 The Qing Dynasty, which ruled Mongolia from 1694 to 1911, entrusted rule in Mongolia to the descendants of Genghis Khan, who were also called "Noyon".The term "Noyon" in this epoch acquired the connotation of nobleman, since Mongolia was mostly at peace.After 1921 the word "Darga" (boss) replaced the aristocratic "Noyon" as the term for officials.
