Domestic tragedy
In English drama, a domestic tragedy is a tragedy in which the tragic protagonists are ordinary middle-class or lower-class individuals. This subgenre contrasts with classical and Neoclassical tragedy, in which the protagonists are of kingly or aristocratic rank and their downfall is an affair of state as well as a personal matter.
