If we take a look at the medieval world at that time, anyone labeled Saracen/Moor was a black Muslim. Around this time 85% of the blacks interacting with Europe were black muslims/saracens/moors. Arabs and saracens are not the same people. Saracens are on record of being anti-arab and went to war with them. Saracens were also the African Americans enslaved by the west.#facts so that's why he is black!!!
