Specific fragmentation of Russia

The book of a famous historian, academician Nikolai Fedorovich Kotlyar tells about the dramatic period in the history of Russia, when the Old Russian state, collected and held together with the efforts of Vladimir St. and Yaroslav the Wise, began to gradually fall apart into many large and small independent principalities. Rurikovichs agreed in the fratricidal struggle for princely tables, and Russia was involved in the endless whirlpool of internecine wars, military campaigns and robberies. The author, skillfully combining the description of the actions of the main politicians of that era with an analysis of socio-political and economic processes, creates a vivid and at the same time accurate picture of the specific fragmentation of Russia
