The Art of War' is an ancient Chinese military treatise written by Sun Tzu, a high-ranking military general, strategist and tactician. The text is composed of 13 chapters, each of which is devoted to one aspect of warfare. It is commonly known to be the definitive work on military strategy and tactics of its time. It has been the most famous and influential of China's Seven Military Classics, and for the last two thousand years it remained the most important military treatise in Asia, where even the common people knew it by name.

Sun Tzu believed war to be an essential wrongdoing that must be got rid of whenever it can be. The war should be fought fleetingly to reduce economic decline. Sun Tzu harped on the significance of placement in military tactics. The planning to position an army must be dependent on the stipulations in the physical surroundings and the subjective thoughts of various militants in those conditions. He believed that strategy cannot be considered as planning with respect to glancing through a previously decided list. It is better represented by the fact that it needs speedy and suitable reactions to altering situations. Planning gives results in restrained surroundings. But in case of an altering environment, similar plans come in each other's ways and give rise to undesired outcomes. It has had an influence on Eastern and Western military thinking, business tactics, legal strategy and beyond.
