Rider or horseman is an important symbol in heraldry especially in Eastern Europe. It firstly appeared in the 13th century on the old Russian stamps, coins and seals as a symbolic representation of the ruling knyaz. Since the second half of the 15th century the rider striking a dragon with spear became the coat of arms of Russia especially Moscow along with the double-headed eagle. In the 16th century the shield with the rider were placed on the eagle's chest.
Another type of a rider were Lithunian Pahonia/Vytis which appeared nearly at the same time as the Russian one. But main differences are the absence of a dragon, a sword instead of a spear and the direction of the rider (to the right).
