A tamga or tamgha "stamp, seal" (Mongolian: tamag, Turkish: damga) is an abstract seal or stamp used by Eastern Eurasian nomadic peoples and by cultures influenced by them. The tamga was normally the emblem of a particular tribe, clan or family. They were common among the Mongols, Scythians, Sarmatians, Bulgars, Alans and all Turkic peoples, including Khazars and Uyghurs. Neighboring sedentary people sometimes adopted tamga-like symbols; for example, the stylized trident tamga, or seal were used by various peoples of Eastern Europe and Asia: Kushan Empire, Bulgarians, the Dulo clan, the Rus', Khazars, Kipchaks, Tatars, Tatars, Lithuanians and Poles. Archaeologists prize tamgas as a first-rate source for the study of present and extinct cultures.
