It is not accurate to group together the various Middle Eastern civilizations such as the Saracens, Slavs, and Turks into one single representation.
Each of these peoples have distinct cultures, languages, and architectural styles, and even fielded different armies in the Middle Ages.
For example, the Umayyad Caliphate copied the Byzantine army and the early Islamic Caliphate had great light cavalry which was key to their success.
Although these civilizations share the same religion and were united during the early Islamic Caliphate, it is still important to recognize the differences between them.
Just like the British, French, and Germans, who share the same religion and many cultural and linguistic similarities, it does not make sense to combine them into one civilization.
The same is true for the Turks and Slavs.
It is essential to divide them into separate civilizations to ensure that their unique characteristics are properly represented.
