Navarre could have been managed, I guess... (I'm thinking about Henry IV of France here...)
Protestant Venice?![]()
Well, in Italy there were the Waldensians, who later became a Protestant Church even though they predated it. Maybe they make more converts.
I'm not really sure why Spain and Italy didn't have much of the Reformation IOTL though, that would help to clear it up.
You are confusing Navarre in Spain with what was called Kingdom of Navarre in France. Spanish Navarre was not different from the rest of Spain.
By the way the Reformation did not take hold on Spain because they had their "reformation" of their own. During the years of Isabel and Ferdinand the Cardinal Cisneros started a reform of the uses of the clergy, an improvement on their education and a cleaning of some vices. It was so harsh that there were even priests that fled to Morocco and there they converted to Islam.
