Spaniards, or Spanish people, are an ethnic group native to Spain. Within Spain, there are a number of national and regional ethnic identities that reflect the country's complex history, including a number of different languages, both indigenous and local linguistic descendants of the Roman-imposed Latin language, of which Spanish is the largest and the only one that is official throughout the whole country.
Commonly spoken regional languages include, most notably, the sole surviving indigenous language of Iberia, Basque, as well as other Latin-descended Romance languages like Spanish itself, Catalan and Galician. Many populations outside Spain have ancestors who emigrated from Spain and share elements of a Hispanic culture. The most notable of these comprise Hispanic America in the Western Hemisphere.
The Roman Republic conquered Iberia during the 2nd and 1st centuries BC. Hispania, the name given to Iberia by the Romans as a province of their Empire, became highly acculturated through a process of linguistic and cultural Romanization, and as such, the majority of local languages in Spain today, with the exception of Basque, evolved out of Vulgar Latin which was introduced by Roman soldiers. The Romans laid the foundations for modern Spanish culture and identity, and Spain was the birthplace of important Roman emperors such as Trajan, Hadrian or Theodosius I.
At the end of the Western Roman Empire, the Germanic tribal confederations migrated from Central Europe, invaded the Iberian Peninsula and established relatively independent realms in its western provinces, including the Suebi, Alans and Vandals. Eventually, the Visigoths would forcibly integrate all remaining independent territories in the peninsula, including the Byzantine province of Spania, into the Visigothic Kingdom, which more or less unified politically, ecclesiastically, and legally all the former Roman provinces or successor kingdoms of what was then documented as Hispania.
In the early eighth century, the Visigothic Kingdom was conquered by the Umayyad Islamic Caliphate that arrived to the peninsula in the year 711.
