Sviatoslav I of Kiev
The modern "trident" symbol was adopted as the coat of arms of the Ukrainian People's Republic in February 1918. The design has precedents in seals of the Kyivan Rus. The first known archaeological and historical evidence of this symbol can be found on the seals of the Rurik dynasty. However, according to Pritsak, the stylized trident tamga, or seal which was used by Rus rulers such as Sviatoslav I of Kiev and similar tamgas that were found in ruins are Khazar in origin. It was stamped on the gold and silver coins issued by Prince Volodymyr the Great (980–1015), who might have inherited the symbol from his ancestors (such as Svyatoslav I Igorevich) as a dynastic coat of arms, and he passed it on to his sons, Svyatopolk I (1015–19) and Yaroslav the Wise (1019–54).
