i was merely trying to avert the discussion back to topic from religion (but yes you are partly right), both empires oppressed people for various reasons through history, the Ottomans had more religious diversity in their empire then most, another empire with similar diversity is the Russian empire, but i did not want to topic to go so off topic... if you open another thread on this topic i would be glad to discuss it further...
well, ottoman empire failed not due to the rise of nationalism, but because it was an islamic country based on the exploitation of the christians. it was the way the empire was and the events that took place which caused the rise of nationalism and not the opposite.
