“Let your plans be as dark and impenetrable as night, and when you move, fall like a thunderbolt.”

Sun Tzu (400 BCE to 301 BCE)

Sunzi, Wade-Giles romanisation Sun-tzu, also spelled Sun Tzu, personal name Sun Wu, (flourished 5th century BC), reputed author of the Chinese classic Bingfa (The Art of War), the earliest known treatise on war and military science.

Sunzi, a military strategist and general who served the state of Wu near the end of the Spring and Autumn Period (770–476 BC), is traditionally considered the author of The Art of War, but the work is more likely to have been written early in the Warring States period (475–221 BC), at a time when China was divided into six or seven states that often resorted to war with each other in their struggles for supremacy.
