Can we please stop reading history and stories as things that people in the past slavishly believed to the letter like unthinking machines? Of course stories about leaders glorify them. That’s just the victors writing history. Of course leaders and their sycophants mostly bragged and embellished.
Did people have a reason to believe those things in their heart, though? What does “divine right” matter to a serf?[1]
Of course we all know that we just don’t automatically believe everything about some person just because his bank account is large enough, or he is a high authority in the military, or the so-called democratic process chose him to be a representative of something. But somehow we tend to speak of the Middle Ages like, oh that’s when everyone believed in Divine Right (or whatever) and no one was the slightest bit sarcastic about it. (But then what were all those armies and fortresses about? If everyone toed the line...)
It’s like cynicism was only invented in 1970 or something.
And the answer to the question has got nothing to do with leaders per se. It’s just that political liberalism reigns supreme, which is incredibly individualistic. (The dominant political philosophy is very relevant to the conception of leadership.)
