The Art of War is the world's oldest military treatise, composed in ancient China by the strategist Sun Tzu during the Spring and Autumn period. In thirteen concise chapters, Sun Tzu distils the essence of military strategy into timeless maxims on planning, deception, adaptability, and the conservation of strength. Far beyond warfare, its insights into leadership, competition, and the psychology of conflict have influenced generals, statesmen, and thinkers across twenty-five centuries. This edition presents Lionel Giles's landmark 1910 English translation.
