Causes and Escalation Map: Towards the American Civil War

The Missouri Compromise of $1820$

• Historical Context of the Early $1800s$: During the initial decades of the $19^{th}$ century, the United States government maintained a delicate and strategic balance within Congress between states that permitted slavery (slave states) and states that prohibited it (free states).

• The Missouri Statehood Conflict: The equilibrium of political power was challenged when Missouri applied to join the Union as a slave state. This request ignited intense and volatile arguments within Congress, as it threatened to give pro-slavery interests a majority.

• Terms of the $1820$ Compromise: To resolve the deadlock, a multi-part agreement was reached:

  • Missouri's Admission: Missouri was officially admitted to the United States as ma slave state.

  • Maine's Admission: To maintain the Congressional balance, Maine was separated from Massachusetts and admitted as a free state.

  • The $36^{th}$ Parallel (The Geometric Divide): A geographical boundary was established at the latitude line of $36^{\circ}30'$ North. Under this rule, all future states formed from the Louisiana Purchase territory located north of this line would be designated as free states, while those south of the line would be designated as slave states.

Legislative Stalemates and Congressional Conflict

• The "Gag" Rule ($1836$): In an effort to avoid the escalating tensions over the institution of slavery, Congress passed the "Gag" Rule in $1836$. This procedural rule effectively silenced all formal debate, petitions, or discussions regarding slavery within the halls of Congress for a duration of $10$ years.

• The Wilmot Proviso: Introduced during the Mexican-American War, this legislative proposal suggested that any land or territory acquired as a result of the war must be designated as free territory, where slavery would be strictly prohibited. Despite its support in the House, the Proviso was ultimately rejected in the Senate, highlighting the deep sectional divide.

• The Beating of Charles Sumner ($1856$): Political discourse turned into physical violence on the floor of the Senate in $1856$. Congressman Preston Brooks, a pro-slavery advocate, brutally attacked Senator Charles Sumner with a cane. The assault was a direct retaliation for a speech Sumner delivered in which he criticized and spoke out vehemently against slave owners.

The Compromise of $1850$

• The California Statehood Crisis: Arguments erupted in Congress once again when California sought admission to the Union as a free state. Because California’s admission would disrupt the balance of power, a complex legislative package was required to appease both Northern and Southern interests.

• Key Provisions of the $1850$ Compromise:

  • Statehood and Sovereignty: California was admitted as a free state. Conversely, the territories of New Mexico and Utah were organized without specific restrictions on slavery, allowing the actual voters in those regions to decide the issue for themselves through popular sovereignty.

  • District of Columbia: The compromise officially banned the slave trade within Washington D.C., though slavery itself remained legal in the capital.

  • The Fugitive Slave Act: This was a highly controversial federal law that mandated that citizens in Northern free states assist in the capture and return of runaway slaves to their Southern owners. It placed the power of the federal government behind the enforcement of slaveholding rights across state lines.

The Kansas-Nebraska Act and "Bleeding Kansas"

• Abolition of the Missouri Compromise: The Kansas-Nebraska Act fundamentally altered American territorial policy by abolishing the long-standing Missouri Compromise. It discarded the $36^{th}$ parallel as the deciding factor for slavery's expansion.

• Popular Sovereignty in the Territories: The Act mandated that voters in new territories would determine the legal status of slavery. This shift led to a desperate rush of both pro-slavery and anti-slavery supporters into the region to influence the outcome.

• "Bleeding Kansas": The competition for the soul of the territory resulted in the breakout of violent, bloody disputes between abolitionists and pro-slavery supporters. This period of localized civil war became known nationally as "Bleeding Kansas."

• The Role of John Brown: Abolitionist John Brown became a prominent figure during this era of violence. He led a group of anti-slavery fighters and oversaw the killing of $5$ pro-slavery individuals in Kansas, further polarizing the nation.

Abolitionist Influence and Judicial Impact

• Literary Influence - "Uncle Tom's Cabin": Published in $1852$ by author Harriet Beecher Stowe, this novel was written with the explicit intent of exposing Northerners to the brutal reality and moral horrors of slavery. The book had a profound impact on public sentiment in the North.

• The Dred Scott Decision ($1857$): Dred Scott, an enslaved man, attempted to sue for his freedom before the U.S. Supreme Court, arguing that his residency in free territories made him a free man. The Supreme Court ruled against him, declaring that as a Black man, he was not a citizen and therefore had no legal rights to sue in federal court.

• Southern Anxiety and Resistance: Internal resistance to slavery was exemplified by Nat Turner's Rebellion and similar slave revolts. These events caused Southern slave owners to become increasingly anxious and defensive regarding their continued ability to maintain control over the institution of slavery within the United States.
