The Victorian novel emerged as a new literary genre in the 1800s. Novels were first published in installments in periodicals, which made them affordable and accessible to masses. Victorian novels portrayed realistic depictions of contemporary society and examined characters' inner lives. Popular genres included novels of manners, social problem novels, and sensation novels. Throughout the Victorian period, novels evolved from didactic works that aimed to instruct readers, to more realistic and critical works that questioned societal norms and portrayed characters as alienated and powerless. Realism and naturalism became influential styles as novels adopted a more objective, scientific approach to literature.
