State of Russia in the 9th - early 10th centuries
On the territory occupied by Slavic tribes, two Russian state centers were formed: Kiev and Novgorod, each of which controlled a certain part of the trade route "from the Varangians to the Greeks." In 862, according to The Tale of Bygone Years, the Novgorodians, wishing to end the internecine struggle that had begun, invited the Varangian princes to rule Novgorod. The Varangian prince Rurik, who arrived at the request of the Novgorodians, became the founder of the Russian princely dynasty. The date of the formation of the ancient Russian state is conventionally considered 882, when Prince Oleg, who seized power in Novgorod after Rurik's death, undertook a campaign against Kiev After killing Askold and Dir who were ruling there, he united the northern and southern lands into a single state. The legend about the vocation of the Varangian princes served as the basis for the creation of the so-called Norman theory of the emergence of the ancient Russian state. According to this theory, the Russians turned to the Normans (as the natives of Scandinavia were then called) in order for them to put things in order on Russian soil. In response, three princes came to Russia: Rurik, Sineus and Truvor. After the death of the brothers, Rurik united the entire Novgorod land under his rule.
