Abstract
Diplomacy was in its formative stages during the Middle Ages, and states used advanced diplomatic tools in their interactions. Diplomatic methods such as treaties, mediation, marriage alliances, and cooperation offered distinct advantages and reflected the role and position of a country in the international arena. Analyzing the interstate relations of the Qarakhanids and Saljuqs, we found that they initially had similar state structures, cultural and economic traditions, and religion, but evolved in different directions as a result of their interactions. This article argues that the diplomatic methods and tools used by a state reflect its level of internal development and affect the effectiveness of its actions. Moreover, the article offers a new holistic perspective on interstate relations in the Turkic world.
