The Old Turkish inscriptions that were written roughly between the beginning of the eighth and the middle of the ninth century A.D. and represent the first testimonies of a Turkish language, include important information about contacts of the ruling Türks and later the Uighurs, who were also Turkish-speaking, with other peoples inside and outside of their el, i.e., their steppe empire. This information is partly explicit, when, for example, we read about a delegation being sent to the other side, and partly implicit, by which we mean outside influences that we can trace in the texts in different ways.
