Catharine Maria Sedgwick deserves to be better remembered today than she is both because of the quality of her own work as well as for her lasting influence on both the American domestic novel and the American historical novel. The daughter of a prominent Federalist politician, Sedgwick dedicated her life to her writing and was a staunch supporter of Federalist positions, although she shied from a politically activist role. This paper examines the life of this accomplished writing and analyzes two of her most important works, A Reminiscence of Federalism and Cacoethes Scribendi.
