The crusades weren’t that bad, nor large in scale… Now let me introduce you to the 30 years war, this made WW1 and WW2 seem like a stroll in the park, it killed as many Germans as the Black plague, yes 1/3 of all Germans were killed over the course of said war.

Best part? the war was about should you be Catholic or Lutheran, the conclusion: “we don’t care anymore be whatever your local lord is”
