This book is fundamentally different from all previously published books about Yesenin, because its creation was not hindered by any ideological dogmas. During the work, the authors managed to familiarize themselves with a huge number of archival documents that had previously been inaccessible. The book traces plot lines that have not yet been developed in literature: Yesenin and Trotsky, Yesenin and Stalin, Yesenin and the Romanov family. The poet’s relationships with Zinaida Reich, Isadora Duncan, and other companions of his life are illuminated in a new light, as is Yesenin’s role in the emergence of Russian nationalism in the 1920s. Using many previously unknown documents, the book includes chapters about Yesenin’s stay abroad and, of course, about his tragic death.
