This is my persian empire, proud and prospering. The only problem is (don't get me wrong at this) - there are too many minorities.
I get allmost no conversion to accepted cultures in my conquered regions. Worst thing: some conquested regions are still colonies even after being part of my imperium for decades. I guess it's because literacy just won't rise and bureaucracy can't establish either (both at 100 % spendings from the first day on with invented positivism and everybody paid by the government gets 100% of his luxury needs). Even if I set a NF on promote bureaucrats - nothing happens, cause the minorities don't count as accepted cultures. And in these regions they won't turn into accepted cultures as you see above. "No valid target" for assimilation. Well, I could name one....
Had the nationalists as ruling party, had the conservatives. I don't see the problem. Played as Prussia aka German Reich before and every minority just disappeared after 30 years (no ethnic cleansing...) Any suggestions how I can start tu build up a real state with well educated and cultural accepted citizens? If you can answer my question, the persians will speak your name with honour.
Salam!
