About the book: 2012 / The book by the original author G. N. Kudiy is dedicated to the interesting, full of dynamics and drama, history and culture of the Grand Duchy of Lithuania, Russia and Zhemoytsk (GDL) - the largest state in Europe during the late Middle Ages. In a bright and intelligible form, it allows us to restore, primarily for the Russian reader, the historical truth about the place and role of Russian Atlantis - the Grand Duchy of Lithuania in the development of Eastern Europe and the formation of Russian statehood, which was deliberately distorted and thoroughly forgotten in the previous two centuries. And also shows, using the example of this state, the mortal danger and even death for any ethnic group of thoughtless loss of their national identity, traditions and faith.
