"Constantine IX Monomachos, Latinized as Constantine IX Monomachus (Medieval Greek: Κωνσταντῖνος Θ΄ Μονομάχος, romanized: Kōnstantinos IX Monomachos; c. 1000 – 11 January 1055), reigned as Byzantine emperor from 11 June 1042 to 11 January 1055. He had been chosen by the Empress Zoë 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 Zoë died in 1050.
During Constantine´s reign, the Byzantine Empire fought wars against groups which included the Kievan Rus´ and the Seljuq Turks. In the year before his death, the split between the Eastern Orthodox and Roman Catholic Churches took place." - (en.wikipedia.org 12.12.2019)
