Constantine Diogenes (; 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 committed suicide in 1032 during an inquest on a further conspiracy. He is the father of Emperor Romanos IV Diogenes. ==Biography== Constantine Diogenes is the first notable member of the noble Cappadocian Diogenes family, which played an important role in 11th-century Byzantium.〔.〕 Constantine began his career as a commander of one of the western ''tagmata'' during the reign of Basil II (r. 976–1025), in the latter's campaigns against Bulgaria.〔 In 1014, he participated in the decisive Byzantine victory at the Battle of Kleidion (July 29),〔.〕 and he subsequently succeeded Theophylact Botaneiates as commander (''doux'') of Thessalonica with the rank of ''patrikios'', making him the second senior-most general of the Empire in the Balkans after David Arianites.〔.〕〔.〕 Following the death of Tsar Samuel of Bulgaria in October, Diogenes and Nikephoros Xiphias were dispatched to the region of Moglena as the vanguard of the Emperor and the main army. During this campaign, Diogenes constructed the fortress of Mylobos, as attested in a founder's inscription.〔.〕 The conquest of Moglena was completed in 1015 or 1016. In 1017, Diogenes and David Arianites led troops to plunder the fertile plain of Pelagonia, where they captured many prisoners and livestock.〔 Soon after, Basil II placed him in charge of the ''tagmata'' of the ''Scholai'' of the West and of Thessalonica, and tasked him with pursuing Tsar Ivan Vladislav. The Bulgarian ruler set up an ambush on his pursuers, but Basil was informed in time, and led the rest of his troops to Diogenes' aid, scattering the Bulgarians.〔 After Ivan Vladislav's death in February 1018, Diogenes was charged with mopping up the last remaining centres of Bulgarian resistance. He took Sirmium and was named its commander (''archon''), with his authority extending over the vassal Serbian statelets of Raška. His title was possibly that of "''strategos'' of Serbia" (Greek: στρατηγός Σερβίας), which is attested in a seal attributed to him.〔〔; .〕 Diogenes was ordered by Basil II to subdue Sermon, the ruler of Sirmium, in order 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 however had hidden his sword in the folds of his clothes, and struck Sermon down. Thereupon he marched his army into Sirmium, taking possession of the town. Serm's wife was sent as a captive to Constantinople.〔〔.〕 Around 1022 or 1025, Constantine succeeded Arianites as overall Byzantine commander (''strategos autokrator'') of conquered Bulgaria. In this capacity, he repelled a large Pecheneg invasion in 1027.〔〔.〕〔.〕 In the same year, he was withdrawn south to Thessalonica, but retained, at least nominally, his role as overall commander, as attested by another seal naming him "''anthypatos'', ''patrikios'' and ''doux'' of Thessalonica, Bulgaria and Serbia".〔.〕〔.〕 Constantine had been married to an anonymous daughter of Basil Argyros, brother of Emperor Romanos III Argyros (r. 1028–1034), but in 1029 he was accused, along with other prominent Balkan generals such as Eustathios Daphnomeles, of conspiring against the emperor with the ''porphyrogennete'' princess Theodora. He was transferred east as ''strategos'' of the Thracesian Theme, but as soon as his complicity in the affair was confirmed, was recalled to Constantinople. There he was imprisoned, beaten and publicly paraded in the ''Mese'' along with the other conspirators, and later tonsured and forced to enter the Stoudios Monastery.〔〔 Theodora herself was also 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 committed suicide, throwing himself off a wall, rather than confess under torture and implicate his fellow conspirators.〔〔〔.〕 Constantine's son Romanos Diogenes became a successful general and would eventually rise to become emperor in 1068–71.〔〔.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Constantine Diogenes」の詳細全文を読む スポンサード リンク
