in what way does the levy in mass herald a new kind of warfare
Levée en masse Historically, the levée en masse heralded the age of the people's war and displaced restricted forms of warfare, such as the cabinet wars (1715–1792), when armies of professional soldiers fought without the general participation of the population.
English Civil War The English Civil War (1642–1651) was a series of armed conflicts and political machinations between Parliamentarians ("Roundheads") and Royalists ("Cavaliers") over, principally, the manner of England's government. The first (1642–1646) and second (1648–1649) wars pitted the supporters of King Charles I against the supporters of the Long Parliament, while the third (1649–1651) saw fighting between supporters of King Charles II and supporters of the Rump Parliament. The war ended with the Parliamentarian victory at the Battle of Worcester on 3 September 1651.
