Hugo Grotius gets called the father of international law, which sounds like a fancy title for a guy from the 1600s, but when you actually think about what that means, he was one of the first people trying to write down rules for how nations ought to treat each other fairly, even in wartime, even between countries that didn't like each other one bit. I spent a good chunk of my working life as a union grievance rep, which is a much smaller stage, obviously, arguing about seniority and safety violations instead of nations, but it's the same basic instinct — somebody's got to write the rules down so the guy with less power isn't just at the mercy of whoever's bigger. Nobody thanks you for that kind of work while you're doing it. You just get called difficult. Grotius was doing that four hundred years before unions existed, trying to get powerful people to agree there were limits even they had to respect. Took guts to write that down when plenty of kings would've rather he hadn't.
