In 1 853, the Sadden Purchase added about 30,000 square miles of Mexican rewriter to the United States and fixed the boundaries of the “lower 48” where they are today. In 1 845, a journalist named John Sullivan put a name to the idea that helped pull many pioneers toward the western frontier. Westward migration was an essential part of the republican project, he argued, and it was Americans’ “manifest destiny,” to carry the “great experiment of liberty” to the edge of the continent: to “overspread and to possess the whole of the [land] which Providence has given us,” Sullivan wrote.The survival of American freedom depended on it.
Westward Expansion and Slavery Meanwhile, the question of whether or not slavery would be allowed in the new western States shadowed every conversation about the frontier. In 1 820, the Missouri Compromise had attempted to resolve this question: It had admitted Missouri to the union as a slave state and Maine as a free state, preserving the fragile balance in Congress. More important, it had stipulated that in the future, slavery would be prohibited north of the southern boundary of Missouri (the 36030′ parallel) in the rest of the Louisiana Purchase.However, the Missouri Compromise did not apply to new territories that were not part of the Louisiana Purchase, and so the issue of slavery continued to fester as the nation expanded. The Southern economy grew increasingly dependent on “King Cotton” and the system of forced labor that sustained it. Meanwhile, more and more Northerners came to believed that the expansion of slavery impinged upon their own liberty, both as citizens-the pro-slavery majority in Congress did not seem to represent their interests-?and as yeoman farmers.They did not necessarily object to slavery itself, but they assented the way its expansion seemed to interfere with their own economic opportunity.

Westward Expansion and the Mexican War Despite this sectional conflict, Americans kept on migrating West in the years after the Missouri Compromise was adopted. Thousands of people crossed the Rockies to the Oregon Territory’, which belonged to Great Britain, and thousands more moved into the Mexican territories of California, New Mexico and Texas.In 1 837, American settlers in Texas joined with their Techno neighbors (Texans of Spanish origin) and won independence from Mexico. They petitioned to join the United States as a slave state. This promised to upset the careful balance that the Missouri Compromise had achieved, and the annexation of Texas and other Mexican territories did not become a political priority until the enthusiastically expansionist cotton planter James K. Polk was elected to the presidency in 1844.Thanks to the maneuvering of Polk and his allies, Texas joined the union as a slave state in February 1846; in June, after negotiations with Great Britain, Oregon joined as a free state.
That same month, Polk declared war against Mexico, claiming (falsely) that he Mexican army had “invaded our territory and shed American blood on American soil. ” The war proved to be relatively unpopular, in part because many Northerners objected to what they saw as a war to expand the “slaveholder. In 1846, Pennsylvania Congressman David Willow attached a proviso to a war-appropriations bill declaring that slavery should not be permitted in any part of the Mexican territory that the U. S. Might acquire. Willow’s measure failed to pass, but it made explicit once again the sectional conflict that haunted the process of westward expansion. Westward Expansion and the Compromise of 1 850 In 1 848, the Treaty of Guadalupe Hidalgo ended the Mexican War and added more than 1 million square miles, an area larger than the Louisiana Purchase, to the united States.
The acquisition of this land re-opened the question that the Missouri Compromise had ostensibly settled: What would be the status of slavery in new American territories? After two years of increasingly volatile debate over the issue, Kentucky Senator Henry Clay proposed another compromise. It had four parts: first, California would enter the Union as a free state; second, the status of slavery in the rest of the Mexican territory would e decided by the people who lived there; third, the slave trade (but not slavery) would be abolished in Washington, D.C. ; and fourth, a new Fugitive Slave Act would enable Southerners to reclaim runaway slaves who had escaped to Northern states where slavery was not allowed. Bleeding Kansas But the larger question remained unanswered. In 1854, Illinois Senator Stephen A. Douglas proposed that two new States, Kansas and Nebraska, be established in the Louisiana Purchase west of Iowa and Missouri.
According to the terms of the Missouri Compromise, both new states would prohibit leaver because both were north of the 36030′ parallel.
