A grand line of distinction existed among the Moslems of Spain, between those of Oriental origin and those from Western Africa. Among the former the Arabs considered themselves the purest race, as being descended from the countrymen of the Prophet, who first raised the standard of Islam; among the latter, the most warlike and powerful were the Berber tribes from Mount Atlas and the deserts of Sahara, commonly known as Moors, who subdued the tribes of the sea-coast, founded the city of Morocco, and for a long time disputed with the oriental races the control of Moslem Spain.

Among the oriental races the Abencerrages held a distinguished rank, priding themselves on a pure Arab descent from the Beni Seraj, one of the tribes who were Ansares or Companions of the Prophet. The Abencerrages flourished for a time at Cordova; but probably repaired to Granada after the downfall of the Western Caliphat; it was there they attained their historical and romantic celebrity, being foremost among the splendid chivalry which graced the court of the Alhambra.
