The Swedish king Charles XII (1682-1718) is so firmly entrenched in Russian history and Russian consciousness that when it comes to the Northern War or the actions of Tsar Peter I, we automatically remember his historical opponent. Despite his wide popularity Despite the extraordinary, grandiose personality of Karp and the abundance of legends and myths, not a single detailed monograph about him has yet appeared in Russia. The author of the book, who devoted most of his life to studying the political development of the Scandinavian countries, tried to fill this gap. As a result, the reader got the opportunity to look at famous events from the other, Swedish side.
