Compare the reasons for political fragmentation in Western Europe and in Russia.

In ancient Russia, the main reason for the fragmentation of the state was the struggle for power between the heirs, as well as rivalry.

In Western Europe, large feudal lords fought among themselves for land and power.

In fact, both here and there the struggle took place for the expansion of influence and power. True, for Europe, feudal wars were not as destructive as in Russia. Because in Russia this led to the invasion of the Mongol-Tatars with the subsequent ruin of the Russian lands.
