The Hungarian and Turkic people (or rather, peoples) are connected in many cultural and even genetic ways. The Byzantine emperor Constantine VII Porphyrogenitus called the Hungarian conquerors ‘Turks’, and the sons of the House of Árpád (Turul gens in medieval Hungarian sources) were later called ‘Princes of Turkey’ by the Byzantines. In the origin myth of the Hungarian royal dynasty, the ‘Turul bird’ is also of Turkish origin, as the symbol of the Sky and of the supreme God of Turkish myths, where it appears as toġrïl or toğrul.
