Nikephoros (Caesar)

Nikephoros (Greek: Νικηφόρος), also Latinized as Nicephorus or Nicephoros, was the second son of Byzantine emperor Constantine V (reigned 741–775) and Caesar of the Byzantine Empire. He was engaged in a plot against his half-brother, Leo IV (r. 775–780), which cost Nikephoros his title, and was the focal point of numerous usurpation plots during the subsequent reigns of his nephew, Constantine VI (r. 780–797), and of Constantine's mother, Irene of Athens (r. 797–802). He was therefore blinded and exiled to a monastery for most of his life, probably dying in the island of Aphousia sometime after 812.

Nikephoros was born in the late 750s (circa 756/758) to Emperor Constantine V and his third wife Eudokia. Nikephoros was Constantine's third son overall, following the future Leo IV, who was born 750 to Constantine's first wife Irene of Khazaria, and Christopher, who was born in circa 755 to Eudokia. Either Christopher or Nikephoros were possibly twin brothers to Eudokia's and Constantine's only daughter, Anthousa. On April 1, 769, Eudokia was crowned as Augusta, and on the same occasion Christopher and Nikephoros were crowned and raised to the rank of Caesar, while their younger brother Niketas was made Nobilissimus. Nikephoros had two other younger brothers, Anthimos and Eudokimos, who were also named Nobilissimi at later dates.
