Didn’t the religious wars of the Renaissance and early Baroque happen over a number of decades?

Yes, over many decades. But the selective memory of the Calvinists would have you believe it all just happened on St. Bartholomew's Day.

selective memory ... would have you believe it all just happened on St. Bartholomew's Day.

I don't think it's limited to one brand of protestantism. There were fights going on in Scotland as late as the mid-18th century now that I think about it. We won't get into Ireland.
