Guanzi (text) in the context of "Legalism (Chinese philosophy)"

The Lower Paleolithic era on the Korean Peninsula and in Manchuria began roughly half a million years ago. The earliest known Korean pottery dates to around 8000 BC and the Neolithic period began thereafter, followed by the Bronze Age by 2000 BC, and the Iron Age around 700 BC. The Paleolithic people are likely not the direct ancestors of the present Korean people, but their direct ancestors are thought to be the Neolithic People of about 2000 BC.

According to the mythic account recounted in the Samguk yusa (1281), the Gojoseon kingdom was founded in northern Korea and southern Manchuria in 2333 BC. The first written historical record on Gojoseon can be found from the text Guanzi. The Jin state was formed in southern Korea by the 3rd century BC. In the late 2nd century BC, Gojoseon eventually fell to the Han dynasty of China, which led to succeeding warring states, the Proto–Three Kingdoms period.

Guan Zhong (Chinese: 管仲; Wade–Giles: Kuan Chung; c. 720–645 BC) was a Chinese philosopher and politician. He served as chancellor and was a reformer of the State of Qi during the Spring and Autumn period of Chinese history. His given name was Yiwu (Chinese: 夷吾; pinyin: Yíwú). Zhong was his courtesy name. He is mainly remembered for his reforms as chancellor under Duke Huan of Qi, as well as his friendship with his colleague Bao Shuya, though his reputation remained controversial among the Confucians, as detailed in the appraisal section.

Through Guan Zhong's reforms and skilful diplomacy Qi became the most powerful of the feudal states and Duke Huan became the first of the Five Hegemons. Though knowledge of his reforms is limited, in particular he instituted a famous fiscal policy known as "balancing the light and the heavy", associated with salt and iron monopolies. Otherwise a diverse work, the Guanzi compilation making use of his name makes similar such recommendations.
