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.
Ottoman Empire
The organization of the treasury and chancery were developed under the Ottoman Empire more than any other Islamic government and, until the 17th century, they were the leading organization among all their contemporaries. This organization developed a scribal bureaucracy (known as "men of the pen") as a distinct group, partly highly trained ulama, which developed into a professional body. The effectiveness of this professional financial body stands behind the success of many great Ottoman statesmen.
