C’mon, so lame. I mean, I agree with the comments saying that being obsessed with a war is dumb, but obviously the right answer would be the Thirty Years War. Far more factions, more casus belli, more fights. Plus, it bolstered German nationalism, which led pretty directly to the Great War, which led to World War II, so those are technically part of its history.

But maybe I’m biased, because my surname originated in the Huguenot diaspora?
