Theodosius Named Co-Emperor

A father secures his dynasty's future

Byzantine Emperor Maurice proclaimed his young son Theodosius as co-emperor, a time-honored strategy for securing dynastic succession in the volatile world of imperial politics. The move was designed to ensure a smooth transition of power, but Maurice's reign would end in tragedy when he and his sons were overthrown and executed by the usurper Phocas. The fate of Maurice's dynasty became one of the most poignant tales of Byzantine political violence.
