The American Civil War begins
Secession after Lincoln’s election turns the constitutional crisis over slavery and union into full war.
The conflict remakes the American state, the presidency, and the constitutional meaning of citizenship and federal power.
The beginning of the Civil War marks the collapse of decades of attempted compromise over slavery, sovereignty, and the meaning of the Union. By 1861 the central political question was no longer whether sectional conflict could be managed procedurally. It was whether the republic contained one sovereign people or a loose compact from which slaveholding states could withdraw when national elections threatened their social order.
The war also transforms the scale of American governance. Mobilization, finance, emancipation policy, conscription, and military command all increase the reach of the national state. That expansion matters because it creates the institutional conditions for Reconstruction and permanently changes expectations about federal authority.
