CEVAP:

By the early 19th century, the transition from the old feudal orders to the modern national era was complete insofar as weaponry, tactics, and military organization were concerned. In this era Napoleon introduced the mass citizen army based on conscription and revolutionized the conduct of war. While a number of industrial and agricultural innovations made it possible to extract ever larger numbers of manpower from the economic base without serious disruption, the size of Napoleonic armies was impossible to maintain unless the entire social and economic resources of the state were also mobilized for war. The age of modern war was beginning to dawn.
