Religious rebels are fun.
Castille collapsed to Protestant Zealots and now control a kingdom of all Catholics, except for that province above Madrid.
Catholic Zealots then rebelled away to the Papal State, Catholic Granada gained its independence and Reformed Madrid rebelled to the Palatinate, which Bradenburg inherited.
Also Aragon rebelled from France and somehow survived. Apparently France doesn't have a navy.
Then there's Britain:
It seems they had their entire army in America so all of their Reformed provinces revolted to Cologne, their Catholic provinces revolted to the Papal State (and then declared independence as England), and Navarra.
Tyrone revolted and took all of Ireland, then immediately formed Ireland.
Britain has since moved their capital to South America. Can they even be called Britain anymore?
Finally, I leave you with the glorious Republic of Brittany, which doesn't actually own any part of Brittany.
