The English Civil War was not simply a conflict between two opposing, unstable, complicated alliances of various factions, but a war of words. Supporters of the King and allies of Parliament and the New Model Army clashed over ideals, ideas, and concepts as they each sought to impose their understanding of history and visions of the future, realizing that victory could only be secured by establishing a political and cultural language that would guide and direct those who used it. Accordingly, the Civil War witnessed vociferous arguments over many key English words central to life and thought in the seventeenth century, and often up to the present day. Words at War seeks to bring together scholars of literature, history, religion, and philosophy to analyse the ways in which key terms were deployed and debated in the Civil War and Commonwealth. In doing so it refocuses attention on ideas and concepts that shaped the modern world well beyond the bloody conflict on the battlefield.
