This chapter discusses the writings during the English Civil Wars of Margaret Cavendish, who accompanied Henrietta Maria in exile to France. Like Christine de Pizan, whose writings she may have known, she produced an extensive oeuvre in various genres. She registers her experience of civil war in her orations, essays, poetry, and plays, written during the 1650s and published after the Restoration in 1660. The Life of William Cavendish (1667), widely read by political and military historians of the English Civil Wars, corresponds closely to Christine’s life of Charles V. Despite her husband’s role as Charles I’s general and Charles II’s governor, Cavendish stakes out a position that might be characterized as “ambiguous royalism”; her position in fact tracks closely the aristocratic anti-monarchism of the frondeuses, active during her sojourn in France. By analyzing the shortcomings of Charles I as king and military leader, she counsels Charles II to avoid the mistakes his father made.
