In 467 Leo, faced with increased Vandal impingement, named Anthemius, the commanding general of the Illyrian Army, as Western Emperor. Leo sent Anthemius to Italy with an army led by the commanding general of the Dalmatian Army, Marcellinus, who had previously rebelled against Ricimer. Anthemius was to secure the Western throne and recapture North Africa from the Vandals. Ricimer must have initially viewed Anthemius' appointment as undermining his position. Unlike Libius Severus, Anthemius had a proven history of military success and had family ties to the Theodosian Dynasty. However, needing the support of the Eastern Empire, Ricimer was forced to accept him. To solidify his connections with the new emperor, Ricimer diplomatically married Anthemius' daughter Alypia, and for some time lived in peace with Anthemius.
