Universal Monarchy
This mod uses an event chain to simulate the rise of Charles V of Spain, Holy Roman Emperor. This mod overwrites the vanilla "Strategic Marriage" events.
After 1500, if Castile/Spain and Austria are both rivals of France or rivalled by France, Charles can be born in the former. When he inherits the throne, he will also bring in the Low Countries to Spain.
Once he is King of Spain, an event will fire making you Holy Roman Emperor and giving you a PU over Austria. When Charles dies or abdicates via event, the player will get an event which forces the partition of the empire, or can be declined in return for severe penalties.
This mod is not intended to be balanced – the Habsburg Empire dominated Europe for nearly fifty years. However, for a player France, Ottomans, Netherlands, or Portugal, it offers a very scary enemy for roughly forty years in Europe.
In addition, this mod adds a special event for the "Sack of Rome" within the army professionalism events.
Future plans (possible):
Event chain for the Emperor to back the Sforzan conquest of Milan, with inheritance likely if he does not have a heir
Offset the League War so it occurs in the 1600s, add Schmalkaldic League events (so effectively have two League Wars)
Make conquering provinces within the Empire far more difficult, forcing countries to rely on personal unions, conquering non-HRE territory, or waiting for periods of chaos in the Empire
Make adding provinces or countries to the Empire far more difficult without later reforms (historically basically never happened)
Find a way to make Catholic and Protestant accepted faiths within the HRE, but not Reformed
More events for the Dutch Revolt and a more logical and historical trigger
Tweak Spanish and Austrian missions to be more historical and logical (i.e. Spain never directly conquered Tuscany)
