The post-Roman period in Iberia is yet to be studied in depth using ancient DNA. Our research focuses on understanding population genetic changes during this time in the Iberian Levante. This Mediterranean region is interesting because it became a cultural crossroads after intense Romanization, followed by a decline during the Visigothic era, a Byzantine invasion and later becoming a jewel of Islamic agriculture. The main focus of the research is on the Medieval Islamic period. During the five centuries of Islamic rule, and according to historical records, many Arab and North African settlers were attracted to Xarq Al-Andalus. We sequenced 13 early to late Medieval genomes with coverages ranging from 0.3X to 2.3X from the Valencian region in eastern Spain and discovered widespread North African admixture and foreign uniparental markers in the Andalusian Islamic rural society. These results are the more striking when compared to the modern Spanish population, which displays little surviving genomic evidence for this relatively recent admixture episode. We identify one major historical event in the 17th century, potentially responsible for the disappearance of the North African ancestry in eastern Spain. On the other hand, we did not find a clear Arab genetic contribution, consistent with the view that Arabs were a minority ruling elite. However, the genomic results of two samples dated to the 6th-7th century moment of the Byzantine invasion suggest that the admixture trend may have started earlier, during late Roman times. These two samples are father and daughter, found in a borderland territory between Visigothic and Byzantine rule, and display a significant degree of Near Eastern ancestry but with clear Iberian affinities. In conclusion, we see evidence that the Spanish Levante suffered two genetic transformations in a relatively short period of time -a few centuries -within the last thousand years. This dual genomic transformation saw the arrival of North African ancestry to eastern Iberia in high proportions only to later disappear almost completely. However, the North African genetic legacy in Spain survived in some ways until our days, mostly in the form of paternal lineages E1b and maternal lineages U6a which we clearly identified being introduced for the first time during the Islamic period.

Basically the reconquista decimated the Moorish admixed Southern Iberians.

Interesting, I always suspected that Arab admixture in Iberia was very limited and that most of it came from North Africa instead of Arabs.

Reconquista was a bloody parade frequented by asturians rednecks that destroyed the most rainbow nation of Medieval Europe with tons of italians, jews, swedes, lebaneses, greeks, french, arabs, germans, celts and berbers. Such a shame Iberia became this homogeneous place... Not to mention how advanced and civilized was this Great Emirate of Cordoba and All Andalus.

It was totally ruined, but at least after some centuries the Illuminates replaced it and founded their new Golden Jewel called California.

It is an unknown fact, but not only the christian reconquers expelled the native southern spanish population, the almoravid muslims made a massive deportation of native southerners (but christian) in 1126:

And Slavs

And Slavs

Oh yes, there are many evidences of east europeans working in All Andalus for the invaders.

yes they were called "saqaliba" were slavic slaves brought mainly from central and eastern Europe some of them reached high social ranks

you can't compare a small event like this one to the massive expulsion and massacre of the native southern population by the christian forces you're simply biased because of your christian background.

Do you have relative or relatives who had muladi/andalusi ancestors?
