Moors from Baghdad, Turkey threatened European Christians
Moor traditionally referred to Muslim people from North Africa and Southern Europe (namely Spain, Portugal and Sicily).
In broader terms, the word “Moor” was used by Europeans to refer to any Muslim; but relating it to Baghdad (which is in Iraq) or Turkey, both of which are in the Middle East, is inaccurate on Ras' part; unless he is interchanging “Moor” with “Muslim” or referring to anyone who is colored.
The fact that Moor did generally refer to inhabitants of North Africa, could explain why Ras uses the term; though North Africans range in color and are not particularly dark skinned.
When he says that Moors threatened European Christians, he refers to the threat posed to Europe by Arab and Berber Muslim armies who conquered Spain and were poised to spread into the rest of Europe before the Battle of Tours in 732.
Later, the Ottoman Turks, who were also Muslim, but not Moors (or Arabs for that matter), threatened Europe and conquered much of south-eastern Europe before being defeated at the Battle of Vienna in 1683.
