What was the impact of Constantine?

Answer 1

Edward Gibbon suggested that Constantine's conversion to Christianity was one of the principal causes of the fall of the western Roman Empire, which ceased to exist 139 years after his death. At first glance this may seem so far removed from the time of Constantine as to preclude a direct relationship, but Constantine put in place a process that was irreversible.

Another impact of Constantine's conversion to Christianity was the eventual conversion of the Roman Empire to Christianity, although once again this did not really occur until long after his death.
