The earliest archaeological signs of human beings in the area of Mordovia are from the Neolithic era. Finno-Ugric Mordvins are mentioned in written sources from the 6th century. Later, Mordvins were under the influence of both Volga Bulgaria and the Kievan Rus. Mordvin princes sometimes raided Muroma and Volga Bulgaria and often despoiled each other's holdings.
