Nikephoros Diogenes (Greek:Νικηφόρος Διογένης,romanized: Nikēphóros Diogenēs),Latinized asNicephorus Diogenes, was presumably a juniorByzantine emperor around 1069–1071. He was bornc. 1069 to EmperorRomanos IV Diogenes and EmpressEudokia Makrembolitissa. He was elevated to junior emperor in 1070, although he lost this position when his father was overthrown in 1071. EmperorAlexios I Komnenos, after overthrowingNikephoros III, made Nikephoros Diogenesdoux ofCrete. Nikephoros conspired against him in 1094, involving numerous confidants and relatives of Alexios, including Alexios' brother,Adrianos. For this conspiracy, he was blinded, in accordance withByzantine traditions. After this, he retired to his estates, and spent the last years of his life studying classical literature.
Nikephoros was bornc. 1069 toRomanos IV Diogenes andEudokia Makrembolitissa,[1] who married and were crowned on 1 January 1068.[2] Nikephoros was presumably elevated to junior emperor shortly after alongside his brother (and possibly twin)Leo Diogenes.[4] Although his half-brotherConstantine Diogenes was the eldest son, he was borne of Romanos' first wife Anne, who was the daughter ofAlusian of Bulgaria, and therefore was excluded from the succession when Romanos married Eudokia.[5] Nikephoros andLeo were removed as co-emperor in 1071, after the deposition of their parents byMichael VII Doukas.[6] Michael ruled until March 1078, whenNikephoros III Botaneiates overthrew him.[7] Nikephoros III was himself overthrown byAlexios I Komnenos in 1081. Alexios is said to have treated the sons of Diogenes, including Nikephoros, "as if they were his own".[1] Nikephoros was madedoux ofCrete byAlexios I Komnenos sometime in the early 1090s, likely either 1089–1091 or 1092–1094. He was also probably granted significant estates in Crete at the same time as his appointment.[1][8][9]
In June 1094 Nikephoros began to conspire against Alexios, seeking to kill him and install himself as emperor. Because he was aporphyrogenitos, being born to Romanos while he was still reigning, he had more legitimacy than Alexios, who was only related by blood to the throne through his uncleIsaac I Komnenos.[10][11] Nikephoros was also described as having many positive characteristics, such as natural charm, magnetic personality, and good looks.[10] In herAlexiad,Anna Komnene, the daughter of Alexios, describes him:[3]
He was physically strong and boasted that he rivaled the Giants; a broad-chested, blond man, a head taller than others of his generation.
— Anna Komnene,Alexiad, Book IX.6[3]
Nikephoros' revolt involved a huge number of Alexios' confidants and relatives, including former EmpressMaria of Alania, Alexios' brother-in-lawMichael Taronites, and indeed Alexios' full brotherAdrianos Komnenos. The full list of names of conspirators is not known, but they are known to include leading members of the senate, army officers, and powerful aristocrats. Very few names are given by Anna Komnene, although it is considered likely this was more because the full extent was an embarrassment than her own lack of knowledge.[12]
Nikephoros twice attempted to assassinate Alexios in person, however, the first time he was not able to do so because of the presence of a maid fanningmosquitoes off of the emperor, and the second time he was halted by a guard. Alexios became suspicious of Nikephoros, and ordered his brother Adrianos to investigate. Adrianos, who was already a member of the conspiracy, reported that he found nothing suspicious. Alexios, still suspicious, then arrested Nikephoros, and after being tortured, Nikephoros confessed the full extent of the conspiracy.[12] Nikephoros wasblinded in 1094 for conspiring against Alexios, which was astandard punishment for conspirators in Byzantine culture.[13] The punishments inflicted upon the others conspirators are not fully known, however Alexios' brother Adrianos disappears from history after the conspiracy was discovered, and Michael Taronites was only spared by the intervention of his wife,Maria Komnene, who was the sister of Alexios.[12][14][15][16]
Anna Komnene writes that though Alexios had Nikephoros blinded, he continued to care for Nikephoros afterwards, reinstating most of Nikephoros' possessions and trying to console him. However, Nikephoros was "frantic with grief, detested town-life and was fond of living on his own estate",[17] to which he retired not long after his blinding. He spent the remaining years of his life there, studying classical literature and philosophy, which were necessarily read aloud to him. He also became proficient ingeometry, by having a tutor make geometrical models for him in relief or 3D. Despite these distractions, Nikephoros "never forgot his old grudge against the Emperor, but nourished throughout a smouldering expectation of royal power",[18] and apparently plotted against him one last time; a friend in whom Nikephoros had confided informed Alexios of the plot, but Nikephoros gave up all the details when summoned for questioning, and was eventually pardoned. Nothing more is heard of Nikephoros after 1094.[13]
