Sun Tzu's The Art of War is an ancient treatise on military strategy dating back to late-sixth century B.C. China. Its 13 chapters provide enumerated reflections and lessons on practical tactics to give readers an edge over their adversaries. While The Art of War has served military figures throughout history, from Napolean to General Douglas MacArthur, in the 20th century it gained notoriety outside of actual combat. It is now considered one of the most inspirational and informative texts for business management throughout the world.
