I guess because history is full of this kinda stuff, sadly. In Croatian school system (unless you study history, I assume?) half the curriculum is world history and European history (with like... only a few hours of international History jammed together) and the other half is our country or local regional history that affect Croatia in some way.

I can't fathom where'd they'd slot all the horrendous historical anecdotes amongst all the horrendous historical anecdotes Croatia has been a part of. There would need to be a lot more history.

Also, there was a period of "recent history" (but maybe that was in highschool) that was more political/nuanced from what I very vaguely remember
