Is the ferment of the peoples of the west at the end of the eighteenth century and their drive eastward explained by the activity of Louis XIV , XV , and XVI , their mistresses and ministers, and by the lives of Napoleon, Rousseau, Diderot, Beaumarchais, and others?

Is the movement of the Russian people eastward to Kazán and Siberia expressed by details of the morbid character of Iván the Terrible and by his correspondence with Kúrbski?
