The Hundred Schools of Thought were philosophies and schools that flourished during the late Spring and Autumn period and Warring States period. The term was not used to describe these different philosophies until Confucianism, Mohism, and Legalism were created. The era in which they flourished was one of turbulence in China, fraught with chaos and mass militarization, but where Chinese philosophy was developed and patronized by competing bureaucracies. This phenomenon has been called the Contention of a Hundred Schools of Thought.
