The ancestry of modern Iberians (Spanish and Portuguese) is consistent with the geographical situation of the Iberian Peninsula in the south-west corner of Europe.-chromosome analysis had suggested Paleolithic ancestry among populations in the Iberian Peninsula and that Iberia may have played a role in the re-population of western Europe after the last glaciation.
In 711 the Iberian Peninsula was invaded by the Moors and for the following centuries Portugal would be part of Muslim Al Andalus. Portugal was born as a result of the Christian Reconquista, and in 1139, Afonso Henriques was proclaimed King of Portugal, thus firmly establishing Portuguese independence.
