Aspar attained the consulship in 434 after campaigning in Africa.[2] However, Aspar could not become emperor because of his Arian religion. Instead, he played the role of kingmaker with his subordinate, Marcian, who became emperor by marrying Theodosius II's sister Pulcheria. However, Marcian's successor Leo I eventually turned on him. In 471 Aspar was killed together with his son Ardabur in an assault by palace eunuchs. This came about because Ardabur attempted to bribe Leo's soldiers, the Isaurian Excubitors, with no success, and Leo viewed both son and father with suspicion.
Aspar was the teacher of Theodoric the Great, who later became king of the Ostrogoths. Aspar had another son, Ermanaric, with the sister of Theodoric Strabo.[3] Aspar's wife was an Ostrogoth, as the Ostrogoth King Theodoric was her nephew.[2] A cistern attributed to him still exists today in Istanbul.
