The policy of the Turkish State was aimed at taking control over the
great trade road. By 580's CE, the Turkish state expanded to annex
numerous aimags with people of diverse nationalities. They defeated
the Ephtalit State in the west and subdued the Kirghiz people living
in the Enisei basin of Siberia in the North. During the period of the
Turkish State its territory expanded to reach the Korean peninsula.
By the end of 4th century CE, the Turkish State was divided into the
eastern and western parts. And Uighur people, who were a part of the
Turkish State, defeated the eastern Turkish State in 745 CE. Thus the
Uighur State became the successor of the Turkish State.
