Oleg of Novgorod
Anonymus writes of a war between the Hungarians and the Kievan Rus', ending with the victory of the Hungarians, who were commanded by Álmos. The Russian "Primary Chronicle" refers to a "Hungarian hill" at Kiev in connection with the town's occupation by Oleg of Novgorod in 882. The same chronicle mentions "a castle of Ol'ma" "(Олъминъ дворъ)" standing on the same hill. George Vernadsky says that this fortress had been named after Álmos, but this theory has not been widely accepted by historians.
