Politics of the Southern United States (or Southern politics) refers to the political landscape of the Southern United States. Due to the region's unique cultural and historic heritage, the American South has been prominently involved in numerous political issues faced by the United States as a whole, including States' rights, slavery, the American Civil War, and the American Civil Rights Movement. Due to the South's conservative political leanings and political power, the South has seen the start of several political movements (such as George C. Wallace's American Independent Party) and the region plays a crucial role in Presidential politics (with the majority of the recent Presidents of the United States having come from the region).
