Spaniards, or Spanish people, are an ethnic group native to Spain. Genetically and ethnolinguistically, Spaniards belong to the broader Southern and Western European populations, exhibiting a high degree of continuity with other Indo-European-derived ethnic groups in the region. Spain is also home to a diverse array of national and regional identities, shaped by its complex history. These include various languages and dialects, many of which are direct descendants of Latin, the language imposed during Roman rule. Among them, Spanish (also known as Castilian) is the most widely spoken and the only official language across the entire 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.
