Constantine Diogenes (Greek: Κωνσταντῖνος Διογένης; died 1032) was a prominent Byzantine general of the early 11th century, active in the Balkans. He served with distinction in the final stages of the Byzantine conquest of Bulgaria under Emperor Basil II, and occupied high commands in the Balkans until his arrest in 1029, as the result of his participation in a conspiracy against Emperor Romanos III Argyros. Imprisoned and forced to enter a monastery, he killed himself in 1032 during an inquest on a further conspiracy. He was the father of Emperor Romanos IV Diogenes.

Biography

Constantine Diogenes is the first notable member of the noble Diogenes family with origins from

Mylobos, as attested in a founder's inscription.[5]

The conquest of Moglena was completed in 1015 or 1016. In 1017, Diogenes and David Arianites led troops to plunder the fertile plain of

Ivan Vladislav. The Bulgarian ruler set up an ambush for his pursuers, but Basil was informed in time, and led the rest of his troops to Diogenes' aid, scattering the Bulgarians.[5]

After Ivan Vladislav's death in February 1018, Diogenes was charged with mopping up the last remaining centres of Bulgarian resistance. He took

Sermon, the ruler of Sirmium, to consolidate Byzantine control of the northern Balkans. Consequently, Diogenes invited Sermon to a meeting at the estuary of the river Sava in the Danube, where each would only be accompanied by three attendants. Diogenes had hidden his sword in the folds of his clothes, and struck Sermon down. He then marched his army into Sirmium, taking possession of the town. Sermon's wife was sent as a captive to Constantinople.[5][7]

Around 1022 or 1025, Diogenes succeeded Arianites as overall Byzantine commander (

patrikios and doux of Thessalonica, Bulgaria and Serbia".[10][11]

Diogenes had been married to an anonymous daughter of

Stoudios Monastery.[1][5][12] Theodora herself was placed in a convent, but she apparently continued to conspire with Diogenes, who planned to take advantage of Romanos's absence on campaign in the East in 1032 to escape to the Balkans. The plot was leaked to Romanos by Theophanes, metropolitan of Thessalonica, and the conspirators were arrested. Diogenes was brought to the Palace of Blachernae for interrogation by John the Orphanotrophos, but he died by suicide, throwing himself off a wall, rather than confess under torture and implicate his fellow conspirators.[3][5][13]

Constantine's son

Romanos Diogenes became a successful general and eventually rose to become emperor in 1068–71.[3][14]
