery congressmen proposed that the new territories would be free states. David Wilmot, a congressman from Pennsylvania, proposed the Wilmot Proviso. It stated that all new territories from Mexico would be declared as free. This piece of legislature passed in the House but not the Senate. Finally, in 1850, Henry Clay proposed a bill that would cover the bases that both the North and South wanted to see. The Compromise of 1850 consisted of many factors involving slavery. California would enter the Union as a free state. In the new territories of New Mexico and Utah, popular sovereignty was issued. Accordingly, the Fugitive Slave Act was created. This placed the authority of the federal government behind capturing and returning fugitive slaves. Last, the slave trade was outlawed in the District of Columbia. Although the North and South typically got what they wanted out of the compromise, the entire idea of slavery still affected increased the feelings of sectionalism. Therefore, manifest destiny seemed to be a foolproof expansion plan for the United States when on paper. However, it truly exploited the weaknesses and controversies that were simply waiting to boil over for the North and South. Essay #2 The issue of territorial expansion sparked considerable debate in the period 1800-1855. Analyze this debate and evaluate the influence of both supporters and opponents of territorial expansion in shaping federal government policy. The idea of Manifest destiny emerged in the 1840’s and said that the people of America were chosen by God to control the North American continent. But as Americans pushed West in hopes of territorial expansion, they encountered many problems. The North and South became increasingly belligerent towards each other specifically over the controversies of slavery. Due the nation annexing new lands, the status of slavery was on everyone’s minds. The Missouri Compromise which was supposed to settle this debate failed to prevent the conflict. So a dangerous crisis occurred. Although territorial expansion reflected the hopeful wishes of God, it only sparked a huge debate over slavery. Those who opposed Manifest destiny feared it would bring up the controversial issue of slavery and threaten the Union. Specifically, the North was synonymous for its abolitionist movement and thus would not compromise until slavery was eliminated. On the other hand, the South defended the institutions of slavery by saying it was “a positive system for white southerners who needed a labor force”. However on the positive side of Manifest Destiny, many saw this expansion as a symbol of nationalism. The proponents agreed with its idea but there were mixed opinions on if they should use force and how far should the nation expand. The Democrats favored the use of force to extend the border while the Whigs favored extension through diplomacy. Henry Clay, a Whig and solid opponents of territorial expansion, feared like the people of its potential to aggravate the issue of slavery. The Missouri Compromise had divided up the Louisiana Purchase and said all the territory north would not permit slavery while those in the south would. Yet this only fueled more debate when settlers were trying to spread from “sea to shining sea,” thus overstepping the boundaries of the compromise. So with Americans in Texas, Oregon county, New Mexico and California, the debate became even more heated. In Texas, after declaring its independence from Dictator Santa Anna, the debate was to annex it or not. Still everyone was questioning the issue of slavery. When Calhoun presented the annexation treaty to congress it was rejected and thus became the issue during the election of 1844. But before leaving office, John Tyler was able to accomplish one of Polk’s goals: the annexation of Texas. Additionally there were disputed claims in Oregon. With many countries claiming their rights to the land, the United States ended up compromising to the 49th parallel in order to stay clear of a war. But when the government was pushed into a The Mexican War, they were ultimately victorious. Therefore, through the constant debate over territorial expansion many aspects of the government were changed. To avoid war, the United States settled on a series of compromises throughout the era of Manifest destiny. But also it shaped the issues of the presidential elections. With the people disagreeing on slavery, it was ultimately up to the President to decide what to do. With the number of slave states equaling that of the free states, the admission of new states such as California, New Mexico, Oregon, and Utah would upset the balance. Thus the controversy continued while Americans were acquiring new lands. Now it was up to the power holders, specifically the government to decide the fate of the territories and the issue of slavery.

C – Since the colonial times, slavery took a prominent role in the lives of American citizens. Whites believed that slavery benefited them because they were able to have someone wait on them, and grow their crops. Essentially, slavery helped their businesses. They also believed that it helped the blacks because they thought they gave them a good life. A good life compared to maybe living in Africa or being freed without a job or home. 2. D – The South became an agricultural empire during the 1850s. Everything was grown and produced there. Accordingly, since demand was high, crop prices were also high. People kept buying all of the goods. 3. A – The Wilmot Proviso was created to help with the slavery issue after the Mexican War. The new acquired territories would be free along with a $2 million for making peace. 4. C – John O’Sullivan used Manifest Destiny for the first time. He meant it that it was America’s destiny from God to spread their white culture to the rest of continent and to conquer all. 5. D – Mexico had no desire to annex Louisiana considering it was purchased by the United States from the French. 6. B – The Missouri Compromise consisted of three pieces: Missouri is to be admitted as a slave state, Maine is a free state, and anything above the 36°30’ line would be free. 7. B – Specifically during Jackson’s presidency, Native Americans were extremely discriminated against. He frowned upon their existence and had them removed from their homes to be located to Oklahoma. This migration was called the Trail of Tears. 8. B – The British had the territory of Oregon that the United States wanted. The public started using the phrase, “Fifty-four forty or fight!” In reality, the government didn’t want to start a war with Britain, so Polk settled for a lower area. 9. C – The Compromise of 1850 consisted of California entering as a free state, and New Mexico and Utah were determined by popular sovereignty. Texas was paid for damages, the Fugitive Slave Act was issued, along with the slave trade being outlawed in DC. 10. A – Clearly, in the political parties’ name “Free-Soil,” they believed that all citizens of the United States deserved to be free. Thus, they wanted to stop the spread of slavery. 11. C – The United States was in a pretty good unity prior to the Mexican War. After the war and the acquired new territories, the topic of slavery became hot. There was a balance of free and slave states, thus new territories would disrupt that balance. Hence, the war created sectionalism between the North and South. 12. C – Jackson was against the creation of a National Bank. He felt that the bank only supported wealthy elites rather than the common man, which is who he represented. He did not approve the bank’s renewed charter, especially since its leader, Nicholas Biddle, was corrupt. 13. B – The Compromise of 1850 created an imbalance between the slave and free states. Because of this, it did nothing but create more tension and sectionalism than ever before. 14. D – When manifest destiny was the main goal for the United States, California and New Mexico were major territories that the country wanted. A situation took place when the Mexican army attacked Americans. This caused the Mexican War, which is ultimately what Polk wanted. 15. B – The Webster-Ashburton treaty focused on the territory regarding the Maine-New Brunswick border. It was mostly centered around the slave trade that was taking place. *borrowed from REA: AP US History
