Chancellery and Diplomatic Practices in Central Asia during the Mongol Period as Shown in Old Uyghur and Middle Mongolian Documents.

Due to its central location the Chaghadaid ulus played a key role in the interregional diplomatic connections in the Mongol period. Unfortunately, comparing to the other three ulus es of the Mongol Empire we have a very limited number of written sources concerning the Chaghadaid realm. The aim of the present paper is to show how the new results of the philological study of the Old Uyghur and Middle Mongolian documents can throw new light upon our knowledge about the diplomatic practices in the Chaghadaid ulus. The paper concentrates on the two most important institutions which facilitated diplomatic relations: the chancelleries and the postal system. [ABSTRACT FROM AUTHOR]
