The invasion of the Mongols in the territory of Central Asia, in turn, contributed to the emergence of new tribes and nations. In particular, in the middle of the thirteenth century there was a migration of ethnic groups of jaloyir, barlos, kavchin and arlot to Central Asia. In the first half of the XIII-XIV centuries some groups of olchin, duglat, mongol, sulduz, oyrot, bakhrin, market, mang’it, kungrad and other tribes moved to Movarounnakhr. Even the Turkic Mongols living in Movarounnakhr gradually forgot the term "Mongol" and called themselves "chigatay." B.Manz, M. Haydar and other authors commented on the role of tribes in socio-political life, career and rank, as well as the great power of Amir Temur in distribution. It is possible to conclude that the tribes’ nobles of Amir Temur were widely involved in the posts.
