A subgenre of Gothic fiction unique to American literature that takes place exclusively in the American South. Common themes in Southern Gothic literature include deeply flawed, disturbing or disorienting characters, decayed or derelict settings,grotesque situations, and other sinister events relating to or coming from poverty, alienation, racism, crime, and violence.[1] It is unlike its parent genre in that it uses these tools not solely for the sake of suspense, but to explore social issues and reveal the cultural character of the American South, with the Gothic elements taking place in a magic realist context rather than a strictly fantastical one.
