The Southern Democratic Party refers to the faction of the Democratic Party that emerged in the southern United States, particularly during the late 19th and early 20th centuries. This group was characterized by its support for states' rights, segregation, and agricultural interests, often opposing the more progressive elements of the national party. Historically, the Southern Democrats played a significant role in shaping regional politics, especially during the Jim Crow era, when laws enforced racial segregation. Over time, the party's influence waned as national Democratic policies shifted towards civil rights and social justice, leading to a realignment of political affiliations in the South.
