 The Russians and "Yem" had frequent conflicts from the 11th or 12th century onwards.The eastern Finnic Votes, "Korela" (interpreted as Karelians in general or more specifically as the Karelians on the southwest coast of the Ladoga) and Izhorians are all mentioned as allies of Novgorod, said to have been fighting against the Yem even without Novgorod's direct involvement, possibly over control of land area in central and eastern Finland; this territorial feud manifested in annual retaliatory expeditions that featured merciless treatment of the settlers of the opposing tribe.The earliest possible mention of hostilities is from the Laurentian Codex which records in passing that the Novgorodian Prince Vladimir Yaroslavich was at war with the "Yam" in 1042 AD.
