Sun Tzu (544-496 BC) is often considered as the father of Eastern military strategy and greatly influenced Chinese, Japanese, Korean and Vietnamese historical and modern war tactics. "The Art of War" by Sun Tzu grew in popularity and saw practical use in Western society as well. It continues to influence many competitive endeavors in Asia, Europe, and America including culture, politics, and business, as well as modern warfare. The Eastern military strategy differs from the Western by focusing more on asymmetric warfare and deception. Chanakya's Arthashastra has been important strategic and political compendium in Indian and asian history as well.
