Wonder Woman’s origin story comes straight out of feminist utopian fiction. In the nineteenth century, suffragists, following the work of anthropologists, believed that something like the Amazons of Greek myth had once existed, a matriarchy that predated the rise of patriarchy. “The period of woman’s supremacy lasted through many centuries,” Elizabeth Cady Stanton wrote in 1891. In the nineteen-tens, this idea became a staple of feminist thought. The word “feminism,” hardly ever used in the United States before 1910, was everywhere by 1913. The suffrage movement had been founded on a set of ideas about women’s supposed moral superiority. Feminism rested on the principle of equality. Suffrage was a single, elusive political goal. Feminism’s demand for equality was far broader. “All feminists are suffragists, but not all suffragists are feminists,” as one feminist explained. They shared an obsession with Amazons.
