Ottoman Empire wasnt Turkish as many of you think.Even there were no concept of being Turkish till the 1920's(jacoben takeover of anatolia).Ottoman sultans were mostly of European decendent due to foreign marriages.Ottoman Empire was a multicultural nation and anatolians were just one of the subjects of that empire.

Culture of ruling class was mixture of Greko-Persian.Thats because founders of Ottoman Empire were Persian influenced(both by culturally and both by racially) west asian/near eastern people and when they takeover anatolia they mixed their persian culture with Rum culture(or eastern Roman culture).
