Ottoman culture evolved over several centuries as the ruling administration of the Turks absorbed, adapted and modified the cultures of conquered lands and their peoples. There was a strong influence from the customs and languages of Islamic societies, Turkish "the official language for the Empire, notably Arabic because of the origins of Islam, while Persian culture had a significant contribution through the heavily Persianized Seljuq Turks, the Ottomans' predecessors. Despite newer added amalgamations, the Ottoman dynasty, like their predecessors in the Sultanate of Rum and the Seljuk Empire, were thoroughly Persianised in their culture, language, habits and customs, and therefore, the empire has been described as a Persianate empire." Throughout its history, the Ottoman Empire had substantial subject populations of Byzantine Greeks, Armenians, Jews and Assyrians, who were allowed a certain amount of autonomy under the confessional millet system of Ottoman government, and whose distinctive cultures enriched that of the Ottoman state.
As the Ottoman Empire expanded it assimilated the culture of numerous regions under its rule and beyond, being particularly influenced by Byzantium, the Arab culture of the Islamic Middle East, and the Persian culture of Iran.
As with many Ottoman Turkish art forms, the poetry produced for the Ottoman court circle had a strong influence from classical Persian traditions; a large number of Persian loanwords entered the literary language, and Persian metres and forms (such as those of Ghazal) were used.
