Southern Democrats are members of the U.S. Democratic Party who reside in the American South.
In the 19th century, Southern Democrats comprised whites in the South who believed in Jacksonian democracy. In the 1850s they held that slavery was a good thing and promoted its expansion into the West. After Reconstruction ended in the late 1870s they controlled all the Southern states and disenfranchised the blacks (who were Republicans). The "Solid South" gave nearly all its electoral votes to Democrats in presidential elections. Republicans seldom were elected to office outside some mountain districts.
During the 1930s, as the New Deal began to move Democrats as a whole to the left in economic policy, Southern Democrats were mostly supportive, although by the late 1930s there was a growing conservative faction. Both factions supported Roosevelt's foreign policies. By 1948 the protection of segregation led Democrats in the Deep South to reject Truman and run a third party ticket of Dixiecrats in the 1948 election. After 1964, Southern Democrats lost major battles to the civil rights movement. Federal laws ended segregation and restrictions on black voters.

Rather I should die a thousand times, and see Old Glory trampled in the dirt never to rise again, than to see this beloved land of ours become degraded by race mongrels, a throwback to the blackest specimen from the wilds. - Democratic Senator Robert Byrd
