Sun Tzu was an ancient Chinese military strategist traditionally believed to have lived during the late Spring and Autumn period, sometime between the sixth and fifth centuries BCE. Although the details of his life remain uncertain, he has long been associated with the state of Wu and is credited with composing The Art of War, a concise manual on strategy, command, intelligence, and the management of conflict.His work emphasizes preparation, deception, flexibility, knowledge of terrain, disciplined leadership, and the importance of understanding both oneself and one's opponent. The Art of War became a foundational text of Chinese military thought and later gained worldwide influence in politics, diplomacy, business, sports, and other competitive fields.
