This article examines the formation and dissemination of Arabic and Uighur scripts in the written culture of Turkic peoples, analyzing their significance in political and economic processes from a historical perspective. The Uighur script, developed on the basis of the Sogdian script, served as a key medium for political and commercial documentation in Eastern Turkestan and adjacent regions. With the advent of Islam, the Arabic script became predominant in state administration, taxation, property records, and religious as well as scholarly works across Transoxiana and other Turkic territories.
