Eurasian nomads
A tamga or tamgha "stamp, seal" (, Turkic: tamga) is an abstract seal or stamp used by 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 Eurasian nomads throughout Classical Antiquity and the Middle Ages (including Alans, Mongols, Sarmatians, Scythians and Turkic peoples). Similar "tamga-like" symbols were sometimes also adopted by sedentary peoples adjacent to the Pontic-Caspian steppe both in Eastern Europe and Central Asia, such as the East Slavs, whose ancient royal symbols are sometimes referred to as "tamgas" and have similar appearance.
