Harper Lee's classic novel To Kill a Mockingbird falls under several genres. To Kill a Mockingbird falls under the genre of Southern Gothic, which focuses on grotesque themes and includes dark, suspenseful elements. The novel also includes inexplicable evil in the form of Bob Ewell and the destructive racist southern culture, which is rooted in slavery, violence, and prejudice. Supernatural elements are also referenced in the story in the form of literal and figurative ghosts.
To Kill a Mockingbird also falls under the genre of bildungsroman because it traces Scout's moral development and maturation throughout her childhood in Maycomb, Alabama. At the beginning of the story, Scout is a naive, innocent girl, who eventually gains perspective and insight into her racist community after witnessing Tom Robinson become a victim of racial injustice.
The novel also falls under the genre of courtroom drama when Atticus valiantly defends his client, Tom Robinson, in front of a racist jury. Since the events and characters are made up, To Kill a Mockingbird falls under the larger genre of long fiction.
