So, suppose that for one reason or another Martin Luther is killed, either before he can be spirited to safety or because Frederick III doesn't do so. What sort of changes are we looking at for the Reformation?
Does the Reformation radicalize, mostly fail in the first generation, and come out with a bunch of quasi Anabaptists? Does someone else emerge to moderate, as Luther did? Or does Luther go down in history as an abortive first attempt that will re-emerge in a generation?
