We had a bloody reformation here! Three times over, in fact, first Henry VIII, dozens burnt, both diehard Roman Catholics and over- enthusiastic (from Henry's point of view) Reformists. Then Mary tries to turn it back, they didn't call her Bloody Mary because of the tomato juice. Then Liz trumps her. Her burnings were relatively few, hanging, drawing and quartering (castration and gutting alive) rather commoner- though it has been pointed out that there were fewer executions for treason and heresy in her 40-odd years than in Henry's last 10 years.

Add in the Pilgrimage of Grace, the revolt of the Northern Earls, and various minor disturbances, and it all amounts to as rough a ride as most places had.

And of course some historians suggest that the slightly- less- than- peaceful English civil war was the final fighting out of the left-over issues from the Reformation. But even then, it wasn't fully resolved until 1688.

The opportunity to create a tolerant state was available in 1600- the Dutch had already done it. The real problem was that the monarch wasn't made (fairly) irrelevant politically until the act of Settlement.
