Isaac I Komnenos

Isaac I Komnenos (c. 1007–1060), the first Komnenian Byzantine emperor, reigned from 1057 to 1059. Son of General Manuel Erotikos Komnenos, he commanded the eastern field army before leading the 1057 revolt against Michael VI, winning at Hades and forcing his abdication.

As emperor he cut salaries and confiscated Church lands to rebuild the army and treasury. These measures provoked opposition, above all from Patriarch Michael Keroularios, whom he exiled in 1058. After campaigning against the Pechenegs in 1059, he fell ill and abdicated in favour of Constantine X Doukas, dying as a monk in 1060.
