It's very popular to create rumors about certain historical figures to which there is no concrete evidence.
Such as the sexual orientation of Abraham Lincoln or the alleged illicit behavior of Lewis Carroll and Hans Christian Andersen.
Understandably, these mostly baseless, though not necessarily false, theories are left out of history books.
However, there are facts about legends of history which have, indeed, been proven true, but are also left out of history books.
Namely, because it's not the sort of information many would consider in polite conversation, let alone be talked about in schools.
Even if it is no less fascinating than anything else we might learn.
