Well, I disagree there.
Hungary wanted to impose Magyar as the language of the state and denied the validity of the ethnic aspirations of its constituent peoples. For a nation that was FOUNDED on ethnic and language rights, this is pretty short sighted.
I am always amused, reading history, how the Hungarians were so totally annoyed at 'German' imperialism in 'their' lands, but were shocked and betrayed that e.g. Croats felt the same about Hungarian imperialism.
If the Hungarians DID formally split from Austria, I'd bet they'd have real difficulties with their ethnic minorities. The Austrians would no doubt incite such unrest, 'what's sauce for the goose is sauce for the gander'. More to the point, the Hapsburgs might want to split off e.g. the Croats and Slovaks and get them back into the Hapsburg empire.
Interesting opinion, but... no.
We are speaking about 1848: Hungary did not wanted to impose hungarian as the state (legistlative and buerocratic) language, because it already happened earlier. And the country certanly not founded on ethnic and language rights, because at that time, nobody cared...
German (Austrian) imperialism in an towards Hungary is quite an interesting topic, but its not on the table in that time, the target was feudalsim and bat-shit-crazy conservatism/absolutism.
So, back to my favourite mania: the 1848 revolution in Hungary was a liberal, progressive revolution, in a backward, feudal country.
Lets review the main, immediate demands:
- Free press, abolition of censorship
- Accountable government in Hungary (constitutional monarchy)
- Annual national assembly (parlament/diet)
- Religious and civil equality
- National Guard
- Burden sharing (taxes)
- Abolition of serdom
- Jury representation under equlity
- National bank
- Military have to take oath on the constitution, the foreign units hae to leave, the hungarian units on foreign lands have to return
- Release of the political prisoners
- Union with Transylvania
These demands made into law - ttbt, pretty much everything was provisional in those laws, setting up the basics, on the premise, that the next assembly will work out the details (for example, while the abolition of serfdom is effective immediately, the compesation of the nobility will be dealt in the next session).
So, im not suprised, that the slovak hardliners were hesitant.
And, after the negotiations with the nationalities - for the record, at the time of the russian intervention, but personally, i think, Szemere and the liberal cnservative assembly would have done so without it - the language and national problem was solved in a simple and effective way: the counties (wich were small enough) and the cities should decide, wich language should be there the official (legal, schools, local NG), if there is about 25% of the population speaking minority language, then those services (legal, buerocratic, school) should be provided in that language too and you can use any of those languages in dealings with the government (assembly, courts).
