Abstract:

When we research the main sources of the Middle Ages, especially the period of the Seljuk State, we see how important the Azerbaijan region was for the people of Turkmen origin. With the increase in the population of Oghuzs (Turkmen) from the beginning of the 11th century, not only the geography of Iran but also the Anatolian lands became one of these regions to be settled. That's why we can see crowded migration waves to these regions over time. In fact, how important it was to make the Azerbaijan region a military upper zone in order to be able to settle in Anatolian lands and to fight against the Byzantines in the thought of that period would show its effects in the later processes. When we consider the geographical and political characteristics of the Azerbaijan region, we can see how important this region was for the rulers of the Seljuk State. In this research, we will examine the main sources of the period and examine how the Seljuk rulers evaluated the Azerbaijan region both in order to settle the Turkmen in their immigration policy and to pass to the Anatolian lands.
