In 457 OTL Emperor Marcian died and lacking heirs (his marriage with Pulcheria never consumated because she had taken vows as a nun...) The powerful Magister Militum per Orientem Aspar proposed Tribune Leo as candidate for the throne (future Leo I)...
However Marcian had a daughter from a previous marriage which was married to Magister Militum per Thraciae Anthemius (future Emperor Anthemius of the West in OTL)
WI Anthemius pushes his own candidacy to the throne against Aspar and Leo I as the nearest relative to the late Emperor Marcian? Being Magister Militum per Thraciae he was controlling several Legions in Illyricum and Constantinople...
Could he end up being Emperor of the East instead of West? And how is that affecting Roman history?
