Duke Yansheng
From 1127 up to the Mongol-led Yuan dynasty, there were two Duke Yanshengs – one in Quzhou, Zhejiang (in the south) and the other in Qufu, Shandong (in the north). In 1233, Ögedei Khan (r. 1229–1241) granted the Duke Yansheng title to Kong Yuancuo (), a 51st-generation descendant of Confucius from the northern branch.
