The southern Democrats were the party of racism and anti-black terrorism. They were conservative, anti-negro, aristocratic and anti-democratic. They were opposed by the southern Republican party, which was a working-class party that attracted all african-americans and 10-40% of the white vote depending on the southern state. Once Reconstruction was abandoned, the aristocratic whites in the KKK assassinated all of the african-american leaders and terrorized the rest into submission, thus ending the southern experiment in democracy for a century. The southern Democratic party was the party of white supremacy, and there was no other party. This ended in the 1960s, when leading racists in the southern Dems, realizing the distance between themselves and the national party, first founded their own explicitly southern party (the Dixiecrats) and then finally relented and joined the GOP, which was their natural home.
