Andronicus-Christ (aka Andrei Bogolyubsky), Dmitry Donskoy, Sergius of Radonezh (aka Bertold Schwartz), Ivan the Terrible, Elena Voloshanka, Dmitry “The Pretender”, Marina Mnishek and Suleiman the Magnificent on the pages of the famous Epic Shahnameh All the results presented in the book , received recently, are new and published for the first time. The famous “ancient” Persian Epic Shahnameh is a grandiose and very popular source, which is believed to tell about events in the territory of Persia, Greece, Byzantium in “the deepest antiquity”. The Shahnameh brings to us information about hundreds of characters and many important events. In this book we show that this huge Epic actually speaks about the events of the 12th–18th centuries, which unfolded mainly in the Great Empire of the 13th–17th centuries. Most of the Shahnameh tells, as it turned out, about the Great Troubles in Rus' in the 16th - early 17th centuries, that is, in the metropolis of the Great Russian Empire. As the authors note, the reconstruction they propose is still conjectural. At the same time, the authors are responsible for the accuracy and reliability of the dating they calculated.
