The article is devoted to definition of specifics of implementation of one-man rule among Rurik’s princely dynasty during X-XII centuries. The author analyses the process of establishing of sole authority of Kiev princes Ruriks in Rus’ and determines the main activities of the dynasty representatives in consolidation of East-Slavic tribal unions.The feudal structure that existed in Rus’ (and later in Russia) about thousand years has begun forming in the 9th -century. Early feudalism lasted during the 9th–11th-century. It coincided with a period of political-territorial forming of Rus’ state. It was a kind of transition, when the central government was unable to restrict the local nobility rights. The Varangian princes have defeated Khazars with the goal territory consolidation Slavic tribal unions, and relying on military retinues, slowly, one by one, have subordinated the south-eastern tribes and put on them tribute during the 9th– 10th-century. They had implemented a number of authority-management reforms that allowed to the Kievan princes to take into their hands from local princes the right to individual-private solving of political, power and financial prob-lems in Rus’ space. The Riurik's dynasty began the process of unification of East Slavic tribal unions in one state during the 9th –10th-century. At the period of sustainable dynasty development (during 11th century – 30-ies 12th century) all East Slavic tribal groups found themselves in the ―Empire Riurik's dynasty‖. It has become an important political and military force in Eastern Europe: successful campaigns has carried out against Byzantine Empire, favourable trade agreements were concluded with emperors, Kievan princes established dynastic ties with many of the most powerful royal families of Europe
