Page "Nation state" Paragraph 48

* Portugal: Although surrounded by other lands and people, the Portuguese nation has occupied the same territory since the romanization or latinization of the native population during the Roman era.

The modern Portuguese nation is a very old amalgam of formerly distinct historical populations that passed through and settled in the territory of modern Portugal: native Iberian peoples, Celts, ancient Mediterraneans ( Greeks, Phoenicians, Romans, Jews ), invading Germanic peoples like the Suebi and the Visigoths, and Muslim Arabs and Berbers.

Most Berber / Arab people and the Jews were expelled from the Iberian Peninsula during the Reconquista and the repopulation by Christians.
