Abstract
This paper presents the philological analysis of one of the Ardabīl documents: An Uigur- Turkic decree of the Timurid prince Mīrān Šāh, dated to 800 AH/1398 CE. It is the oldest of the Timurid Uigur-Turkic decrees thus far known, and the only one accompanied by a Persian summary. It attests to the patronage of the Timurid rulers for the Safavid Order in Ardabīl, and offers significant information on the administration, chancellery, taxation, and many other aspects of the early Timurid rule, and merits further investigation from the historical viewpoint.
