Prince Igor Svyatoslavich Novgorod-Seversky (1151-1201) went down in history thanks to a single event - an unsuccessful campaign against the Polovtsians in 1185, as a result of which for the first time five Russian princes were captured in a foreign land. This campaign is described in two chronicles, and most importantly, in the epic poem “The Tale of Igor’s Campaign.” It was she who brought Igor fame - hardly well-deserved, for he was only one of many appanage rulers of that time, not the most noticeable and not the most outstanding. On the pages of the book by Doctor of Historical Sciences Sergei Alekseev, it is not poetic heroes, but historical characters - Igor and Svyatoslav, “Buy Tour” Vsevolod and his namesake Big Nest, Konchak and Yaroslavna. This is not a classic biography, but a portrait of a supporting character, emerging against the backdrop of a turbulent, eventful era of internecine wars and campaigns in the Steppe, noble deeds and perjuries. The most notable of his actions, which gave Russian culture and history “The Tale of Igor’s Campaign,” became the most unfortunate for the prince, but immortalized his name.
