Zoë (Greek: Ζωή "life"), the daughter of Constantine VIII, succeeded her father on his death as the only surviving member of the Macedonian dynasty, along with her sister Theodora. Her three husbands, Romanos III (1028–1034), Michael IV (1034–1041) and Constantine IX (1042–1050) later ruled alongside her. From April 19 to June 11, 1042 she reigned as Byzantine Empress alongside her sister Theodora.
Constantine IX Monomachos, Latinized as Constantine IX Monomachus (Greek: Κωνσταντῖνος Θ΄ Μονομάχος), reigned as Byzantine emperor from June 11, 1042 to January 11, 1055. He had been chosen by the Empress Zoe as a husband and co-emperor in 1042, although he had been exiled for conspiring against her previous husband, Emperor Michael IV the Paphlagonian. They ruled together until Zoe died in 1050.
