Abstract
Two main authors had an impact on strategy: Sun Tzu who, 500 years BC, was the author of a treaty, The Art of War, in which he presents principles founded on the knowledge of pre-battle context. The second one was the Prussian General Carl von Clausewitz, who will be the main initiator of the modern thoughts in the studying of conflicts with the release of his book Vom Kriege (On War). It will be the first treaty which originality consists in considering war not exclusively in a destruction purpose, but as a political act consisting in submitting an opponent to the conditions we want to impose to him in order to exploit the positive consequences.
