"Sach of Russian history" is a correct and clear description of domestic history from ancient times to 1917. The book was first published in 1927 in Prague in Russian. In it, Russia is proclaimed the "Eurasian" country, as it was located in four latitudinal zones: the tundra, the forest zone, the steppe and deserts, which are the geographical basis of Russian history.
