This is a designation designed to clearly signal that they were the people who eventually gave rise to the state of the Kyivan Rus, using the ethnic names known to both Slavs and Byzantines for the Norse in, what is now, Russia and Ukraine. The Russian Primary Chronicle also claims that, while Rurik was establishing himself at Novgorod, two other Rus leaders – Askold and Dir – travelled southward down the river Dnieper and established their rule in the settlement later known in Russian as Kiev (Ukrainian: Kyiv). After the destruction of the Kyivan Rus state, by the Mongols in the 1240s, Russian rulers (based in Moscow) have frequently referenced these Norse origins when trying to enhance their power and secure control over the Ukrainian lands.
