Carl Philipp Gottlieb von Clausewitz was a Prussian soldier, military historian and military theorist who's Vom Kriege (On War) has influenced military leaders for two centuries. On War is an intricate investigation of Clausewitz's observations based on his own experience in the Wars of the French Revolution and the Napoleonic Wars and on considerable historical research into war. It was shaped not only by military and political considerations but by Clausewitz's strong interests in art, science, and education. In On War von Clausewitz examines moral and psychological aspects of warfare, stressing the necessity of courage, audacity, and self-sacrifice, as well as the importance of morale and public opinion. He emphasizes the need of strategy as an evolving plan, a concept adaptable to modern strategists in fields beyond military science.
