Election of 1852:
Party Divisions: The Whig Party faced internal disputes over slavery, nominating Winfield Scott, who avoided the issue, while the Democrats chose Franklin Pierce, a Northerner favorable to Southern interests due to his support of the Fugitive Slave Law. Pierce' overwhelming victory signaled the decline of the Whig Party.
Kansas-Nebraska Act (1854):
Legislative Background: Introduced by Senator Stephen A. Douglas to facilitate a transcontinental railroad and promote Western settlement, the act proposed dividing Nebraska Territory into Kansas and Nebraska, with slavery decided by popular sovereignty.
Impact: This effectively nullified the Missouri Compromise, leading to severe regional tensions as it opened new territories north of the 36°30′ line to slavery.
"Bleeding Kansas":
Violent Clashes: The application of popular sovereignty in Kansas led to violent conflicts between proslavery and antislavery settlers. The region earned the nickname "Bleeding Kansas" as both factions battled for control, significantly straining North-South relations.
Political and Social Turmoil: The violence showed the failure of popular sovereignty as a peaceful solution to the slavery question, with incidents like the sack of Lawrence by proslavery forces and the Pottawatomie Creek massacre by abolitionist John Brown escalating the crisis.
Caning of Senator Sumner (1856):
Congressional Violence: The tensions reached the U.S. Senate when Senator Charles Sumner, a staunch abolitionist, was brutally attacked by Congressman Preston Brooks after Sumner criticized proslavery positions. This incident horrified the North and was celebrated in the South, vividly illustrating the deepening national divide.
Birth of the Republican Party
Formation and Ideology: The Republican Party emerged in 1854 in response to the Kansas-Nebraska Act, primarily founded by anti-slavery ex-Whigs, Democrats, and Free-Soilers in Wisconsin. Its initial goal was to stop the spread of slavery into American territories.
Growth and Impact: As violence escalated in Kansas, the party grew rapidly, attracting abolitionists and becoming the major political force in the North. However, it was seen as a sectional party, contributing to increased tensions with the Southern states.
Election of 1856
Republican Debut: The Republican Party nominated John C. Frémont, focusing on the non-expansion of slavery and economic development. The Democrats chose James Buchanan. Despite losing, the party's strong showing in the North signaled its rising influence. James Buchanan was the next president.
Lecompton Constitution
Controversy and Outcome: In 1857, President Buchanan pushed for Kansas' admission as a slave state under the pro-slavery Lecompton Constitution, despite it lacking majority support in Kansas. The proposal was eventually rejected by Congress with opposition from both Republicans and some Democrats, illustrating the deep divisions over slavery.
Dred Scott v. Sandford (1857)
Supreme Court Decision: The court ruled that African Americans were not U.S. citizens and that Congress had no authority to prohibit slavery in the territories, effectively nullifying the Missouri Compromise. This decision outraged the North and was celebrated in the South, exacerbating sectional tensions.
Lincoln-Douglas Debates (1858)
Political Significance: These debates showed the national debate over slavery between Abraham Lincoln, the Republican candidate, and Senator Stephen Douglas, the Democratic incumbent. While Douglas supported popular sovereignty, Lincoln argued against the expansion of slavery on moral grounds. The debates boosted Lincoln's national profile, setting the stage for his presidential candidacy.
