The Visigoths (/ˈvɪzɪɡɒθs/; Latin: Visigothi, Wisigothi, Vesi, Visi, Wesi, Wisi) were a Gothic people who emerged in the Balkans during late antiquity. Likely descended from the Thervingi who entered the Roman Empire in 376 and defeated the Romans at the Battle of Adrianople (378), they were first united under Alaric I (395–410), whose forces alternately fought and allied with Rome before famously sacking the city in 410.
In 418, the Visigoths were settled as foederati in southern Gaul, establishing a kingdom with its capital at Toulouse. From there they expanded into Hispania, displacing the Suebi and Vandals. Defeat by the Franks under Clovis I at the Battle of Vouillé (507) ended Visigothic rule in Gaul, but the kingdom consolidated in Spain and Portugal, where it endured for two centuries.
