By the end of this section, you will be able to:
  • Describe the terms of the Wilmot Proviso
  • Discuss why the Free-Soil Party objected to the westward expansion of slavery
  • Explain why sectional and political divisions in the United States grew
  • Describe the terms of the Compromise of 1850

The 1848 treaty with Mexico did not bring the United States domestic peace. Instead, the acquisition of new territory revived and intensified the debate over the future of slavery in the western territories, widening the growing division between North and South and leading to the creation of new single-issue parties. Increasingly, the South came to regard itself as under attack by radical northern abolitionists, and many northerners began to speak ominously of a southern drive to dominate American politics for the purpose of protecting slaveholders’ human property. As tensions mounted and both sides hurled accusations, national unity frayed. Compromise became nearly impossible and antagonistic sectional rivalries replaced the idea of a unified, democratic republic.

The liberty party, the wilmot proviso, and the antislavery movement

Committed to protecting white workers by keeping slavery out of the lands taken from Mexico, Pennsylvania congressman David Wilmot attached to an 1846 revenue bill an amendment that would prohibit slavery in the new territory. The Wilmot Proviso    was not entirely new. Other congressmen had drafted similar legislation, and Wilmot’s language was largely copied from the 1787 Northwest Ordinance that had banned slavery in that territory. His ideas were very controversial in the 1840s, however, because his proposals would prevent American slaveholders from bringing what they viewed as their lawful property, their slaves, into the western lands. The measure passed the House but was defeated in the Senate. When Polk tried again to raise revenue the following year (to pay for lands taken from Mexico), the Wilmot Proviso was reintroduced, this time calling for the prohibition of slavery not only in the Mexican Cession but in all U.S. territories. The revenue bill passed, but without the proviso.

That Wilmot, a loyal Democrat, should attempt to counter the actions of a Democratic president hinted at the party divisions that were to come. The 1840s were a particularly active time in the creation and reorganization of political parties and constituencies, mainly because of discontent with the positions of the mainstream Whig and Democratic Parties in regard to slavery and its extension into the territories. The first new party, the small and politically weak Liberty Party    founded in 1840, was a single-issue party, as were many of those that followed it. Its members were abolitionists who fervently believed slavery was evil and should be ended, and that this was best accomplished by political means.

The Wilmot Proviso captured the “antislavery” sentiments during and after the Mexican War. Antislavery advocates differed from the abolitionists. While abolitionists called for the end of slavery everywhere, antislavery advocates, for various reasons, did not challenge the presence of slavery in the states where it already existed. Those who supported antislavery fervently opposed its expansion westward because, they argued, slavery would degrade white labor and reduce its value, cast a stigma upon hard-working whites, and deprive them of a chance to advance economically. The western lands, they argued, should be open to white men only—small farmers and urban workers for whom the West held the promise of economic advancement. Where slavery was entrenched, according to antislavery advocates, there was little land left for small farmers to purchase, and such men could not compete fairly with slaveholders who held large farms and gangs of slaves. Ordinary laborers suffered also; no one would pay a white man a decent wage when a slave worked for nothing. When labor was associated with loss of freedom, antislavery supporters argued, all white workers carried a stigma that marked them as little better than slaves.

explain how nature and nurture affect the development and later the productivity of an individual.
Amesalu Reply
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.
