Nikephoros Diogenes, Latinized as Nicephorus Diogenes, was a junior Byzantine emperor from 1070–1071. He was born in c. 1069 to Byzantine Emperor Romanos IV Diogenes and Empress Eudokia Makrembolitissa. He was elevated to junior emperor in 1070, although he lost this position when his father was overthrown in 1071. Emperor Alexios I Komnenos, after overthrowing Nikephoros III, made Nikephoros doux of Crete, and made him a general. 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 with Byzantine traditions. After this, he retired to his estates, and spent the last years of his life studying classical literature.

Nikephoros III Botaneiates, Latinized as Nicephorus III Botaniates, was Byzantine emperor from 7 January 1078 to 1 April 1081. He was born in 1002, and became a general during the reign of Byzantine Emperor Constantine IX Monomachos, serving in the Pecheneg revolt of 1048–1053. His actions in guiding his forces away from the Pechenegs following the Battle of Zygos Pass, in which they suffered eleven days of harassment before finally reaching the Byzantine city of Adrianople, attracted the attention of fellow officers, and he received the title of magistros as a reward. Nikephoros served in the revolt of Isaac I Komnenos against the Byzantine Emperor Michael VI Bringas, leading forces at the decisive Battle of Petroe. Under Emperor Constantine X Doukas he was made doux of Thessalonica, where he remained until c. 1065, when he was reassigned as doux of Antioch. While doux of Antioch, he repelled numerous incursions from the Emirate of Aleppo. When Constantine X died in 1067, his wife, Empress Eudokia Makrembolitissa, considered taking Nikephoros as husband and emperor, but instead chose Romanos IV Diogenes. The need for an immediate successor was made pressing by the constant Seljuk raids into Byzantine Anatolia, and Eudokia, Patriarch John VIII of Constantinople, and the Byzantine Senate agreed that their top priority was the defense of the empire and that they needed an emperor to lead troops to repel the Turks. Nikephoros was the favorite candidate of the senate, but was in the field leading troops in Antioch and was still married. Romanos, once chosen to be emperor, exiled Nikephoros to his holdings in the Anatolic Theme, where he remained until he was brought out of retirement by Emperor Michael VII and made kouropalates and governor of the Anatolic Theme.
