Military Theory & Strategic Treatises

• The Art of War (Sun Tzu) — foundational Chinese treatise on military strategy, traditionally attributed to the general Sun Tzu (Sunzi, “Master Sun”), said to have served King Helü of Wu in the late Spring and Autumn period (c. 5th century BCE); composed of thirteen chapters that open with “Laying Plans” (or “Detail Assessment and Planning”) and close with “The Use of Spies”; emphasizes winning without fighting, deception (“all warfare is based on deception”), terrain, and intelligence; one chapter builds an analogy from the small number of basic musical notes, colors, and flavors whose combinations are inexhaustible, with the “unorthodox and orthodox” mutually producing each other; the most famous early commentary is by the warlord Cao Cao during the Three Kingdoms era, one of many Han and Tang figures to annotate it; remains the most widely cited work of military theory in quizbowl, often paired with Carl von Clausewitz’s On War and Machiavelli’s The Art of War.
