 Modern historian Ma Feibai considers the significance of Duke Xian's abolition of human sacrifice in Chinese history comparable to that of Abraham Lincoln's abolition of slavery in American history.After the abolition by Duke Xian, funeral human sacrifice became relatively rare throughout the central parts of China.However, the Hongwu Emperor of the Ming Dynasty revived it in 1395, following the Mongolian Yuan precedent, when his second son died and two of the prince's concubines were sacrificed.
