The Art of War is an ancient Chinese military treatise dating from the 5th century BC. Attributed to the ancient Chinese military strategist Sun Tzu ("Master Sun", also spelled Sunzi) the text is composed of 13 chapters, each of which is devoted to one aspect of warfare. It is commonly thought of as a definitive work on military strategy and tactics. It was placed at the head of China's Seven Military Classics upon the collection's creation in 1080 by Emperor Shenzong of Song, and has long been the most influential strategy text in East Asia. It has had an influence on Eastern and Western military thinking, business tactics, legal strategy and beyond.

This edition is the unaltered, uncommented text as written by Sun Tzu in the translation of Lionel Giles, first published in 1910.
