The term "civil war" among the Russian reader is associated exclusively with the events of 1917-1920. However, there were three more bloody civil wars in Russia: the conflict between the sons of Vladimir Krasnoye Solnyshko at the beginning of the 11th century, the war of the descendants of Dmitry Donskoy in the middle of the 15th century and the Great Troubles at the beginning of the 17th century. Each of them lasted several years, led to huge casualties and destruction, often accompanied by foreign intervention. This book is devoted to the study of these civil wars.
