A Streetcar Named Desire is a work of Southern Gothic literature, which is a subgenre of Gothic fiction set in the American South. It examines idiosyncrasies of the region as writers explore social and emotional issues. Southern Gothic literature is particularly characterized by an attention to local color and history, as well as the use of irony and the macabre to link Southern culture with the uncanny. It often features decayed or derelict settings of the Old South, deeply flawed or eccentric characters, and focuses on death and rebirth. The genre as a whole critiques the values of the South, often focusing on the aftermath of slavery and the legacy of the Civil War. Notable Southern Gothic authors include Flannery O’Connor, William Faulkner, and Tenessee Williams himself.
A Streetcar Named Desire is a play about death and regrowth. In Williams's New Orleans, the values and interests of the corrupt Old South are dying and being replaced by a new and different postwar mindset. Old-money aristocrats like Blanche and Stella Dubois, who would have been unlikely even to interact with members of the working class, are suddenly marrying into it and adopting its idioms and customs. Blanche herself embodies one of the foundational tropes of the Southern Gothic: the archetype of the "fallen woman." Once "pure," Blanche is now haunted by her past and unable to adapt to the harsh realities of her present. Practical, unsympathetic characters like Stanley—and, to some extent, Stella—represent the collapse of the romantic ideals Blanche clings to.
Williams’s depiction of New Orleans is full of contrasts: it is at once a lively, vivacious cultural hub and a rotting, bloated corpse of something that used to be beautiful. In this play—as in some of Williams’s other plays—the South is filled with a sense of loss and inevitability, mourning the beauty of eclipsed traditions while rejecting them in favor of more modern ideas.
