In "To Kill a Mockingbird," Aunt Alexandra, Atticus Finch's older sister, comes to stay with Atticus and the children so that Scout can have a "feminine influence." She takes over as the female head of the household and thinks that the presence of Calpurnia, the Finch's long-time maid, is no longer necessary.
According to SparkNotes.com, Aunt Alexandra is a proper Southern woman who takes great pride in her family's history. She believes that Scout and Jem should be raised properly in a more respectable manner and is particularly shocked by Scout's tomboy behavior. Her rigid rules and inflexible attitude clash with the way Calpurnia has been running the household, and Aunt Alexandra thinks her relationship with the children is inappropriate. For example, Aunt Alexandra does not think it is proper for Scout to attend the "black" church with Calpurnia and forbids her to return. Clearly, Aunt Alexandra is not as progressive as Atticus when it comes to racial issues. She then tries to convince Atticus to get rid of Calpurnia, claiming that they no longer need her since she is Aunt Alexandra is there now, but Atticus refuses. Aunt Alexandra does not realize how important Calpurnia is to the family, so when Atticus stands up to her, she backs down.
