nor even of princely stock, but I am of princely birth." Igor' was then brought forward, and Oleg announced that he was the son of Rurik. They killed Askold and Dir, and after carrying them to the hill, they buried them there, on the hill now known as Uhorska (Hungarian hill), where the castle of Ol'ma now stands.' Then 'Oleg set himself up as prince in Kiev' () 'and declared that it should be the mother of Rus' cities.' According to the text's aforementioned chronology of Oleg's accession 29 years after Michael III in 860, Oleg's reign should have begun in 889 rather than 881/2. 883: Prince Oleg conquers the Derevlians. 884–885: Prince Oleg defeats the Radimichians and the Severians, bringing them under his rule. 907: Prince Oleg launched an incursion against the Greeks, resulting in a favorable treaty for Rus'.
