Historical Explanations of North African Genetic Traces in North-Western Iberia

Abstract

We analyse seven research papers from the last twenty years that have studied North African genetic traces in Iberia and which consistently report that the highest concentrations of genetic characteristics associated with the Maghreb are found in northwest Iberia, a region both physically distant from Africa and under Andalusi political control for a shorter period than practically any other. Attempts to historically contextualise such a seemingly anomalous distribution have, we believe, been undermined by a simplistic reading of the historiography, leading to the marginalisation of any early-medieval explanation for these results, in favour of other more historically tenuous alternatives. Accordingly, these studies have been largely ignored by medievalists, further exacerbating a lack of dialogue between disciplines. We suggest that the perceived paradox between length of political control and genetic legacy should be used to challenge the orthodoxy surrounding events in the eighth century, and thus explore the possibility of a more profound Berber influence on northwest Iberia than has hitherto been contemplated, rather than being marginalised by historians interested in said period.
