Leonhard sets out not simply to write a history of events, but to help his reader understand the greater meaning of the war for the participants (who included virtually everyone in the world to one extent or another) and to us in the twenty-first century. And to arrive at that understanding he identifies a collection of leitmotifs that provided the living reality for the people of the time: realities of social condition, class, economics, demographics, relationship to local culture as well as to state and nation for example, but also of aspirations, possibilities, experiences, expectations, and people’s (ruling elite, bourgeoisie, working class) general knowledge of both the world and the local neighborhood.
