About this episode

The episode discusses the challenges faced by Diocletian and Galerius in the East during the formation of the tetrarch system, including rebellion and invasion.

With the tetrarch system still taking shape, Diocletian and his Caesar Galerius come under growing pressure in the East, facing rebellion from Egypt and invasion from the Persian King Naresh. A series of hard campaigns, careful political choices and eventual victory will determine whether this new imperial order can truly secure Rome's frontiers.
