Events in the late 1850s did nothing to quell the country’s sectional unrest, and compromise on the issue of slavery appeared impossible. Lincoln’s 1858 speeches during his debates with Douglas made the Republican Party’s position well known; Republicans opposed the extension of slavery and believed a Slave Power conspiracy sought to nationalize the institution. They quickly gained political momentum and took control of the House of Representatives in 1858. Southern leaders were divided on how to respond to Republican success. Southern extremists, known as “Fire-Eaters,” openly called for secession. Others, like Mississippi senator Jefferson Davis, put forward a more moderate approach by demanding constitutional protection of slavery.
