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. The book was first translated into French in 1772 by the Jesuit Jean Joseph Marie Amiot and a partial translation into English was attempted by British officer Everard Ferguson Calthrop in 1905. The first annotated English translation was completed and published by Lionel Giles in 1910. This present edition comes from Lionel Giles's translation.
