The Westphalian peace reflected a practical accommodation to reality, not a unique moral insight. It relied on a system of independent states refraining from interference in each other's domestic affairs and checking each other's ambitions through a general equilibrium of power. No single claim to truth or universal rule had prevailed in Europe's contests. Instead, each state was assigned the attribute of sovereign power over its territory. Each would acknowledge the domestic structures and religious vocations of its fellow states and refrain from challenging their existence.[8]

What's wild is that England too underwent a kooky civil war around the same time as Germany but for totally unrelated reasons. They just happened to have an out of control king who had to be put down like a shitpit, and somehow this triggered about a decade of fighting between religious sects all over the British isles
