Indeed, Portugal was only established as a nation in the 12th Century a. C., with Afonso I of Portugal. After the romanization of the Iberian Peninsula, the area that would become Portugal was conquered by Germanic tribes, then by Umayyads and then reconquered by descendants of the Germanic tribes (see the origins of the Portuguese House of Burgundy). Yet, starting on the 16th century a.C., historians, such as André de Resende, started attempts to weave a story of continuity from the Lusitanians (among the many others who occupied the territory that would later become Portugal) to the Portuguese. It is from this period that the habit of referring to the Portuguese as Lusitanians arises, with the first known reference of the Portuguese as Lusitanians dating from the 15th century, by the Bishop of Évora, Garcia de Meneses.
