A dominant Han dynasty school of Confucianism that studied Classics written in the contemporary clerical script of that era. It was established as official state doctrine under Emperor Wu, often emphasizing the political and social reforms found in the 春秋公羊传 chūn​qiū​gōng​yáng​zhuàn. The school saw a major revival in the mid-Qing dynasty as a theoretical basis for social reform.
