"Herland" by Charlotte Perkins Gilman is a feminist utopian novel written in 1915. Three male explorers discover an isolated society composed entirely of women who reproduce without men. What they find challenges every assumption they hold about gender, civilization, and human nature. As the men learn the language and customs of this all-female utopia—free of war, conflict, and domination—they must confront their own prejudices about what women should be, leading to revelations that test their understanding of society itself.
