I'm currently working on a TL with a strong focus on an alternate 30 Years' War (probably won't be 30 years long, but has similar qualities to OTL's conflict). Since the POD takes place over a decade before the outbreak of war in OTL, I'm thinking about giving this TL's *Thirty Year's War a different sparking point other than the Defenestration of Prague. What sort of events would you see as inciting a similar sort of long-reaching destructive religious war similar in scope to the 30 Years' War in OTL occurring in the latter half of the 1610s?
