Hi all and specifically Mustafaa I HAVE visited those places and I have tons of friends that are from both Morocco and Mauritania They come as do most speakers of Arabic in many many different colors Yes the Arabs came to N Africa and of course they mixed with the people That is the normal and logical conclusion that there are elements of Arab and African culture in the culture of North Africa which came to be known in the West as Moorish culture On an interesting side note I myself am bi racial half Euro American half African American and I am often mistaken for Mauritanian or Moroccan BY OTHER MEMBERS OF THOSE COUNTRIES That might be something to think about Nourah
