This Chinese treatise on war was written by Sun Tzu in the 6th century B.C. Each one of the 13 chapters is devoted to a different aspect of warfare, making it the definitive work on military strategies and tactics of its time. Studied by generals from Napoleon to Rommel, it is still one of the most influential works on the subject and is required reading in most military academies around the world. Although it was meant to be a practical guide to warfare in the age of chariots, this seminal work on the philosophy of successful leadership is as applicable to contemporary business as it is to war, and has become increasingly popular among today's corporate and political leaders.
