The Alabama extremist William Lowndes Yancey's demand for a federal slave code for the territories split the Democratic Party between North and South, which made the election of Lincoln possible. Yancey tried to make his demand for a slave code moderate enough to get Southern support and yet extreme enough to enrage Northerners and split the party. He demanded that the party support a slave code for the territories if later necessary, so that the demand would be conditional enough to win Southern support. His tactic worked, and lower South delegates left the Democratic Convention at Institute Hall in Charleston, South Carolina, and walked over to Military Hall. The South Carolina extremist Robert Barnwell Rhett hoped that the lower South would completely break with the Northern Democrats and attend a separate convention at Richmond, Virginia, but lower South delegates gave the national Democrats one last chance at unification by going to the convention at Baltimore, Maryland, before the split became permanent. The result was that John C. Breckinridge became the candidate of the Southern Democrats, and Stephen Douglas became the candidate of the Northern Democrats.
