Prince Oleg, nicknamed “The Prophetic,” ruled in Novgorod at the end of the 9th century as Rurik’s successor and “uncle” (educator) of his son Igor. He captured Kyiv, uniting the two main centers of Ancient Rus', made a daring campaign against Constantinople with his Varangian squad, and fought in the Caucasus and the shores of the Caspian Sea. Apart from this, almost nothing is known about Oleg’s life and mysterious death. Legends about his deeds were reflected in the first Russian chronicle, the Tale of Bygone Years, and later embodied in the “History” of N. M. Karamzin and the famous “Song of the Prophetic Oleg” by A. S. Pushkin. The book by the famous historian Evgeny Pchelov is the first attempt to reconstruct the biography of Oleg-Helga based on a wide range of Old Russian, Scandinavian, Byzantine and Eastern sources of the era when, through the efforts of the “prophetic” prince, a multinational Old Russian state was created in eastern Europe.
