Nikephoros III Botaneiates, deposed Byzantine Emperor (born c.1002)

Nikephoros III Botaneiates, Latinized as Nicephorus III Botaniates, was Byzantine Emperor from 7 January 1078 to 1 April 1081. He became a general during the reign of Byzantine Emperor Constantine IX Monomachos, serving with distinction during the Pecheneg revolt of 1048–1053. In 1057 he aided Isaac I Komnenos in overthrowing Emperor Michael VI Bringas, leading forces at the decisive Battle of Petroe. Under the Emperor Constantine X Doukas Nikephoros was made doux, first of Thessalonica and subsequently of Antioch. In the latter position he repelled numerous incursions from the Emirate of Aleppo. Constantine X died in 1067 and Empress Eudokia Makrembolitissa married Romanos IV Diogenes; Nikephoros, who had also been a candidate for Eudokia's hand and the position of emperor, was exiled and remained in retirement until Emperor Michael VII summoned him to serve as kouropalates and governor of the Anatolic Theme.

The foundation of Constantinople in 330 AD marks the conventional start of the Eastern Roman Empire, which fell to the Ottoman Empire in 1453 AD. Only the emperors who were recognized as legitimate rulers and exercised sovereign authority are included, to the exclusion of junior co-emperors who never attained the status of sole or senior ruler, as well as of the various usurpers or rebels who claimed the imperial title.
