For historical reasons, the vast majority of documents on the history of Ukraine in the 16th and 19th centuries are currently stored in Russian archives, to which Ukrainian researchers do not have access. Therefore, today there is an urgent need to bring these documentary treasures to our specialists and all those interested in the Ukrainian past, because their study will allow us to better understand this dramatic period in the history of the Ukrainian state and learn its lessons.

The book includes documents relating to the history of the Ukrainian Hetmanate of 1690-1709, In particular, the corpus of the so-called Baturyn archive, taken by O. D. Menshikov from the Hetman's residence during its destruction in 1708. The documents represent the entrance office of Hetman Ivan Mazepa, the only Hetman's archive of the late seventeenth and early eighteenth centuries that has survived to this day. In addition, originals and copies of Mazepa's universalis, which are not known to the general public, are presented. The publication will be useful for Ukrainian history lovers and researchers, students and teachers.
