Book excerpt: The Mongolian Yuan dynasty, 1272-1368, is a short but interesting chapter in the long history of Sino-Mongolian relations. Faced with the challenge of governing a huge sedentary empire, the traditionally nomadic Mongols acceded to some Chinese institutional precedents, but, in large part, adhered to their own Inner Asian practices of staffing and administering the government apparatus.Yuan administrative documents provide information that permits a fairly accurate reconstruction of the day-to-day functioning of the local government bureaucracy. From these materials, Elizabeth Endicott-West has put together a detailed picture of the Mongols' methods of selecting local officials, the ethnic backgrounds of officials, and policy formation and implementation at the local level.
