During the reign of Nikephoros, he had to contend with four revolts and plots before the revolt of Alexios I Komnenos which ultimately ended his reign. The first revolt was that of Nikephoros Bryennios, who had contended for the throne of Michael VII at the same time as Nikephoros III; Nikephoros, now too old to command armies, sent Alexios Komnenos to defeat him. Once Bryennios was defeated, Nikephoros III had him blinded, but granted him and his partisans amnesty.
