Spaniards, or Spanish people, are an ethnic group and nation indigenous 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 is the most widely spoken and the only official language across the entire country.
