The Imperial Seal of the Mongols is a seal (tamgha) that was used by the Mongols. The imperial seals, bearing inscriptions in Mongolian script or other scripts, were used in the Mongol Empire, the Yuan dynasty, and the Northern Yuan dynasty, among others.
According to Plano Carpini, the Russian handicraftsman, Kozma, made a seal for Güyük Khan. This seal might have been a seal used to stamp the letter to Pope Innocent IV.
The Dulo clan was a ruling dynasty of the Bulgars, who were of Turkic origin. It is generally considered that their elite was related to the Huns and the Western Turkic Khaganate. Particularly, it is said that the Dulo descended from the rulers of Old Great Bulgaria. This state was a centralized monarchy from its inception, unlike previous Hunno-Turkic political entities, which were tribal confederations.
The royal family and rulers of Old Great Bulgaria (632–668) and the first half of the First Bulgarian Empire (681–1018), in their prince lists (Nominalia of the Bulgarian khans) claimed through descent from Attila through Irnik, possibly Attila's attested son Ernak. During the pagan period, the succession of clan leadership was based on traditions brought over to the Balkans from the Eurasian Steppe, which include the rulers' divine ancestry. At the head of the clan was the Khan, who reigned as the head of state, military leader, and probably high priest of the Bulgar god, Tangra.
