The Yellow Wallpaper is a short story by Charlotte Perkins Gilman that delves into the psychological effects of confinement and the oppression of women in the late 19th century. The protagonist, a woman suffering from postpartum depression, is confined to a room with yellow wallpaper by her physician husband. As she spends more time in the room, she becomes obsessed with the wallpaper, seeing disturbing patterns and hallucinations. The story is a powerful critique of the patriarchal society and the treatment of women as fragile and hysterical. It explores themes of confinement, madness, and the struggle for self-expression.
