This thesis explores We Two Together, the unique dual autobiography of the reformers Margaret and James Cousins. It places this rich text in the context of the first half of the twentieth century and demonstrates its value as a source for Irish, Indian, gender, and global history. It investigates how the Cousinses represent their efforts to create and maintain a companionate marriage over a lifetime, depict their work as activists for women’s suffrage, Indian nationalism, educational reform, and other causes, and recount the impact of cross-cultural encounters on their cosmopolitan lives. We Two Together provides insight into the lives of two extraordinary individuals as they witnessed and participated in several key social and political movements in Ireland and India. In bringing attention to this book, I hope that other historians will make use of it and that librarians will preserve the rare copies in their possession.
