According to Bernard Reilly,[2]: 13  during the taifa period genealogy continued to be an obsession of the upper classes in al-Andalus. Most wanted to trace their lineage back to the Syrian and Yemeni Arabs who accompanied the invasion. In contrast, tracing descent from the Berbers who came with the same invasion "was to be stigmatized as of inferior birth".[2]: 13  Reilly notes, however, that in practice the two groups had by the 11th century become almost indistinguishable: "both groups gradually ceased to be distinguishable parts of the Muslim population, except when one of them actually ruled a taifa, in which case his low origins were well publicized by his rivals".[citation needed]
