Dong Zhongshu was a prominent Chinese philosopher, politician, and writer of the Western Han dynasty. He is traditionally associated with the promotion of Confucianism as the official state ideology of the Chinese imperial court, favouring Heaven worship over the tradition of cults celebrating the Five Elements (Wuxing). Active throughout the reigns of Emperor Jing of Han and Emperor Wu of Han, he served as an Erudite (boshi) of the Spring and Autumn Annals, and subsequently as Chancellor of the Kingdom of Jiangdu and the Kingdom of Jiaoxi. Dong presented his celebrated Three Strategies of Heaven and Man to Emperor Wu, articulating a comprehensive Confucian blueprint for imperial governance. In his later years he retired from public office to devote himself entirely to classical scholarship and writing; his surviving treatises were posthumously compiled into the compendium Luxuriant Dew of the Spring and Autumn Annals. Holding a paramount position in the history of Confucianism, Dong is widely esteemed as the foremost classicist of the Han era.
