This book explores Lucy Hutchinson’s historical writings and more particularly the Memoirs of the Life of Colonel Hutchinson, which, although composed between 1664 and 1667, were first published in 1806. The Memoirs were a best-seller in the nineteenth century, but largely fell into oblivion in the twentieth century. They were eventually rediscovered in the late 1980s by historians and literary scholars interested in women’s writing, the emerging culture of republicanism and dissent. By approaching the Memoirs through the prism of history and form, this book challenges the widely-held assumption that early modern women did not – and could not – write the history of wars, a field that was supposedly gendered as masculine. On the contrary, it shows that Lucy Hutchinson, a reader of ancient history and an outstanding Latinist, was a historian of the English Revolution, to be ranked alongside Richard Baxter, Edmund Ludlow, and Edward Hyde.
