Özet:
This study examines the foreign policy and diplomacy pursued by the Mongol Khans during the Yuan Dynasty (1268-1369), who held the titles of both Mongol qaghan and Chinese Emperor. Specifically, Qubilai Qaghan, who received the title of Khan at a qurultai held in the city of Shangdu, located in present-day Beijing, rather than the Orkhon region traditionally used for convening qurultais, and without the participation of all Mongol nobles, had to establish his legitimacy throughout his life both among the Mongols and the people he conquered in Asia. For this purpose, he utilized diplomacy and foreign policy as much as conquests. Within the scope of this study, the rhetoric and legitimacy foundations used in diplomacy are examined, taking into account not only the Goryeo kingdom in Korea, which became a vassal of the Mongol Empire but also regional states such as Japan, which did not acknowledge Mongol superiority and dominion, as well as diplomacy conducted with states in Southeast Asia and Europe. During this period, the Yuan Dynasty successfully blended elements of legitimacy belonging to China with those from the Turkic-Mongol tradition in its foreign policy, thereby leaving a lasting diplomatic legacy, especially in East Asia.
