Diocletian's New Administrative System

Diocletian decided that the one thing he liked about the military being in charge was the clear chainge of command. So when he kicked the soldiers back to the frontiers, he essentially kept the structure of the military in place for his new bureaucracy. Bureaucrats were grouped into cohorts, just like in the legions, made answerable to senior officials. To make sure that no one missed the point, diocletian even made the official uniform of his civil service a military cloak rather than a civilian toga.
