Did diocletian save the roman empire?
Diocletian could not save Rome, too much damage was done.
However he did try to. Diocletian could not save Rome because he
could not live forever, and he knew it, which may have been one of
the reasons why he became the first emperor to retire. He did all
he could to reorganize the empire and make it efficient again, but
he had no control over what would be done to it after his
death.
