No. The Minorities and the Empire posts make it abundantly clear how Romans treat the Ottomans (Turks/Persians) compared to the Arabs.Do the Romans consider the Ottomans the same as Arabs?
Since the Turks and the Persians are similarly urbanized and cultured, both in the Ottoman Empire and in the Roman Empire, they are treated a lot better than the Arab bedouins in the eyes of the Romans through civilization-ism.While in this system, all Arabs are Sunnis, not all Sunnis are Arabs. Arabs, in Roman eyes, have a connotation of being religious fanatics and country bumpkins. Considering the many achievements of Arabs throughout history, this is not a fair reputation and many Romans will distinguish between the ‘sophisticated Arabs of the Abbasids’ (which many consider to have been beneficially influenced by Roman and Sassanid civilization) and their ‘fallen descendants’. That isn’t much of an improvement, but Roman prejudice is under no obligation to be more rational or reasonable than the prejudices of other peoples.
The Persians are a different matter. The history between Rhomania and Persia is a long and bloody one, but going back to the days of the Parthians the rivalry, however fierce, was viewed as that of equals. No one would ever think to call the Persians barbarians. So while the Persians of the 1600s are unquestionably Sunni, in Roman eyes they are sophisticated and intellectual. Iskandar the Great was a terrible foe, but no Roman would call him a brute. When Kaisar Andreas was summoned to the Shah on the field of Nineveh, the dialogue between the Kaisar and Prince Osman was consciously, on both sides, that of Alexander and Porus.
A side effect of that is while all good Romans perceive Islam as a false faith, when Persians speak of Islam Romans give their faith more respect. Extremely cynical when it comes to holy warriors, many Romans suspect Arab Sunni Islam as a pious cloak for simple greed, invoking God as an excuse to rape and enslave their neighbors and loot their possessions. When Latin Catholics speak, save for the exception of Franciscan friars, Romans feel the same way.
While Arab and Persian are used mainly as stereotypes, the Roman use of the word ‘Turk’ is much more nuanced. At this point there is much Turkish blood in the Roman body; Demetrios Megas, the founder of the Second Komnenid dynasty, was half-Turkish, and he is far from the only example. Yet Turkish raiders have also inflicted incalculable damage to the Empire over centuries, typically while espousing the ghazi ethos while doing so. It cannot be said that there is no prejudice when the term is used, but context is usually taken in consideration when used.
