Emperor Renzong of Yuan China was the 4th leader of the Yuan Dynasty to rule as Emperor of China and did so between 1311 and 1320. Renzong stood out among the Mongol rulers of China as an adopter of the culture of China. He had been mentored by Li Meng, a Confucian academic. To the displeasure of Mongol nobility he made many reforms - including the liquidation of the Department of State Affairs (resulting in the execution of 5 of the highest ranking officials). Starting in 1313 examinations were introduced for prospective officials - testing their knowledge on signficant historical works - in 1315 300 appointments went to Mongols, with an extra quarter of the positions being given to non-Chinese people. As well as this he codified much of the law.
