Legalism (Chinese philosophy)Fajia, often termed Legalism, is one of six classical schools of thought in Chinese philosophy. Literally meaning (administrative) methods/standards (Fa; 法) "house" or "school" (Jia), the Fa "school" represents several branches of what Feng Youlan called "men of methods", in the West often termed "realist" statesmen, who played foundational roles in the construction of the bureaucratic Chinese empire. The earliest persona of the Fajia may be considered Guan Zhong (720–645 BCE), but Chinese historians commonly regard Li Kui (455–395 BCE) as the first or "founding" "Legalist" philosopher.
Qin (state)Qin () was an ancient Chinese state during the Zhou dynasty. Traditionally dated to 897 BC, it took its origin in a reconquest of western lands previously lost to the Rong; its position at the western edge of Chinese civilization permitted expansion and development that was unavailable to its rivals in the North China Plain. Following extensive "Legalist" reform in the fourth century BC, Qin emerged as one of the dominant powers of the Seven Warring States and unified the seven states of China in 221 BC under Qin Shi Huang.
Warring States periodThe Warring States period () was an era in ancient Chinese history characterized by warfare, as well as bureaucratic and military reforms and consolidation. It followed the Spring and Autumn period and concluded with the Qin wars of conquest that saw the annexation of all other contender states, which ultimately led to the Qin state's victory in 221 BC as the first unified Chinese empire, under the Qin dynasty. Although different scholars point toward different dates ranging from 481 BC to 403 BC as the true beginning of the Warring States, Sima Qian's choice of 475 BC is the most often cited.
Chinese classicsChinese classic texts or canonical texts () or simply dianji (典籍) refers to the Chinese texts which originated before the imperial unification by the Qin dynasty in 221 BC, particularly the "Four Books and Five Classics" of the Neo-Confucian tradition, themselves a customary abridgment of the "Thirteen Classics". All of these pre-Qin texts were written in classical Chinese. All three canons are collectively known as the classics (t , s , jīng, lit. "warp").
