Key Points on Pre-Civil War Political Climate

Significant during James Buchanan's presidency, which coincided with deep national division over slavery.
Buchanan epitomized the old political order; had extensive political experience but struggled to unite a fracturing nation.

Supreme Court case announced in March 1857, just two days after Buchanan's inauguration, further inflaming sectional tensions.
Dred Scott, an enslaved man, sued for his freedom after residing with his owner in free territories and states.
Ruling stated only white persons could be U.S. citizens; consequently, Black individuals, whether free or enslaved, could not sue in federal court.
Declared Congress lacked power to bar slavery from territories (invalidating the Missouri Compromise and popular sovereignty principles);
invalidated the core Republican platform against slavery's expansion.
Initiated national debate on Black citizenship and governmental power over slavery in the territories.

Stephen Douglas faced opposition from Abraham Lincoln in the Illinois Senate race of 1858.
Lincoln's speeches (e.g., "House Divided" speech) combined abolitionist fervor with constitutional respect, arguing that the nation could not long endure half slave and half free.
Campaign centered on differing definitions of freedom: Lincoln opposed the expansion of slavery into new territories, viewing it as a moral wrong;
Douglas favored local self-determination through popular sovereignty, allowing residents of a territory to decide on slavery.
Lincoln received no support for racial equality or intermarriage but asserted universal rights for all humans, including the right to the fruits of one's labor.

Raid on federal arsenal by abolitionist John Brown and his followers on October 16, 1859, with the goal of arming enslaved people for a mass uprising.
Sparked sectional tensions; Brown's capture and execution made him a martyr in the North and a symbol of northern aggression in the South.
His message of violent resistance against slavery resonated widely among some abolitionists, while others condemned his methods.

Growing sentiment among Southerners favoring secession to form a distinct slaveholding empire, fearing federal interference with slavery.
Ostend Manifesto (1854) publicly announced a desire to acquire Cuba, largely to extend slave territory and power.
Southern leaders began to openly discuss secession as a viable option, articulating a distinct Southern identity based on the institution of slavery.

Democratic Party split over slavery: Northern Democrats nominated Stephen Douglas, advocating popular sovereignty; Southern Democrats nominated John C. Breckinridge, demanding federal protection for slavery in the territories.
Republicans nominated Abraham Lincoln, explicitly opposing the Dred Scott decision and advocating for economic reform like a protective tariff and free homesteads.
A fourth party, the Constitutional Union Party, nominated John Bell, seeking to preserve the Union without addressing slavery.
Lincoln won predominantly northern votes, securing a clear electoral college victory despite not appearing on the ballot in ten Southern states, while Southern candidates faced poor sectional support, highlighting the deep regional divide.

South Carolina was the first to secede on December 20, 1860, immediately following Lincoln's election, emphasizing that the federal government was no longer a "slave-holding confederacy" and stressing slavery's importance to their society.
Buchanan's lame-duck government was perceived as ineffective in addressing secession, not believing it had the constitutional power to compel states to remain in the Union.
Crittenden's compromise proposal, which aimed to extend the Missouri Compromise line to the Pacific and guarantee slavery in territories south of it, was ultimately rejected by Lincoln and most Republicans.
By February 1861, seven Southern states (SC, MS, FL, AL, GA, LA, TX) formed the Confederate States of America and elected Jefferson Davis as president, explicitly embedding the protection of slavery in their constitution.
