Cursed Castile into Andalusia Guide Eu4

If you want to stop your allies from grabbing land you want, set it at a province of interest

Why the heck did you release Asturias instead of destating?

you dont need to give the lands to a vassal, you can just destate the provinces instead

What if you give lands to a vassal after you get the aragonese pu event,and use the subject interaction or events to take provinces necessary to form andalusia ? I suppose it would take abit longer to do but you would indirectly owj aragonese lands aswell.
Great video,I may try this someday lol
