This was my 3rd EU3 game as the Papal States. My main objective here was to spread Christendom and crush the reformation, not to conquer a large territory. So whenever I conquered a sizeable amount of land I would release a vassal, in the end I had created a Confederation of God.
There was not a single non Catholic Christian nation left when the game ended, though there are some remnant provinces. I got really scared when 7 years before the game ended the UK decided for some reason to become protestant.
The full extent of my Confederation. My vassals are: Achea, Tripoli, Bosnia, Armenia, the Knighs, Romania,Paraguay,Quebec, Netherlands, Canada and the USA.
