Co-emperor of the Byzantine Empire / From Wikipedia, the free encyclopedia
Constantine Doukas or Ducas (Greek: Κωνσταντίνος Δούκας, Kōnstantinos Doukas), (late 1074 – c. 1095) was Byzantine junior emperor from 1074–1078, and again from 1081–1087. He was born to Emperor Michael VII and Empress Maria of Alania in late 1074, and elevated to junior emperor in the same year. He was junior emperor until 1078, when Michael, and was replaced by Nikephoros III Botaneiates. Because Constantine was not made junior emperor under Nikephoros, his betrothal to Olympias, the daughter of Robert Guiscard, was broken, which Robert Guiscard used as a pretext to invade the Byzantine Empire. John Doukas forced Nikephoros to abdicate to Alexios I Komnenos in 1081, and shortly after Alexios elevated Constantine to junior emperor under himself. Constantine remained junior emperor until 1087, when Alexios had a son, John II Komnenos. Constantine died in c. 1095.
