Leo I was emperor of the Byzantine Empire from 457 to 474 CE. He was also known as “Leo the Butcher” (Makelles) for the assassination of his patron and rival Aspar. Although his reign was lacklustre and included a serious defeat to the Vandals, he founded the Leonid dynasty, which ruled from Constantinople until 518 CE.
