> The Catalans never voluntarily agreed to be part of Spain as far as I know. They were essentially annexed a long time ago.
When did that happen?
When did that happen?
Since then. I think that the source of conflict is that, for multiple reasons, catalans wanted to be part of a bigger political reality, but in "their" terms. And Spain, as a centralized system, didn't like that, doesn't like that and will not like that. To Spain, Catalonia is a property, why would they let it go? After all, it's their right (of conquest) to keep it.
Anyway, they level of independence that Catalonia has had in the last decades is much higher that before that “annexion”.
I am sorry to say, but this is the misleading part. You can't compare the situation hundreds of years ago with today's standards. Politically, Catalonia has less level of independence than 300 years ago. After all it had its own political institutions, courts, laws and coinage of money; all of them separated from the Kingdom of Castile.
The annex I was referring to was political, economical, legal and monetary unification after Catalonia defended a different candidate for the crown. And this is the level of autonomy that some Catalans wanted to regain.
That’s a very good point. But for some reason some people can’t leave 1714 behind!
