This thesis examines George Eliot's The Mill on the Floss in the context of redefining Victorian middle-class gender roles. My point is to analyse how the characters (mainly Maggie and Tom Tulliver) pursue to fit into the gendered preconceptions and prejudices of the Victorian middle-class society, and how others intend to deviate from these embedded norms whether in a successful or unfortunate way. Maggie is not a typical heroine, she is portrayed as different and a distinctively non-conforming woman. She faces the complexities of not being able to create her own “feminine” personality because of the severe norms imposed upon her by Victorian society. Tom precisely bears the expected masculine traits and attitude, but he embodies an imaginative and shifting competence of whether he can accommodate to the conservative masculine Victorian role or not. All in all, the culturally constructed and generated “feminine” woman and “masculine” man indicate the narrow-minded and old-fashioned logic of the period that causes frustration for them to build up their well-formed individualities.
