Sun Tzu (;traditional Chinese: 孫子; simplified Chinese: 孙子; pinyin: Sūnzǐ) may have been a Chinese military general, strategist, philosopher, and writer who lived during the Eastern Zhou period (771–256 BC). Sun Tzu is traditionally credited as the author of The Art of War, a Classical Chinese text on military strategy from the Warring States period, though the earliest parts of the work probably date to at least a century after his purported death.
