About the Author

Sun Tzu was an ancient Chinese military general, strategist, and philosopher who is traditionally believed to have lived around 500 BCE. He is most famous as the reputed author of The Art of War, an influential treatise on military strategy that has shaped both Eastern and Western military thinking for over 2,500 years. While his exact historical details remain uncertain, Sun Tzu is revered as a legendary figure in Chinese and East Asian culture.

According to traditional accounts, Sun Tzu served as a general and advisor to King Helü of the state of Wu. His birth name was Sun Wu, and he was known by the courtesy name Changqing. The name “Sun Tzu” is actually an honorific title meaning “Master Sun.” Some modern scholars place the writing of The Art of War in the later Warring States period (475-221 BCE) based on its style and content, though debates about its exact origins continue.

Sun Tzu is credited with developing influential military doctrines and strategy, including the concept of asymmetrical warfare. The Art of War emphasizes the importance of positioning, planning, and understanding the enemy in achieving military success. Beyond purely military applications, Sun Tzu's principles have been widely applied to fields like business, sports, and politics in the modern era.
