Languages of the Ottoman Empire
The Ottomans had three influential languages: Turkish, spoken by the majority of the people in Anatolia and by the majority of Muslims of the Balkans except in Albania, Bosnia, and various Aegean Sea islands; Persian, initially used by the educated in northern portions of the Ottoman Empire before being displaced by Ottoman Turkish; and Arabic, used in southern portions of the Ottoman Empire; Arabic was spoken mainly in Arabia, North Africa, Mesopotamia and the Levant. Throughout the vast Ottoman bureaucracy Ottoman Turkish language was the official language, a version of Turkish, albeit with a vast mixture of both Arabic and Persian grammar and vocabulary.
Rise of the Ottoman Empire
When the Ottoman polity first emerged at the end of the thirteenth century under the leadership of Osman I, it had a tribal organization without a complex administrative apparatus. As Ottoman territory expanded its rulers were faced with the challenge of administering an ever-larger population. Early on the Ottomans adopted the Seljuks of Rum as models, and by 1324 were able to produce Persian-language bureaucratic documents in the Seljuk style.
