What was the impact of the Westward Expansion on the institution of slavery in America?

Irma Morteo

The Westward Expansion had a substantial impact on the institution of slavery in America. As the country extended its territorial boundaries, so did the struggle between pro-slavery and anti-slavery forces. The expansion, starting from the Mississippi River and stretching all the way to the Pacific Ocean, created new territories and states, where the issue of slavery became a subject of intense debate.

The Westward Expansion of the United States brought forth a significant change. As new territories and states were added to the Union, it became clear that the existing compromise over slavery could no longer suffice. The dust of the Mexican-American War had yet to settle when the U.S. Congress introduced the Wilmot Proviso in 1846. This draft legislation would have banned slavery in any territory acquired from Mexico. Although the Proviso failed to pass in the Senate, it marked an important progressive movement for anti-slavery advocates.

However, the issue of slavery had become more complicated than a matter of morality. The land acquired by the United States as a result of the War had presented unique economic opportunities, particularly in the mining industry. Pro-slavery advocates believed that enslaved labor was necessary to profit from those opportunities. The question surrounding slavery, therefore, no longer merely reflected a struggle between morality and economics, but rather reflected a clash between different forms of economic self-interest.

The institution of slavery played a substantial role in the rapid expansion of the United States. Yet, this rapid expansion brought into question the ability to maintain the balance of power between slave-holding and free states. The Compromise of 1850 allowed for the addition of California as a free state in the Union, but it also introduced the Fugitive Slave Act, which required Northern citizens to help law enforcement officials capture escaped slaves.

The Kansas-Nebraska Act of 1854 dealt a fatal blow to the equilibrium between free states and slave-holding states. This legislation essentially put an end to the Missouri Compromise of 1820, which had prohibited slavery in the territories north of the parallel 36°30'. More territories opened up to slavery's expansion, converting the American West from a potential haven for free labor to a new battleground for the struggle between pro-slavery and anti-slavery forces.

The issue of slavery in the West brought regional political parties into the spotlight. The Republican Party emerged in the late 1850s with the aim of halting the spread of slavery into Western territories. And while the party had yet to resonate with Southern states, it earned support from numerous Northern abolitionists who believed that limiting slavery's growth could ultimately lead to its demise.

In conclusion, the Westward Expansion was a turning point in the history of slavery in America. It opened up new territories and states and brought new challenges and opportunities. But with these opportunities came new issues - political struggles, economic interests, and slavery's ever-expanding reach into new regions. The Westward Expansion marked a point of no return in the fate of slavery in America, as more divided and contentious than ever before. However, it also laid the groundwork for the eventual end of enslavement, paving the way for the United States to move beyond its past and towards brighter days.
