Slavery Compromises and Sectional Conflict in United States History

The Missouri Compromise ($1820$)

• Conceptual Background

  • Prior to the expansion of the United States in the early $19^{\text{th}}$ century, a delicate balance was maintained between free states and slave states in the Senate.

  • The primary objective of these compromises was to preserve the Union by managing the geographical expansion of slavery and maintaining political equilibrium between Northern and Southern interests.

• The First Large-Scale Compromise: Missouri Compromise ($1819$-$1820$)

  • Proponent: Proposed and navigated through Congress by Henry Clay, who earned the moniker "The Great Compromiser" for his role in this and future legislation.

  • Year of Initiation: $1819$.

  • The Core Issue: In $1819$, the territory of Missouri applied for admission to the Union as a slave state. At that time, the United States consisted of $11$ free states and $11$ slave states. Admitting Missouri as a slave state would have granted the South a majority in the Senate, disrupting the legislative balance.

  • The Problem Caused: Northern politicians opposed Missouri's entry as a slave state without restrictions, while Southerners argued that Congress did not have the authority to limit slavery in new states. The debate threatened to fracture the Union along sectional lines.

  • The Final Agreement (The Three Pillars):

    • Missouri: Admitted to the Union as a slave state.

    • Maine: To maintain the Senate balance, Maine (formerly a part of Massachusetts) was admitted as a free state. This brought the total to $12$ free states and $12$ slave states.

    • The $36^{\circ} 30'$ Line: Slavery was officially prohibited in the remainder of the Louisiana Territory north of the $36^{\circ} 30' \text{ North Latitude}$ line. Slavery was permitted in territories south of this line, with the exception of Missouri itself, which lay north of the line but remained a slave state.

Expansion and Sectional Tension in the $1840$s

• Historical Context: $1820$ to $1840$

  • Following the passage of the Missouri Compromise in $1820$, the United States experienced a period of relative calm regarding the expansion of slavery.

  • As the nation expanded its borders westward during the $1840$s, driven by the philosophy of Manifest Destiny, the issue of slavery's status in newly acquired lands was reignited.

• Lands Acquired from Mexico

  • The question of slavery became critical following the annexation of Texas and the acquisition of the Mexican Cession after the Mexican-American War.

  • Acquired Regions: Texas and the Southwestern United States (including present-day California, Nevada, Utah, Arizona, and New Mexico).

• Unsuccessful Proposals

  • Multiple proposals were introduced to handle slavery in these territories, but none proved acceptable to both the North and the South.

  • Northern interests frequently pushed for the total prohibition of slavery in newly acquired lands, while Southern interests demanded that the property rights of slaveholders be protected throughout the West.

The Compromise of $1850$

• The Crisis in the Southwestern Territories

  • Background: The discovery of gold in California in $1848$ led to a massive population surge, prompting California to apply for admission directly as a free state in $1849$.

  • The Issue: California's admission as a free state would once again tip the balance of power in the Senate against the South, leading to threats of secession from Southern leaders.

• Stipulations of the Compromise of $1850$

  • 1. California: Admitted as a free state, giving the North a legislative advantage.

  • 2. New Mexico and Utah Territories: Organized without specific mention of slavery. The status of slavery in these areas would be decided by "popular sovereignty," meaning the settlers themselves would vote on whether to allow slavery.

  • 3. Fugitive Slave Act of $1850$: A much stricter federal law was enacted to satisfy Southern demands. It required citizens to assist in the capture of runaway enslaved persons and denied accused runaways the right to a jury trial.

  • 4. Slave Trade in Washington, D.C.: The public sale and trade of enslaved persons were abolished in the nation's capital, though slavery itself remained legal there.

  • 5. Texas Border Dispute: Texas relinquished its claims to New Mexico territory in exchange for $10 \times 10^6$ dollars (written as $10,000,000$) from the federal government to pay off its state debts.

Debate, Opposition, and Political Impact

• The Great Debate in Congress

  • The compromise was the subject of intense debate between legendary orators: Henry Clay (the author), Daniel Webster (representing Northern nationalists), and John C. Calhoun (representing Southern sectionalists).

  • Support: Moderates who believed the compromise was the only way to prevent a civil war and the dissolution of the Union.

  • Opposition:

    • Northern Abolitionists: Opposed the Fugitive Slave Act, viewing it as a gross violation of human rights and an overreach of federal power.

    • Southern "Fire-eaters": Opposed the admission of California as a free state and any restrictions on the expansion of slavery.

• Impact on Enslaved Persons

  • The Fugitive Slave Act of $1850$ had a devastating effect on both escaped enslaved people and free Black citizens in the North. Many were kidnapped or legally forced into slavery without due process, and the risk of capture forced thousands to flee to Canada.

• Election Results and Political Shifts

  • The fallout from these compromises began to shift political party alignments. The Whig Party began to dissolve, and the debate paved the way for the rise of the Republican Party, which focused on preventing the further expansion of slavery.

Conflicts in the Louisiana Territory (The Kansas-Nebraska Context)

• Background and Issue

  • The original Missouri Compromise had settled the issue of slavery in the Louisiana Territory for over $30$ years.

  • New Proposal: As the US looked to build a transcontinental railroad, the organization of the remaining Louisiana Territory (Kansas and Nebraska) became a focal point.

  • The Conflict: Proposals to allow popular sovereignty in these areas (Kansas-Nebraska Act) directly contradicted the Missouri Compromise line ($36^{\circ} 30'$), as these territories were north of the line where slavery was supposed to be forever banned.

  • Result: This led to a period of violence known as "Bleeding Kansas" and a total breakdown of the peace established by the Missouri Compromise.
