O rone could have teh crazy idea of letting referenda decide about the issue. Crazy, I know. And if referenda arent allowed, a war seems justifid to me.
Yes a referenda could be the soultion, but the Holsteins wanted the entire Schleswig too, and was against a referenda. So it wasn't just poor innocent Germans persecuted by evil Danes. Beside the referenda could have been arranged after the Prussian conquest, so it wasn't like it Denmarks fault alone.
Anyways, "it were" - mind to explain a bit more, please?
You know how the HRE was a mess beyond explanation especially in a foreign language, this is one of those kind of thing, it goes back to the medieval periode and wasn't really a problem, before modern nationalism began. But it's a little like this, Schleswig was part of Denmark but the Holsteins nobles has special rights in Schleswig, including one law for entire area, and the Danish king promissed to never remove those right, Denmark then later tried to remove those right, and Holstein rebelled.
It's one the reason that a multiethnic federation was only peaceful solution and it would likely have been supported by a majority among both people, and if it wasn't for braindead Nationalliberals in Copenhagen it could have worked.
