Pardon me while I put on my nerd hat.
I find it interesting that the Redguard race is continually compared to Arabian cultures simply due to the preponderance of Redguard NPC's to be found using "Curved swords....curved...swords."
The Redguard, as a proto-culture, is actually more akin to a hybridization of the Mongol and Far Eastern cultures, with their pre-Tamriel history being for more akin to that of Ancient China, with a minor difference in total land size, (though with a slightly modern dash of being firebombed into being unable to further sustain their civilization by some unspecified disaster), their original homeland is a medium sized nation of islands to the west of Tamriel (Tamriel is a continental mass for those of you that woke up in Skyrim one day and didn't realize you were on a planet called Nirn that actually has other land masses on it.) called Yokuda, and their pre-exodus culture is very akin to Far Eastern proto-cultures around the time of the Yellow Emperor, and not in any way similar to the any of Earth's Middle Eastern proto-cultures in any way with the visual exceptions of the Redguard race obviously not being visually oriental and their military evolution appearing to follow more closely to Persian culture. But that whole living in a desert thing....well thats fairly recent, in Tamrielic anthropological terms.
So while some cultures of Nirn can be pretty easily identified as alloys of real world cultures, the Redguard culture is not so easily recognized an alloy as to simply say, curved sword, pointy turban hat, lives near a big desert, dark of complexion...must be Arabian....cause in all fairness...its not.
