Michael VII was born 1050 in Constantinople, the eldest son of Constantine X Doukas and Eudokia Makrembolitissa. He was associated with his father on the throne late in 1059, together with or shortly before his newly born brother Konstantios Doukas. When Constantine X died in 1067, Michael VII was 17 years old and should have been able to rule by himself. He exhibited little interest in politics, however, and his mother Eudokia and uncle John Doukas governed the empire as effective regents.
