Dong Zhongshu (Chinese: 董仲舒; pinyin: Dǒng Zhòngshū; Wade–Giles: Tung Chung-shu, 179–104 BC) was a Han Dynasty Chinese scholar. He is traditionally associated with the promotion of Confucianism as the official ideology of the Chinese imperial state.
Dong was born in modern Hengshui, Hebei in 179 BCE. He entered the imperial service during the reign of Emperor Jing of Han and rose to high office under Emperor Wu of Han. His relationship with the emperor was uneasy though. At one point he was thrown into prison and nearly executed for writings that were considered seditious, and he may have cosmologically predicted the overthrow of the Han Dynasty and its replacement by a Confucian sage, the first appearance of a theme that would later sweep Wang Mang to the imperial throne.
Dong Zhongshu's thought integrated Yin Yang cosmology into a Confucian ethical framework. He emphasised the importance of the Spring and Autumn Annals as a source for both political and metaphysical ideas, following the tradition of the Gongyang Commentary in seeking hidden meanings from its text. He is also considered the originator of the doctrine of Interactions Between Heaven and Mankind, which lays down rules for deciding the legitimacy of a monarch as well as providing a set of checks and balances for a reigning monarch.
There are two works that are attributed to Dong Zhongshu, one of which is the Ju Xianliang Duice in three chapters, preserved under the Book of Han. Another of his major works that has survived to the present is the Luxuriant Dew of the Spring and Autumn Annals in 82 chapters. The Luxuriant Dew of the Spring and Autumn Annals bears many marks of multiple authorship. Whether the work was written by Dong himself has been called into question by several scholars including Zhu Xi, Cheng Yanzuo, Dai Junren, Keimatsu Mitsuo, and Tanaka Masami. Scholars now reject as later additions all the passages that discuss five elements theory, and much of the rest of the work is questionable as well. It seems safest to regard it as a collection of unrelated or loosely related chapters and shorter works, which could be subdivided into five categories. Most are more or less connected to the Gongyang Commentary and its school and written by a number of different persons at different times throughout the Han Dynasty.
Other important sources for Dong Zhongshu's life and thought include his poem The Scholar's Frustration, his biography included in the Book of Han, his Yin Yang and stimulus-response theorizing noted at various places in the Book of Han "Treatise on the Five Elements," and the fragments of his legal discussions.
