(And here we must digress for definitions.... The greatness of Granada came with the Nazrite dynasty whose founder, Al-Ahmar, captured the town in 1238 from the Moorish Almohades. And Al-Ahmar, born in Córdoba, claimed descent from the pure Yemen Arabs of Kharzrej and Ansár. Which is important, since it displays the dangers of speaking, biometrically, of a _race_. The family that reigned in Moorish Granada was perhaps as Arab as the dynasties of Córdoba and Seville! And of course, the very first Arabs in Spain brought with them Berbers, negroes, Copts. Why then was Córdoba Arab, and Granada Moorish?... We require the names, and for them there are reasons. The first Moslem invasion was _Arab_: for its impulse, its energy, its leadership came straight from the Arabs. And that first Moslem culture which from Córdoba held all Spain north to Toledo, south, west, east to the seas was also _Arab_ for the identical reason. Now come fresh leaders to defend Moslem Spain; and when they have driven back Castile they disperse the Arab masters who bade them in. These hosts come in two waves: the Almoravides--_men of religion_--are Berbers from the Senegal, and the Almohades--_men of the Unity_--are Berbers from the Atlas. It is right to call them Moors since they rose to power in Morocco. And it is right to call their dominance in Spain the Moorish epoch since, after their coming, the culture of all Moslem Spain not only differed from that of Córdoba but was deeply homogeneous within itself despite political chaos.) ...
