Peace of Augsburg: Princes Choose Their Religion, Catholic or Protestant

For 38 years, Lutherans and Catholics had been killing each other across German lands. The Peace of Augsburg ended the fighting by doing something radical for 1555: accepting that two versions of Christianity could legally coexist in the same empire. The formula — cuius regio, eius religio, 'whose realm, his religion' — let princes choose their territory's faith. It didn't extend that choice to individuals. And it excluded Calvinists entirely. The peace held for 63 years before Europe went back to war. Then it was far worse.
