The earliest mention of Rurik is contained in the
Primary Chronicle, traditionally ascribed to
Nestor and compiled in , which states that
East Slavic and
Finnic tribes in 860–862 (including the
Chuds,
Slovenes,
Krivichs,
Meryans and
Ves) "drove the Varangians back beyond the sea, refused to pay them tribute, and set out to govern themselves". Afterwards the tribes started fighting each other and decided to invite the Varangians, led by Rurik, to reestablish order. Rurik came along with his younger brothers
Sineus and Truvor and a large retinue. According to the chronicle, Rurik was one of the
Rus', a
Varangian tribe. Most historians believe that the Rus' were of Scandinavian origin, more specifically from what is currently coastal
eastern Sweden around the eighth century. According to the prevalent theory, the name
Rus is derived from an
Old Norse term for "the men who row", from an older name for the Swedish coastal area of
Roslagen. Sineus established himself at
Beloozero, and Truvor at the town of
Izborsk. Truvor and Sineus died shortly after the establishment of their territories, and Rurik consolidated these lands into his own territory, extending his rule in northern Russia. Rurik is said to have remained in power until his death some time in the 870s. On his deathbed, Rurik bequeathed his realm to
Oleg, who belonged to his kin, and entrusted to Oleg's hands his son
Igor, for he was very young. Oleg moved the capital to
Kiev (by murdering the then-rulers and taking the city) and founded the state of
Kievan Rus', which was ruled by Rurik's successors (his son Igor and Igor's descendants). The state persisted until the
Mongol invasion in 1240. ==Legacy==
