The base Celtiberian population remained in various stages of Romanisation, and local leaders were admitted into the Roman aristocratic class.
Roman Hispania
The Romans improved existing cities, such as Tarragona (Tarraco), and established others like
Zaragoza (Caesaraugusta), Mérida (Augusta Emerita), Valencia (Valentia), León ("Legio Septima"), Badajoz ("Pax Augusta"), and Palencia.[24] The peninsula's economy expanded under Roman tutelage. Hispania supplied Rome with food, olive oil, wine and metal. The emperors Trajan, Hadrian, Theodosius I, the philosopher Seneca and the poets Martial, Quintilian and Lucan were born in Spain. The Spanish Bishops held the Council at Elvira in 306.

The first Germanic tribes to invade Hispania arrived in the 5th century, as the Roman Empire decayed.[25] The Visigoths, Suebi, Vandals and Alans arrived in Spain by crossing the Pyrenees mountain range.[26] The Romanized Visigoths entered Hispania in 415. After the conversion of their monarchy to Roman Catholicism, the Visigothic Kingdom eventually encompassed a great part of the Iberian Peninsula after conquering the disordered Suebic territories in the northwest and Byzantine territories in the southeast.
The collapse of the Western Roman Empire did not lead to the same wholesale destruction of Western classical society as happened in areas like Roman Britain, Gaul and Germania Inferior during the Dark Ages, even if the institutions, infrastructure and economy did suffer considerable degradation. Spain's present languages, its religion, and the basis of its laws originate from this period. The centuries of uninterrupted Roman rule and settlement left a deep and enduring imprint upon the culture of Spain.
