The American Civil War (1861–1865) was not the result of a single disagreement but rather a complex web of social, political, and economic tensions that had been building for decades—centered above all on the institution of slavery and the contested balance of power between federal and state governments. By the early 1800s, the Northern and Southern states had evolved into two fundamentally different economies: the North embraced industrialization, wage labor, and free-soil farming, while the South depended on cash crops—especially cotton—produced by enslaved African Americans on large plantations.

The Democratic Party split along regional lines, and the new Republican Party, explicitly opposed to the expansion of slavery, nominated Abraham Lincoln in 1860. Lincoln’s election, without a single Southern electoral vote, convinced many white
