The Union in Peril: Lincoln and the Secession Crisis 1860-April 1861 – Ian Iverson

March 17, 2026

The election of Abraham Lincoln to the presidency in November 1860 precipitated an unprecedented national emergency. The secession of seven southern states between December and February triggered a flurry of efforts in Washington to peacefully reunite the country, even as Secessionist forces seized U.S. arsenals and menaced federal troops occupying forts in South Carolina and Florida. Within the halls of lame-duck Congress, advocates of compromise grappled with hardliners to draft legislation and constitutional amendments that would diffuse the crisis. In this lecture, Dr. Ian Iverson will outline the difficult choices facing President-elect Lincoln, detail the political machinations that stymied the so-called “Crittenden Compromise,” and walk through the chain of events that culminated in the Confederate bombardment of Fort Sumter on April 12, 1861.
