I believe he's referring to berbers/Moors. They were north African and heavily influenced Spains indigenous culture.
Sidenote: I wouldn't be surprised if Amerigo Vespucci was of Serphardic/Ashkenazi Jewish descent too.
Interestingly, Columbus was just a Netanyahu of his day.
He was wanted in Europe for his cruelty and brutality to both Spaniards and natives.
I think he was on the run for some time.
