Oleg of Novgorod (олег)

Oleg of Novgorod (Old East Slavic: Ѡлегъ; Old Norse: Helgi; Russian: Олег Вещий, romanized: Oleg Veshchy, lit. ’Oleg the Prophet’; Ukrainian: Олег Віщий) was a Varangian prince (or konung) who ruled all or part of the Rus’ people during the late 9th and early 10th centuries. He is credited by Rus’ Chronicles with moving from either Staraya Ladoga (Old Norse: Aldeigjuborg) or Novgorod, and seizing power in Kiev (Kyiv) from Askold and Dir, and, by doing so, laying the foundation of the powerful state of Kievan Rus’. He also launched an attack on Constantinople, capital of the Byzantine Empire. According to East Slavic chronicles, Oleg was the supreme ruler of the Rus’ from 879 to 912.
