Feudal fragmentation in Russia
Pan-European tendency of the X-XVI centuries has not bypassedside and domestic principalities. At the same time, the feudal fragmentation of the medieval Russian state had a number of features that distinguished its character from the Western version. The first bell to the disintegration of the integrity of the state was the death of Prince Svyatoslav in 972, after which the first internecine wars for the Kiev throne began between his sons. The last ruler of a single Kievan Rus is the son of Vladimir Monomakh, Prince Mstislav Vladimirovich, who died in 1132. After his death, the state was finally divided into patrimonies by heirs and never again rebelled in its former form.
Of course it was
As for the features of domestic decay,then it lies primarily in the so-called lästvichesky system, in which, after the death of the ruler, the throne passed to his younger brother, and not to his eldest son, as it was in Western Europe (Salic Law). This, however, became the cause of multiple internecine conflicts between the sons and nephews of the Russian dynasty of the XIII-XVI centuries. The Russian lands in the period of feudal fragmentation began to constitute a number of large independent principalities. The rise of local noble families and princely courtyards gave Rus the emergence of the Novgorod Republic, the rise of the Galitsko-Volyn and Vladimir-Suzdal principalities, the creation and elevation of Moscow. It was the Moscow princes that destroyed feudal fragmentation and created the Russian kingdom.
