Shang Yue (Chinese: 尚钺; pinyin: Shàng Yuè; Wade–Giles: Shang Yüeh; 1902 – January 6, 1982) was a Chinese Marxist economic historian, author and professor at the School of History at Renmin University of China. Before becoming a historian, he also wrote fiction. He taught literature to Kim Il Sung for a short time at Yuwen Middle School in Manchuria. In China, he is primarily known for his work on the idea of the sprouts of capitalism: that proto-capitalism and class struggle had existed in the earlier Chinese history. His purge in 1958 foreshadowed the Chinese Cultural Revolution as his ideas on Chinese economic history conflicted with those of Mao Zedong. After his purge he continued to work on history, but stayed out of public until Mao's death in 1976. His work also gave a lasting effect in Korean nationalist historiography. Source: Wikipedia (en)
