Nicéforo III
The tonsured Caesar retained some influence on political events. With the collapse of imperial authority late in Michael VII’s reign, he advised his nephew to abdicate and become a monk when Nikephoros III Botaneiates threatened Constantinople in 1078, and in 1081 he fled Constantinople to join Alexios Komnenos and to persuade him to revolt against Botaneiates and claim the throne. It was also John Doukas, who arranged for the marriage of his granddaughter Irene Doukaina to Alexios Komnenos over the objections of the latter's mother Anna Dalassene. In this change of circumstance, he abandoned the monastic habit and Alexios allowed him to resume his old position as Caesar. Remaining part of the court, he continued to advise the emperor until his death in c. 1088.
