The Battle of Barcelona in 512 was the culmination of the conflict for the Visigoth crown following the death of Alaric II, which pitted the supporters of the deposed king Gesalec against the Ostrogothic troops of General Ibbas, who supported the regency of Theodoric the Great in Hispania on behalf of his grandson Amalaric. The battle, fought near Barcelona, ended with a decisive victory for Ibbas, which eliminated any real possibility of Gesalec's restoration.
