Languages of the Ottoman Empire
The language of the court and government of the Ottoman Empire was Ottoman Turkish, but many other languages were in contemporary use in parts of the empire. Although the minorities of the Ottoman Empire were free to use their language amongst themselves, if they needed to communicate with the government they had to use Ottoman Turkish.

Despite being a part of the Ottoman Empire, during the four centuries of Ottoman rule Mosul was considered "the most independent district" within the Middle East, following the Roman model of indirect rule through local notables. "Mosuli culture developed less along Ottoman-Turkish lines than along Iraqi-Arab lines; and Turkish, the official language of the State, was certainly not the dominant language in the province."
