'The Art of War' by Sun Tzu

The Art of War (Chinese: 孫子兵法; pinyin: Sūnzǐ bīngfǎ; 'Sun Tzu's Military Method') 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"), 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, has influenced both East Asian and Western military theory and thinking, and has found a variety of applications in myriad competitive non-military endeavors across the modern world including espionage, culture, politics, business, and sports.
