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.
