In addition to the other conquests, the Empire established a presence in Visigothic Hispania, when the usurper Athanagild requested assistance in his rebellion against King Agila I. In 552, Justinian dispatched a force of 2,000 men; according to the historian Jordanes, this army was led by the octogenarian Liberius. The Byzantines took Cartagena and other cities on the southeastern coast and founded the new province of Spania before being checked by their former ally Athanagild, who had by now become king. This campaign marked the apogee of Byzantine expansion.
