Sun Tzu was a Chinese general, military strategist, and philosopher credited as the author of 'The Art of War.' This ancient treatise consists of 13 chapters, each devoted to one aspect of warfare, emphasizing the importance of intelligence, speed, and psychological warfare over brute force. One of his most famous principles is that 'the supreme art of war is to subdue the enemy without fighting.' His teachings have transcended the battlefield, influencing modern business strategy, sports coaching, and political diplomacy. Despite debates among historians about whether Sun Tzu was a single individual or a composite of several strategists, his work remains the most influential strategy document in history.
