And what does that mean? Sorry I'm new to the game and never experienced anything like that.
All I know is royal marriages, vassals, allies. Anyway, is there a way to break this personal union? I mean, what would you do in my situation? I need Sicily!!
A personal union is formed when 2 nations have a royal marraige and one of those nations loses their kings without an heir. If the other nations prestige is high enough a union will form. This is rare however and is typically formed by claiming the thrown. Which is an option in diplomacy and gives you the chance to force that country into a union. It makes them your ally for life basically, and high relations. They can insult you if they are the junior partner. Every time your ruler dies or something like that there is a slim chance that you will inherit that nation. If you want to get out of one, just continue to insult the leading partner in the union until your relations are negative I think. This will mean that a war will occur and you will try to get out of the union if you win. And if you lose, the union will continue.
