Which of the following formed the Democratic party of the South?

In the 19th century, Southern Democrats were people in the South who believed in Jacksonian democracy. In the 19th century, they defended slavery in the United States, and promoted its expansion into the West against northern Free Soil opposition. The United States presidential election of 1860 formalized the split in the Democratic Party and brought about the American Civil War. Stephen Douglas was the candidate for the Northern Democratic Party, and John C. Breckinridge represented the Southern Democratic Party. Abraham Lincoln, who opposed slavery, was the Republican Party candidate.[1] After Reconstruction ended in the late 1870s so-called redeemers controlled all the Southern states and disenfranchised blacks. The "Solid South" gave nearly all its electoral votes to the Democrats in presidential elections. Republicans seldom were elected to office outside some Appalachian mountain districts and a few heavily German-American counties of Texas.
