The author of the book - the famous medievalist Helmut Georg Koenigsberger (Helmut Georg Koenigsberger) - analyzes the events that took place in the countries of both Western and Eastern Europe, closely linking them with those processes in social and cultural life that developed in Byzantium, the Islamic world and Central Asia. Europe in 400-1500 at G. Königsberger is by no means a "dark age," but a very dynamic period, at the end of which a value system was formed that had a huge impact on all countries of the world.
