In one well written book you get political history of 1200s, the fall and revenge of imperial House of genius, the rise and fall of a world ruler who not, story of Papacy vs Empire, birth of nationalism, conspiracies, etc
But you'd rather read turgid stuff about "alterities"?
If people have little time or limited inclination to read, don’t waste it on theory: just give them a Runciman book. History is a much better teacher than theory. Strongly recommend The Sicilian Vespers. Runciman is a wonderful writer & true history is more amazing than fiction.
