In December 1860, the Crittenden Compromise was proposed to re-establish the Missouri Compromise line, by constitutionally banning slavery in territories to the north of it, while permitting it to the south. The Compromise would likely have prevented secession, but Lincoln and the Republicans rejected it. Lincoln stated that any compromise that would extend slavery would bring down the Union. A February peace conference met in Washington, proposing a solution similar to the Compromise; it was rejected by Congress. The Republicans proposed the Corwin Amendment, an alternative, not to interfere with slavery where it existed, but the South regarded it as insufficient. The remaining eight slave states rejected pleas to join the Confederacy, following a no-vote in Virginia's First Secessionist Convention on April 4.
