Constantine Ducas

Constantine Ducas was a Byzantine co-emperor who lived from approximately 1081 to 1090. He was the son of Emperor Michael VII Ducas and was betrothed to Anna, the daughter of Emperor Alexius I Comnenus. However, Constantine died before he could marry her. The Ducas family was a prominent Byzantine lineage that produced several rulers, including Emperors Constantine X and Michael VII. Constantine X's attempt to establish a new dynasty was unsuccessful, and stability was only restored with the rise of the Comnenus family. The 11th century was a period of weakness for the Byzantine Empire, marked by internal divisions and external threats from groups like the Pechenegs and Seljuq Turks.123
