Title: Sun Tzu
Content:   The Art of War is traditionally ascribed to Sun Tzu. It presents a philosophy of war for managing conflicts and winning battles. It is accepted as a masterpiece on strategy and has been frequently cited and referred to by generals and theorists since it was first published, translated, and distributed internationally. There are numerous theories concerning when the text was completed and concerning the identity of the author or authors, but archeological recoveries show The Art of War had taken roughly its current form by at least the early Han period. Because it is impossible to prove definitively when the Art of War was completed before this date, the differing theories concerning 
Title: The Art of War
Content:  The Art of War is an ancient Chinese military treatise dating from the Late Spring and Autumn Period (roughly 5th century BC). The work, which is attributed to the ancient Chinese military strategist Sun Tzu ("Master Sun", also spelled Sunzi), is composed of 13 chapters. Each one is devoted to a different set of skills (or "art") related to warfare and how it applies to military strategy and tactics. For almost 1,500 years it was the lead text in an anthology that was formalized as the Seven Military Classics by Emperor Shenzong of Song in 1080. The Art of War remains the most influential strategy text in East Asian warfare and has influenced both Far Eastern and Western military thinking, business tactics, legal strategy, lifestyles and beyond. The book contains a detailed explanation and analysis of the 5th-century Chinese military,

This view is still widely held in China. The strategist, poet, and warlord Cao Cao in the early 3rd century AD authored the earliest known commentary to the Art of War. Cao's preface makes clear that he edited the text and removed certain passages, but the extent of his changes were unclear historically. The Art of War appears throughout the bibliographical catalogs of the Chinese dynastic histories, but listings of its divisions and size varied widely.
Title: The Art of War
Content:  The Art of War is traditionally attributed to an ancient Chinese military general known as Sun Tzu (now romanized "Sunzi"), meaning "Master Sun". Sun Tzu was traditionally said to have lived in the 6th century BC, but The Art of War earliest parts probably date to at least 100 years later. Sima Qian's Records of the Grand Historian, the first of China's 24 dynastic histories, records an early Chinese tradition that a text on military matters was written by one "Sun Wu" (孫武) from the State of Qi, and that this text had been read and studied by King Helü of Wu ((r. 514 BC – 495 BC)). This text was traditionally identified with the received Master Sun's Art of War. The conventional view was that Sun Wu was a military theorist from the end

The first traditional view is that it was written in 512 BC by the historical Sun Wu, active in the last years of the Spring and Autumn period (c. 722–481 BC). A second view, held by scholars such as Samuel Griffith, places The Art of War during the middle to late Warring States period (c. 481–221 BC). Finally, a third school claims that the slips were published in the last half of the 5th century BC; this is based on how its adherents interpret the bamboo slips discovered at Yinque Shan in 1972 AD.
