Leo I

Leo I d. 474, Byzantine or East Roman emperor (457–74). Chosen by the senate to succeed Marcian, he sought to counteract the preponderance of Germans in the Roman army by enlisting Isaurians. A naval expedition (468) against the Vandals of Africa failed through the incompetence or treachery of the commander, Basiliscus , who delayed his attack until Gaiseric was able to attack him with fire ships. Leo I was succeeded by his grandson, Leo II, a child of six, who died in the year of his accession; Leo I's son-in-law, Zeno, then became emperor.
